I wonder if diet is connected with hearing loss (besides trauma) as it is with dementia. Because genetics can be dormant or triggered according to one’s diet more or less

[@helentee9863]

That's simple. Loud noises of any sort can damage hearing. To protect hearing don't listen to music too loud, particularly on earphones/earbuds,and if operating loud machinery use ear protecters

[@asiawilk]

I am glad to hear that blue light isn't actually damaging. My full time job is working on the computer,but I never opted to get the blue light filter which would always shock my optometrist. But the truth is, I need to see colours correctly with my job and the filter interferes with that too much. I was always worried I was choosing to ruin my eyes to be able to pay my bills 😅

Blue light by itself is not dangerous, but the narrow band blue light peak emitted by most LED backlit screens is. It's high intensity of light concentrated in very narrow spectrum. If it was spread out over wider frequency band (like natural light sources), then it wouldn't have such high toxicity for the tissue.

they didn't say blue light isn't damaging to your eyesight or health, they just said there is no reasearch can claim such thing as to right now meaning there is no reaserch who shows blue light is damaging or not dammging to the eyesight therefore blue light can still be damaging and you simpley don't know it yet.

One thing I learned from experience is that the glasses won't make your vision worse, BUT since I got my glasses way too late (in my 20s) I had already gotten used to not seeing right(shortsighted + astigmatism). Then as I started to wear them every waking hour, I got used to seeing perfectly fine. So now, when I take them off, I trip and run into stuff more often than I did before, but that is not because I see worse but because I am no longer compensating by being exceptionally careful. I think that often causes people to mistakenly believe their vision got worse.

[@DoubleOpposite]

How do you know glasses won't make your vision worse? Do you know excessive near work leads to myopia? Aren't you familiar with primate studies 30 years where they had minus lenses put in front of their eyes, and they developed myopia. Hard to fight the general ignorant public that doesn't want to hear anything/do his own research about this subject. 1.Take 100 7 year old kids who are illiterate and check their vision 2-3 years after 2.Take 100 7 year old kids who do 10hrs reading at 30cm and check their vision 2-3 years after 3.Take 100 7 year old kids who are always outside but are put with -3.00D minus lenses and check their naked vision 2-3 years after. scenario 2+3 = Myopia, and this is proven by science.

The monkey and the kids wearing the minus lenses scenarios are not really proving that nearwork causes myopia because the lenses are already a huge factor, so perhaps reference more examples where they only have nearwork activities involved in the experiment to better support your argument.

If something hits your eye but you’re eye is closed will not end up getting low vision. I rinsed something off my eye lids in the shower today and I had water fall on my face for five minutes and my mom told me that water from a shower falling on your eyes could cause permeant damage and oh dear I had shower water fall on my face for five minutes but my eyes were closed the whole time I did it. If someone rinses his or her face under shower water for five minutes with shower water with his or her eyes closed would the water falling on your face still damage the person’s eyes and cause the person to get low vision even though the person’s eyes were shut while the water was falling on the person’s face?

Contacts can't got lost behind the eye, but they can get lost at the top. Happened to me when I first was getting them in 7th grade. The first time one somehow got stuck past my eye lid and when I was putting on the replacement, it fell out and the doc was like I've never seen that before. The floaters one is the most scary to me because my current eye doctor told me that the vein to my eye is pretty thin and said my eye could fall out if it gets thin enough, so if I start to see more and more floaters, to contact her ASAP.

[@Sorrynotsorry721]

[@Nika_02SB]

Your eye won’t fall out. If you see floaters or flashes that COULD be a sign of a retinal detachment which could lead to blindness

[@helentee9863]

The problem is that the retina, the patch of nerve cells at the back of the inside of the eye, which react to light and without which we can't see,needs a good blood supply. If something interrupts that blood supply, such as damage to the capillaries (very small blood vessels)that carry blood to the retina,then those cells can be damaged. Once the retina is damaged,there is nothing that can be done to fix it. BUT, there are things that can be done to improve the blood supply before that happens/re attach your retina if it detaches ,such as laser surgery. If you have bad floaters,this can mean there is damage to the capillaries, though generally it doesn't. But an eye check is a good idea . If you have bad floaters,then suddenly loose an area of sight in your eye,like a dark spot that doesn't move,you need to seek treatment straight away,as you DO have damage to the capillaries/a detached retina The sooner you get treatment, the more likely it is that your retina/its blood supply can be repaired and your sight will be fine Never take chances with your sight

[@vampsprite69]

happened to me too😭😭😭freaked out while trying to find my contact bc i thought i dropped it but it was slid to the right of my eye

[@TwoTreesFarm]

The top, sides, and bottom. Basically the contact won't go all the way behind the eye, but it can get stuck anywhere around the edges as far back as your conjunctiva connects. It happens to me fairly often (as in a few times a year), usually when my eyes are really dry and the contact catches on my eye lid and rolls up.

[@stefaniec876]

I was literally "prescribed" eye exercises by my ophthalmologist. He said my problem wasn't myopia but rather exhaustion of my eye muscles, which was later confirmed by a dysautonomia specialist.

[@blasianking4827]

They stated that eye exercises don't help with myopia and other vision-impairing conditions; so if a professional told you that it wasn't myopia and rather a specific problem with your eye muscles than eye exercises can probably help somewhat since it has to do with your muscles. What they mean is that eye exercises won't help you with said conditions, or magically improve your vision from where it is now. It can help with eye strain.

It's not a myth. These two medical doctors, like most medical doctors, wildly unscientific, are clueless about the basic science and cannot even infer a truly logical consequence of the hypothesis that they wish to refute [01:16]. The conclusion that blue light damages eyes owes to decades of research. One could question much of the data's clinical relevance to freeliving humans. But these medical doctors spout nonsense by reducing it all to a myth due to media report of a 2018 study on cells not even retinal. And refuting the hypothesis by alleging that it entails a "pandemic of blindness" is sheer inanity. - E Zrenner, "[Light-induced damage to the eye]", _Fortschr Ophthalmol,_ 1990;87 Suppl:S41-51.

It's proably inferior to the current cancer treatment options out there.

This is basically what the current radiation/x-ray therapy methods already do, but at a higher efficiency.

[@dzamija922]

The problem with that is that visible blue light can't really penetrate our skin and get to the cancer. If it could, you'd be able to see your screen through your hand. That's why we use other types of radiation that can actually penetrate the body and attack the cancer cells

[@daizbid]

One thing to note (and this is explained in the video but most people seemed to not actually watch it, just read the thumbnail): while blue light is not harmful to your eyes, it can still affect your circadian rhythm. Blue light sends the signal to our brain that it's daytime, and that we should be more alert. Setting a blue light filter on your phone, computer, etc., using blue light filtering glasses, or simply limiting nighttime screen use can all be beneficial to your sleep, and thus to your health.

[@Sergeeeek]

I don't think this is scientifically proven either. I saw studies that didn't find correlation between blue light and sleep. What did seem to have a correlation is how engaged you are when you're using your phone/computer before bed. For example if you're reading a very exciting book before bed it doesn't matter if it's on a phone screen with blue light or on a piece of paper - you're going to have trouble falling asleep. I don't have a link, but I found it by just googling.

[@RedPC4857]

I think people think the only reason blue light is damaging is because it can so-called "cause eye deterioration". Yes and no. Blue light doesn't directly affect your eyes, but because your eyes don't really close when you're playing a game or concentrating on a video, it can cause eye strain and dryness, which then those symptoms lead to blurriness.

Unfortunately, you could only expose the outer layer of the tumor, and not even all of that layer. Also, the intensity of light required would generate heat and could also damage adjoining tissues. Yes, light/laser is an available tool, but if the tumor is that readily accessible, it could be removed more completely and easily by freezing - such as a wart.

[@kana-is-sleepy]

Thank you for mentioning the blue light myth! I constantly get asked about buying blue-light blocking for my glasses, and I always say no, although for a different reason than most people. I have narcolepsy, a disorder that severs the connection between my circadian rhythm and the rest of my brain and causes neurotransmitter imbalances as a result. In a healthy brain, a neurotransmitter called orexin directs when other wakefulness promoting neurotransmitters are released. As just one example, dopamine levels spike in the morning, giving you the urge to get out of bed. My orexin-producing neutrons are mostly or completely gone as of an autoimmune attack that happened when I was 14. With no orexin to direct the brain, dopamine, norepinephrine, histamine, serotonin, GABA, and other important neurotransmitters don't get released in the normal organized way. In the same way that a diabetic has to do the job of their pancreas, I have to do the same for my hypothalamus through medications and lifestyle changes. Blue light promotes wakefulness, so I use it during the day to remind my brain that it's wakefulness time. At night, my lights switch to yellow, which helps my brain settle down for sleep. It’s not a life-changing strategy by any means, and I definitely need several medications as well, but it does help!

[@sarahvandekerkhof1458]

Interesting! I have narcolepsy too. Unfortunately, blue light doesn't do a good job at keeping me awake. I know this because i tried gaming during the pandemic but i wasn't taking enough medication at the time and i couldn't even do it for 10 minutes (which resulted in losing an hour of trying to stay awake). Games on the smartphone are even worse. It think it is more exhausting because the screen is smaller.

[@kana-is-sleepy]

@@sarahvandekerkhof1458 That’s fair! Even among narcoleptics, the strategies and medications that work for one person may not work for another. I should clarify that I can’t just use blue light on my phone, I have to use certain light bulbs in floor lamps to get the best effect. I have a color-changing smart bulb in my floor lamp, and I use a combo of routines on the Cync and Google Home apps to control it throughout the day. I also have a regular 60-watt equivalent LED daylight light bulb in my desk lamp lamp, since I don’t need that one to turn on/off or switch colors on it’s own. Blue light from my phone doesn’t help much with wakefulness during the day, but I definitely need the night shift filter at night to help combat that wonderful narcolepsy insomnia 🙃 I always ended up playing ACNH until 4 AM when I was home at the beginning of the pandemic lol

When I have lost a contact into the top or side of the eye, I have been able to move it forward by gently rubbing the top of my closed eye. The lens is usually folded, but I can then extract it.

I wear contact lenses, and sometimes when they get dry and I rub my eyes they may get folded and get stuck usually on top of my eyes.

[@DanSpotYT]

Have a history of glaucoma in the family and my pressures were elevated. Dr. gave me drops to rule out that issue and only used on one eye. Pressure dropped but not enough to warrant continuation. Turns out that my cornea is thicker than usual (my brother has the same) so the Dr. took me off the drops. If I recall correctly, those drops may cause eyelashes to grow more but also, over time, could have made my blue eyes become darker - which isn't a bad thing, just not a desired outcome as I and others rather fancy their color.

[@miiraducale820]

The drops that make your eye lashes grow are prostaglandins so the drugs such as bimatoprost, latanoprost, travoprost and tafluprost. Usually they are used in both eyes since they can darken the iris. The iris is less likely to change in colour if your eyes are fully blue with no specs if green and brown. There are no changes in colour once you stop using the drug however.

Blue light? I was checked in school and again at 18 years old during regular checkups and passed with normal color vision. After being around welding for a dozen years I failed the color vision section of my examination. A 21 picture battery and I missed all 7 blue cards. I work in aluminum ships etc with very reflective mirror-like walls. Even in another room facing away from the welding we get significant blue light. The doctor giving the exam told me I was lying about passing previously because (in his words) color vision doesn't change. He didn't care to check my record. I mention these results to all my eye doctors over the years (I am now 62) and get mixed results including "Hmm" and "I did not know that". More than one has stated: Without a doubt, the intense blue light from welding has lowered the sensitivity of my blue cones. Many welders over the years have been blinded by the light radiation. While UV is blamed for burns and blisters on the eyes, welding light contains intense visible (red green and blue) light, ultraviolet, and infrared radiation. I think it's time to update your myths. At least include exceptions and qualifiers in your language.

I actually had more than one cases where one of my contact lenses was folded and hiding probably where the top of my eyeball is, so not really at the far back. I felt it being loose and when blinking I lost it, assuming it had fallen somewhere in my bathroom. The first time that occurred, I thought nothing of it and just replaced it. I didn’t realize until the next day when I woke up with an irritated eye that there was something in there. Had to lift my upper eyelid, look down and do a massaging move to bring down whatever was up there. It was folded in half and tucked in there, and I could feel nothing except a very mild irritation. The following times a similar contact “loss” happened I knew exactly where to check and it was kind of a non-issue since then.

Damage to the epithelial cells from the cornea also called corneal staining heals very quickly so just don't rub your eyes and it should heal in 24 hours.

It is certainly good, though, that both eye doctors and more scrupulous opticians are not trying to further the myth that blue light is going to damage your eyes or cause eye strain, as opposed to simply causing some issues to your sleep schedule.

[@dimeuno]

Through a large portion of my 20's I had an issue where if I didn't go outside and do routine cardio (running/walking) my eyesight would be noticeably blurry at most ranges. Going out for around 30 minutes or more and looking at things at various ranges (from the very near to the very far like distant mountains) tended to result in my vision becoming clear again. Later I started taking a specific multivitamin that also contains some "superfood" concentrates and minerals. For whatever reason I've basically preferred to be housebound for the last 3 years (starting a few months before the whole covid thing), rarely going outside, but when I have to (to put out garbage and recycling) I've noticed that instead of my vision being very blurry like it used to be, it is clear at all ranges. I suspect it had a lot to do with me being chronically malnourished when it comes to certain things in those multivitamins, but otherwise well fed. Edit: Thought I should elaborate on a couple things. Specifically it was after a few days of not going outside that my vision would worsen. The multivitamin is a one a day kind, and not very expensive.

I also take vitamin-C crystals mixed with fruit juice since I think it might benefit the gums to come into direct contact with it (instead of swallowed inside a pill bypassing the gums), C-rich fruits are probably best though. Omega-3 as well, I believe Omega-6 is easy to get in the diet and the human body can manufacture enough Omega-9. I take vitamin-D drops as well since I don't get enough sun daily.

Simon, I thought that children DO see worse wearing glasses hence, Ortho-K, multifocus lenses, atropine, to slow myopia progression. Whereas, if kids do nothing except get more powerful glasses over time - their myopia will worsen?

[@MrSRMatthews]

@@Allan-et5ig Actually two interesting seperate issues/theories. It has been shown that wearing the correct myopic prescription tends to stop the eye progressively getting worse (longer) COMPARED TO under prescribing/not wearing spectacles. Myopia will progress anyway through teenage years as the eye naturally grows depending on hertitage/genetics. Myopia management as you mention correctly is a "new" way of considering how to stem the axial growth of the eye by tricking it by blurring the peripheral vision. This can be achieved with special spectacle lenses or contacts such as the Coopervision MiSight lens. Atropine in a very low dose can reduce the power of the focusing system (accommodation) which again is thought to be a factor in myopic progression (actually perhaps the most effective method of slowing down the progression of myopia) OrthoK is a method of correction of the vision, but without the peripheral challenges of spectacles - again some evidence to show this works well. So... In summary... A massive topic area. Spectacles do not cause a prescription to get worse - infact it protects against some myopia progression (no effect whatsoever on hyperopia (very slight only) or astigmatism).

I was hoping they would cover this completely about blue light: If it was really true that blue light was damaging to the eyes, we would have a blindness pandemic. But not bcoz of our digital devices but because of the sunlight itself. Sunlight has much more blue light than any of your devices. Now, the only factor where blue light affects your body is after sun down. Our bodies are such that we don't expect blue light after sun set. So if you keep feeding your eyes blue light after dark, then your body will think it is still day and your sleep cycle will get messed. That being said, turning on the night mode found on all the devices nowadays is enough. You don't need blue light filter glasses.

[@VVayVVard]

That's a good point. While blue light is very likely to cause retinal damage in older individuals (due to lipofuscin accumulation) digital devices are not going to be the primary source of exposure. Rather, all sources of bright light can (and will) cause this form of damage. Not just sunlight, but molecules in the sky also scatter both blue and UV radiation very efficiently (via Rayleigh scattering) meaning that simply looking up at the sky without orange-ish sunglasses can be more harmful than looking at a digital screen in a dark room (which, of course, is also potentially harmful for older individuals with more lipofuscin). That's probably the reason why we haven't seen significantly increased rates of age-associated macular degeneration in the digital age―after all, more screen time presumably means less time spent outdoors.

If I was gaming for long periods (multiple hours a day) for a few days I'd inevitably end up with significant eye strain/fatigue. Yellow lens "driving" glasses completely alleviated the issue. The fact of the matter is, blue light has a shorter wavelength and higher energy than most of what we see and our eyes just don't filter it as well as colors toward the yellow/red end of the visible spectrum. UV is more dangerous than IR precisely due to it's shorter wavelength and higher energy, so it seems obvious blue light would be "worse" than most of the rest.

It really depends on their age, but my best bet would be overcorrected myopia due to excess of acommodation or acc spasms, which in layman terms by extension means they had their "eye muscles" permanently set for a closer distance since they never got time to relax, and also that they went to unprofessional eye doctors. If they are older, say 60+, it could be due to hyperopization or even early onset cataract.

A year later, she didn't need glasses at all--she could both read small print up close and see clearly far away and her astigmatism was gone. I think doctors can't find scientific evidence for eye exercises working because they can't find enough people that are diligent over those timescales. But I totally saw it happen. It's not a myth.

I’ve had a long journey of eye issues with my left eye. Specifically when I was 5 I had surgery to help improve my muscles in my left eye because they were weak.

Then a year or two ago I start noticing lots of strain and now my left eye is very blurry. It’s odd, because I went to two ophthalmologists and they both basically said there is no solution, and that glasses will kind of help but my left eye will always see things this way. I hate that I went through all of that just to get to this point where I’m wearing glasses that help just a bit, but it’s not clear at all in my left eye. It’s disappointing to say the least.

Apprentice optician here. From what I've learned: Floaters are usually debris from within the eye flying around in this jelly-like substance called the Vitreous Humor, which holds the eyeball shape mostly. Debris usually gets trapped in that area because the VH is quite thick so the debris can not really find a way to drain itself out and just floats around(most likely that's how the name originated). Considering the age in which the floaters has occurred, the eyes develop over time and presumably swept the debris somewhere outside of your central and peripheral vision. Usually floaters are still in the eye somewhere if no surgical operations were done, perhaps in the blind spot and additional the brain can act to ignore any minute trace of the floaters as much as possible usually by filling in the area with the background more or less, however everyone experiences differently. Not all eye floaters are too detrimental, so the brain practically says whatever to non life-threating floaters. Mostly if the frequency of floaters progresses and what causes the floaters is severe- that's where the medical professional will step in. I hoped I have helped to some extent, typing online is a bit limited with explanations and I'm giving a macro-opinion on the situation. Good to hear it's not bothering you

Eye exercises can help relax eye muscles, lead to less eye strain or fatigue, and making you feel less strained. They do work.

The big story I heard since I was young was this: your eyes do not get better, they only get worse. If you're wearing glasses, you may need stronger lenses over the years, but NEVER will you need less correction. Once you start wearing glasses (that you really need), you'll always need glasses or other corrective lenses. This is why cataracts were the best thing that ever happened to me. Before, broken glasses meant expense and a long wait before you could function again (unless you carried spares with you all the time, usually impractical). Then I had cataract surgery with the corrective (toric) implants. Now I go buy a pair of reading glasses for a few dollars and don't even need glasses to drive. If you ever have cataracts (and I hope you don't), opt for the more expensive corrective implants; it's the best money you'll ever spend. Not to mention that you'll be able to wear non-prescription sunglasses (prescription sunglasses are a pain in the ass unless you carry a purse).

Vision can and does get better for a few reasons that I can think of. Young children are often naturally far-sighted because the eye isn't done growing yet and its axial length is shorter than where it will be by the time they are adults. So they may end up needing glasses with a plus Rx, and then with age, as the eye lengthens, the amount of Rx needed to focus the light properly on their retina becomes less and less. A counterintuitive case of vision getting "better" is when people experience the first onset of cataracts, where vision is affected but can still be corrected adequately by glasses. Adding plus power to the person's Rx may bring them to 20/20. So if you have a nearsighted individual who's always rocked a heavy minus Rx, the case could be made that their vision "got better" when they leave the office with a less minus Rx than before. In fact, when older patients remark that "actually, my vision seems to have gotten better somehow!" you can pretty well guess cataracts early in their development are responsible for this temporary bout of perceived good fortune. But the core of your sentiment is definitely true: there is no "magic" to vision or the eyes. If and when there are improvements (or more typically, degradation), there is a clear reason for it.

@@gaynzz6841 For starters, the entire medical community disagrees with you on that point. Myopia, hyperopia, astigmatism, and all permutations of such, have diagnostic codes just like, say, heart or gastrointestinal diseases. States vary on the specifics, but in general, at least in the US, it is illegal to sell somebody prescription vision correction without a valid Rx for it. In my state, vision Rx's are valid for, at most, 2 years. And if these facts aren't enough, try going into your nearest DMV with worse-than-20/40 vision and see if they'll let you leave with an unrestricted driver's license. Not only does the medical community agree that common vision deficiencies are actual bona fide medical conditions, but this fact is also reflected in various systems and institutions that we deal with in our daily lives.

[@bayleybrunck8237]

There are MANY conditions for which eye exercises can be beneficial. Of course, not the refractive conditions, but CI is far from the only issue out there that can be improved with Vision Therapy. BV/VT/Vision Rehab is a whole specialty in eyecare. Also, pencil push-ups are not a modern VT exercise, this is dated information.

[@nickb2483]

Absolutely. They are 100% wrong about that!

On the topic of blue light filters, there is an extremely small amount of people who will literally get severe headaches from using them. Yes, USING blue light filters can give you more headaches than not using them. I know this because I am one of them, and I've been googling about this for over 4 years and did not find anything until only a year ago where the first mention of this was a reddit thread where like a handful of people said they have the same issue. So if youve noticed youve started getting weird headaches, try turning off your blue light filter and wait for a few days to see if they disappear.

[@wendyrobertson3899]

My son was diagnosed with Eyeritis at the age of 9. The diagnosis came with some pretty crappy news. The specialist eye doctor said that unfortunately there is no cure, however with steroid drops they can slow the progression and MAYBE he won't go blind in his 40's. At his last eye exam he was told that if he were to go up 1 point he would be declared legally bling. The steroid drops run $650.00 for a 0.85 bottle which lasts 7 days. He's supposed to do 1 drop daily. Without insurance it's impossible to put that kind of money out for 14 drops. Have you got any suggestion on an alternative treatment that we can speak to his eye Dr about? Desperate for help! Thank you

[@macaroni_italic]

Not a doctor, and this is not medical advice, but while iritis is not "curable," it is certainly treatable. Acute cases can pop up and then go away forever after a course of treatment. Some people experience chronic iritis. Is this a chronic case? At the eye clinic where I work, they most often prescribe Pred Forte, which is a fairly cheap and common ophthalmic steroid drop, available in generic form. Of course, an Rx is still needed for this. The aim is to reduce inflammation and quiet the eye(s) down until the episode passes. I would talk to the doctor and tell them that the price of the medication they've prescribed is prohibitive and ask if they could please prescribe a more affordable alternative. If a steroid is all that's needed, Pred Forte should do the trick. If your child's case is chronic, my experience suggests a systemic issue possibly requiring intervention by other medical specialists, likely a Rheumatologist. It's not safe to be on steroids for very long periods of time, and other specialists are trained to properly diagnose and treat cases requiring so-called "steroid-sparing drugs" such as Methotrexate. This may be an avenue to discuss with your child's eye doctor.

[@andresaldana6163]

Not to make light of your situation, but it’s kinda funny how an average person could hear iritis and think it would spelled “eyeritis” because it’s a condition pertaining to your eyes. It does specifically refer to the iris though. Another name is uveitis.

[@northwolf7433]

Thanks for sharing this : ) I have only one question as a computer scientist. How computer screens affect human vision? Can a professional like me save eye health and vision after years. I'm a relatively young person who tries to care about personal health

[@youraftermyrobotbee]

Ooh, I have this one! The experts in the video are spot-on when they say blue light will not alter your vision. However, the "eye strain" that can occur as a result of screen time is a result of two factors- not blinking, as mentioned in the video, as well as consistent near focus. Our eyes actually default to focus on distant objects and focusing on near objects (computers, phones, etc) over long periods of time strains the muscles. This cannot actually damage grown adult eyes (but it is a leading factor in the myopia epidemic among children!), but will cause eye- and headaches, the same way that over-exercising any muscle will make it sore. Aside from preservative-free hydrating drops to mitigate the dryness caused by not blinking, a pair of low-power readers (+0.75 or lower) for computer use can lessen the strain as it moves the center of focus for the eye closer. This is actually the only legitimate form of "computer glasses." Paying out the nose for yellow tinted glasses is bogus.

I had 20/15 vision until last year. My vision was worse during my last two pregnancies. It didn't return to normal after my last baby! So now I only have 20/20 vision. I do wear glasses at night time for driving to get me back to my beloved better than "perfect" 20/15 vision.

[@ibghxr]

7:34 I remember reading somewhere a while ago that there was evidence of treating farsighted people or whatever by having them not use glasses at all. I think it also suggested that wearing glasses contributed to the degree of farsight

[@brodylockwood14]

That's true, once you start wearing glasses, it makes your eyesight worse without them. But my eyes were so bad that not wearing glasses would never correct them.
