I got a pair of Blue Light blocking glasses made from an Optician. When I got home the first thing i wanted to do was this test with my cheap UV light. The lens seemed to not block any of the UV light! Objects would still glow with the UV light going through the lens. I was upset because I thought for sure these glasses don't have UV protection. I took the glasses back and the Optician sent them out to two labs and both tests resulted in the lens having UV protection. The Optician even let me test them in her office with a UV Photometer and lo and behold they were blocking 98% UV! So weeks later I was still skeptical about my new Blue Light blocking glasses so I went to another Optical store and their machine also said they block 98% UV. So after my experience with my new Blue Light blocking glasses, I don't think the UV light test on lens is as accurate as we make it out to be.

Ok Cliff, thanks for that comment of yours! Well first of all let me thank you for watching the video and take seriously the issue. However I think the test may have not been done properly. Let me explain: you said you used "objects", I can assume these objects glows under light right? They took uv light but also can take "white" light, and therefore they will glow. Now for the test to be accurate I recommend you to use what I did; photochromatic lens (transitions, augen, etc) this is very important cause they react only to uv light and they are sensitive to it. Other thing you could use is UV test that comes in some uv lenses. If you can get a cheap "magic pen" it usually comes with lamp. So you can write something in a blank piece of paper and use it to test. Remember that light has to be the closest possible with the glasses you wanna test, so the light won't go through the edges. I've repeated this test with all types of lenses and never faied to me. Remember also to proff first if the light is uv and not any "purple" light. That's why I use the photocrom lens, so this way I can also check if the light is uv or not. Thanks and have a great one.

@@acromax74 I used a bottle of dish detergent and a bright yellow clear ruler that seem to glow well under the UV light. I would really like to try the test with some transition lens but unfortunately I don't have any, if I come across a pair I will try the test you did. You could be right saying my "UV light" is actually a Purple light, I bought it from ebay ages ago, it has more of a Purple glow to it than a Blue glow. Thanks for your informative reply. Edit - I looked for one of those UV marker's but couldn't find one locally

[@acromax74]

Hi there again Cliff. Well depending on where you live, you may find the invisible "magic pen". The tip is white and it looks that what you write is invisible, but when you point uv light to it, it glows and is visible to your eyes. If you live in the US maybe can be found at dollar tree or 99 c stores, or a party retail store. And yes let me tell you the yellow marker is not always reliable so thats why the test failed. If you go with your local optometrist or optician they may have recycled photocrom lenses, that is for people who returned their glasses because they were wrong prescribed or it was an issue with tolerance to this prescription. Those lenses are useless to the optician and normally they are thrown into the garbage, so you may ask them if you can have one and they may give you one for free... maybe if you offer them a dollar or two will be more than enough 😅

@@acromax74 Great information, thanks!

[@therabbithat]

UV light and Blue light are different things, so I'm confused because your post uses the two words interchangeably. Was the test preformed by the optician checking for blue light or for UV? btw blue light is harmless, and blue light blocking is a scam, whereas UV is actually something we would want to block

Yo :) Take any UV light/lamp, i have a 6 inch fluorescent UV reptile tube, and turn it on. Put your glasses in front of it. Hold a mirror in front of the glasses. When you look at the reflection, you`ll see a dark tube behind the lens, then a purple glow where the nose piece is, then a dark tube behind the other lens. If you can see the purple glow in the lenses, they`re not UV filtered. :)

If you do not have the monochromatic lens, but you do have the invisible ink pen, can you test by seeing if the ink shows up while shining through the test lens?

[@acromax74]

Exactly! Thats one option yes. Just remember when you turn on the uv light pen, do it right next to the lens you want to test, just to make sure the uv light doesn't leak through the edges.

[@cherd5343]

[@n.s334]

It's possible to wipe the lens after, right ? ^_^

[@debbylou5729]

So you need that little light. Where do you get that?

[@acromax74]

Hello there, that depends where you live, but basically yes you need either that little uv lamp or a bigger one. Cause you could use sunlight but its very tricky and most likely the test will fail. For sure you can find it in any dollar store or a party retail one.

[@mediacenter3174]

uva uvb?

[@user-yv9ui6co6r]

If my colorless plastic lenses have uv protect That’s mean I don’t need to wear sunglasses ( all types of color plastic lenses ) am I right sir ? The only different between sunglasses and colorless plastic lens is that the sun glasses block white light ? Am I right in the 2 points I said ?

[@user-yv9ui6co6r]

And by the way is this test accurate 100% for checking if there is protect or not ?

[@acromax74]

Yes, that of course if your glasses have UV protection, it doesn't matter if they are clear or not. Sunglasses block white light yes, but not every sunglasses block UV light. Photocrom lens however block the 2 of them, uv and white light.

[@acromax74]

No test is 100% accurate. This is a homemade tip to check if your glasses have UV block or not, but used as I explained is very precise.

[@hubertswigon287]

Couldn't you just check if that marking you made with the pen is lighting up or not?

[@acromax74]

The filter (lens) helps to know if the uv light is passing through, so if it's "lighting" it means the lens does not have UV filter, on the other hand if it doesn't, then is UV protected

[@peacew6]

Why not just shine the uv light through the glasses to the marking you made with the pen. If it still glows, then you know the glasses have no uv protection. No need for photochromic lens.

[@ebaystars]

Cliff Barry mate I SERIOUSLY DON'T agree with your criticism of the above test - if the UV flashlight (bill checker) flouresces something that it ordinarily does not - then it's generating somewhere in the UV spectrum, and that can damage you eyes:- The normal darkening can open your iris a bit more letting in even more UV. Your so-called optican test is meaningless - you didnt specify the equipment or type of test used and any absolute measurements. My feeling is the optician lied to you and misinterpreted a normal photometer (broad spectrum light source) attenuation of the normal glasses as "evidence" that the UV has gone too. Did you get lab results printed by an accredited test lab ? All I can say is that the glasses DIDN'T block one frequency of UV light and the UV flashlight showed you something is totally amiss. Oh , do you really expect me to believe the guy selling you the specs anyway or his chain or his lawyers? Come dude get real -- PAY for a complete test at a real INDEPENDENT test lab. I just bought 20 pairs of cheap glasses here in Thailand and tested them all with varying results mostly very good. For polarisation test hold the glasses in front of a LCD TV or monitor (not your phone) then looking through them at arm's length rotate them thru 360 degrees at two points they should black out (cancel) the polarised LCD light. If you are flying a 'plane check before you fly that the polarised screens in all the avionics are fully compatible with your "polarised" shades. Also in the states there are 10 bucks test cards called QUANTADOSE which test for ABC UV, they are totally reuseable.

[@cliffont]

The first Photometer was a BPI UV Economy Photometer III and the second one is unknown. I think it's the "UV Flaslight" I have that is really more of a fluorescent light than an actual UV light but I could be wrong. I have seen those UV test cards, i'd probably get one if i found one locally for cheap. No paper results unfortunately.

Simple, if I paid for UV protection... it’s UV protected if not it’s not.

[@acromax74]

It is ,but sometimes you get glasses as a gift or found old grandpa-grandma ones and usually they aren't labeled with the UV logo. And it's better to be sure if your glasses aren't recognized trademarks.

[@switchedon9]

I just paid for it but they don’t look like my old ones with the purpley color so I’m making sure, esp since they’re crooked outta the box
