How To Tell Blue Light Glasses Are Real?

Blue light glasses, or whether they’re fake?

blue light glasses, or whether they’re fake?

you’ve come to the right place!

here we’ve covered in detail the 5 tests to tell if glasses are blue light. one of those tests can be done before you’ve even bought the pair so you can avoid getting scammed!

There are two types of blue light glasses

• there are two types of blue light glasses:
• daytime blue light glasses:
• theselook very similar to ordinary clear-lens glasses. you could possibly buy a normal pair of glasses and have no idea that they don’t work.

When you put them on

• not all blue light glasses live up to their promises — but these do, and you can see it for yourself.
• when you put them on, that glaring blue on your device transforms into a mellow amber.
• i want to add that my glasses usually "reflexes" with a purple blue-ish color and when i wear them, i see a heavy color difference in the screen, from blue to "yellow".
• the seller at the store told me that it might just be anti reflex and color distortion, and not proper blue light filtering.

Blue filtered lenses

• blue filtered lenses: these lenses actually block blue light.
• as a result they will look as though they are tinted yellow.
• everything you see through them will be tinted yellow.
• a lot of golfers swear their vision is higher contrast and brighter with these lenses (though when you actually measure the luminance level through these things the opposite is found to be true).
• some people with retinal disease seem to like these filters too.
• their is no concrete evidence they actually do anything though.
• it's most likely placebo affect or personal preference on these cases.

Blue block ar coating

• blue block ar coating: this is the new popular thing that everyone wants.
• this is probably what you have.
• it is a anti-reflective coating that reflects light on the blue end of the spectrum.
• they are clear but reflections on the lens look bluish.
• they don't block all blue light, just a very, very small percentage of blue light (enough to call them "blue blockers" but not enough to make it look like you're wearing yellow shades).
• tons of patients and doctors swear by it and feel like it reduces eye strain when on the computer.
• but there is no evidence it actually does anything.
• at most, there was a prestigious study that suggested they might improve your circadian rhythm and help you sleep at night but that theory has since been debunked.

UV ar coating

• uv ar coating: this is a type of lens coating that blocks ultraviolet (uv) light rays.
• because uv is adjacent to blue light on the electromagnetic spectrum many people don't distinguish between the two or flat out confuse them with one another.
• this means less skilled and knowledgeable optical staff will call uv blocking coating "blue blocking", or will believe blue light causes damage the same way uv does.
• uv actually is a well known carcinogen and is believed to contribute to skin and lens damage over time.
• it essentially ages you.
• in theory you can test a uv coating using a uv pen, but since uv is invisible to the nacked eye you won't be able to tell if it's working unless you use a special device or filter to detect the uv light.
• i would recommend uv coating, but i wouldn't claim that it will make a noticeable difference in your vision or help you do computer work (computers shouldn't be outputting any significant uv anyway).
• furthermore, your eyes have a natural way of blocking most uv rays so i wouldn't claim that you're ruining your eyes by not wearing uv blocker.
• at any rate, most quality ar coatings and contact lenses include uv blocking anyway and polycarbonate lenses (which are the ones advertised to be thinner, lighter, and impact resistant) naturally block uv even without a coating so odds are you have uv protection in some way or another even if you don't realize it.

Blue light test and UV tester device

• the thing is, today i went to a glasses store looking for a new frame, and they did the typical blue light test (with the laser pen) and surprisingly, my glasses didn't pass it.
• later i went into another store and again, my glasses didn't pass, but right after that, they took an uv tester device (can't find it online, but it looked more professional than the pen) and my glasses passed the test perfectly, the seller quickly got embarrassed and took away the glasses.
• so now, i don't know if they were trying to trick me with the pen scam, or if my glasses aren't blocking blue light properly.
• to add on top of this, it is likely that the wavelength of the first light they were using was outside the range of your current coating.
• if your coating only blocks up to 420nm and the light is 460nm, then it will shine through.
• the second light would probably have been 380-400, and been blocked

UV is not blue light

• just adding to what has been said already, uv is not blue light.
• nearly every ar coating blocks uv.
• only a few coasting block “harmful” blue light.
• the fact that this optician didn’t know that means that he doesn’t know what he’s selling.

Blue light glasses

• blue light glasses (sometimes called blue light blocking glasses) are glasses that contain lenses specifically designed to reduce the amount of blue light that reaches the eye.
• these lenses filter blue light rays to help prevent them from entering your eye and causing potential damage.
• usually, blue light lenses have a slight yellow tint (to counterbalance the blue light), but you can’t usually notice this.
• while blue light blocking glasses are effective at reducing the amount of blue light that enter the eyes, there is no current research to suggest that this can improve or protect the health of your eyes.
• put simply, there is no scientifically-proven benefit of wearing blue light blocking glasses for your eye health.

Many brands don’t block much blue light at all

• however, you need to be careful where you buy blue light glasses, because many brands don’t block much blue light at all.
• at best, most are inconsistent in the light they actually filter.
• if you’re simply looking to block blue light and don’t suffer from migraine attacks or hyper light sensitivity, then a good quality pair of blue light glasses may be of some help.
• if you want to block blue light because you’re concerned about digital eye strain, then you’re probably better off to save your money and give your eyes frequent breaks from screen time.
