Optical illusions are fun to look at and can tell us a lot about our sense of sight. What are your thoughts on the way the eyes work?

[@Proverbs_24-5]

It's amazing what God created!

[@twnkls]

I find it amazing what we put our eyes through every day with every move ,every action and vision of light, extreme or blunt. What our eyes have seen and what we remember are two different things but...Are they really? Your eyes can hold a lot of information but there is a limit. The brain will hold yours to memory but the eyes is your software. Just my opinion.

[@Proverbs_24-5]

@Austin Hernandez You seem so sure. Btw are you a old earth creationist?

[@nickthegreek_f.t8848]

Guys I once saw the sun for like 2 seconds when I was 2 years younger, and from that moment and so when I look at bright places, I see many red little dots in the same place I saw it. Did I damage my eyes completely? What can I do? It doesn't hurt me in particular it just worries and annoys me. I'd appreciate some help on what to do🙁

[@sihicb4466]

Hi

[@PrimiusLovin]

I remember reading something somewhere like "you actually see the world with your brain, the eyes are just the windows that let the light in", or something along that line.

[@zardpark1096]

PrimiusLovin that's interesting, how do we do that

[@PrimiusLovin]

I guess it's in our nature to do just that, that's who we are.

[@projectnine9433]

I agree. We can still see things even our eyes closed by using our brain, but also by the information stored in our brain given by our eyes. Get my point? 😅 I'm not good at explaining but my brain tells me everything lol

[@Erick-zj1ld]

This is true, eyes using rods and cons convert light into electrical signals (nerve impulses in the form of action potentials) that are then transmitted to the occipital lobe to be translated. The real mystery is does the brain knows what we see?, because all the brain has are billions of neurons and synapses that fire impulses in the way that enables us to define what we see.

[@comfort_rain]

I was taught that invisible light leaves the eye, bounces off the object, returns to the eye then the brain tells you what you're seeing. I can't find that anywhere on the web though. Anybody here heard of that?

[@ankitanand5443]

Beautifully narrated

[@kylebroflovski6382]

Such a masterpiece of nature, perfected over millions of years through the process of evolution. Now used for viewing dank memes over the internet.

[@Rekkonale]

Waiting for the anti-evolution comments.

[@nantzstein3311]

Wondering when will be the time when eyes become a separate intelligent creature of its own. XD

[@desaad1725]

Were they created of nothing, or were they themselves the creators? - Surat At-Tur, verse 35

[@desaad1725]

wow . masterpiece of nature. but God is not mentioned. you are the real ignorance in humanity. just because we haven't seen our creator doesnt mean there is not. get Logic in your head.

[@adamatlas1113]

Nature?!? lol Umm... Nah. It was designed/engineered by an intelligent "entity".

[@telldem1]

I can't stop thinking about my eyes blinking now.

[@nehirpostaci]

[@sachinthabandara7033]

[@healthylifestylle]

We basically see with our brain, eyes just the windows for light or visual to pass. Because mind store all sound and image data and we can see video when we are dreaming. Mind is great

[@iiweely6160]

سبحان الله ما اجمل صنعك يالله

Enjoyed it. Would have liked more detail on what exactly happens from the rods and cones to the image one perceives....

2:58 now I have to blink manually

[@semihcorbaci]

:D Ahahaha, me too

[@b991228]

After becoming knowledgeable on how a camera works you increasingly become aware that there is very little correlation on how a camera and an eye perceive perspective, line, color and tone. The brain is constantly compensating for the inadequacies of the data being received from the eye.

[@photographyguru2135]

Are the visual aid elements able to be used for educational use?

[@moraiis_eduardo]

Eyes are amazing

[@PR-cp6qe]

PERFECT, hope more video like this

[@sidemirror1432]

Proud to be an optometrist

[@Daveyrawrz7]

I got Lasik surgery for 5,000 dollars, have had it for 15 years and I still see 20/20, still have two life time touch ups in case it degrades.

[@chandanboss7525]

Thanks

[@gixellia8455]

The eye does not see; the brain does. It interprets what eyes deliver, called visial-perceptiual skills of the brain.

[@surajtiwari2614]

It is for kids, would have loved details with animation!

[@manus5423]

you don't see anything if you didn't know how to interpret the visual information. Memory is key to understanding the outside world.

[@DennisStevensonMD]

[@scicorner6547]

Evolutionary processes are sooo cool to learn about👏👏

[@timothyayomideogedengbe8295]

This is not about any evolutionary process. It’s video-graphic description of the operation of the sight sense carried out by the eye organ and the brain through the entering of light.

[@jguti860]

No

Blink every 3-5 seconds? Haha, not anymore, NatGeo. I'm in control now.

Honestly I clearly recognised Lincoln's image before your words

[@renuelcruz9065]

Eyes are doing a great job

[@djmoulton1558]

Disappointed you didn't take the discussion further, i.e. to discuss how we don't actually see anything, but rather that we only receive the brain's INTERPRETATION of the world around us, not the reality of what is actually there.

[@doncornell6893]

Do you mean something like virtual reality implemated in front of us that blocks out what's really happening around our planet earth or space?

[@djmoulton1558]

Close, but also warped by our individual mental aberrations.

[@doncornell6893]

@@djmoulton1558 ah yes I see, maybe the aliens are blocking out what we cannot see around us?

[@JellybellyWaffles]

Don Cornell Your mind is capable of creating things called illusions. Eyes receive information send it to the brain and the brain interprets it... Depending on the person they may see things that aren’t there

[@doncornell6893]

@@JellybellyWaffles thay is true, but can you feel these things flying in from outer space fly through your body at night while your laying in bed or do your pores just open 24/7?

[@manus5423]

what about peripheral vision? you can see movement at the edges of your vision, till almost 90 degrees off your center off vision

[@josephl8981]

All of the retina/back of your eye can detect light, it's just not a crisp/focused. An example of this is that you can look at the first word in a sentence and can read ahead only a few words but can see there are many words following.

what app do you use to make videos??

[@LorenzMotors]

Retina display am I rite

[@johnstewart8849]

I spent my career in ophthalmics...when i create a 3-D model of an object, like an apple, the computer needs inputs along 18 different parameters!....your BRAIN is effectively calculating those parameters, from the data sent by the retina, FOR EVERY OBJECT IN YOUR FIELD OF VIEW!! Some it can recall from having previously imaged that object (my dog), but what power! The brain also has hints from its first glance at a scene...it tends to try to resolve vertical orientation of an object first, then to look for straight lines to define edges. BTW: I think there is a better answer to Senile Macular Degeneration than anti- angiogenesis...that approach is shoveling against the tide.

[@daryasisodiya1619]

[@dr.jamesolack8504]

darya sisodiya Don't worry about floaters.....they are not harmful to vision.

👁 👀 Its so weird to keep observing eye blink. The moment we get our concentration into some thing else, we forget that shutter closing and opening. What is the resolution of our eye picture. 4K? 8K?

If the eyes are single to the glory of God, the whole body will be filled with light. "And there were many whose faith was so exceedingly strong, even before Christ came, who could not be kept from within the veil, but truly saw with their eyes the things which they had beheld with an eye of faith, and they were glad." - Ether 12:19, Book of Mormon
