Glad to see someone covering this topic

thanks for the safety tip, many people think UVA 365nm is not harmful, it is for sure especially with all the powerful lights now available for cheep prices.

Very nice and informative video, I’m sure many will appreciate this! Thanks Martin

I agree with the sentiment entirely, but would recommend clear "UVEX" goggles instead of the yellow which preserve color vision for the purposes of viewing fluorescent wavelengths accurately. Also, your glasses if they're plastic will block most of the 365 wavelength and I think some of the eye discomfort is psychosomatic. Not because I think you are crazy, but because I have felt it forgetting that I had my UV goggles on the whole time 😆

Thank you very much for the safety advice. 👍

Glasses being yellow mostly means they block the blue color and not necessarily that they'd block UV, although most do.
Blocking UV is very easy because the wave is so short relative to the colors that we can sea and many transparent materials block it.

Today, almost every prescription glasses' lens you can buy that are from a good optometrist and company, come with a coating that blocks UV.
You can check your glasses the same way Martin does in his video by pointing a UV flashlight through the glasses at something that should glow in UV. e.g. even at paper money bills that have UV glowing markings if nothing better is available.

Hi Martin, very good advice! I had this sick feeling too, this strong UV lights are definitive not good for our eyes, remember all the fuss about the danger of "blue light", UV has a lot more energy.
Be safe, use at least good sunglasses (with CE). Regards Juergen

the flashlight czar! your majesty!!!!

[lifeisahaze]

English is clearly not your first language and you have a very strong accent but your videos are STILL 10 times better than Charles Bridgtec. Thanks for everything you do Martin

My regular polycarbonate safety glasses (clear) block about 95% of the UV from my bright 365 nm light. My cheap reading glasses block about 80% of the UV.

[harrisonstaley]

Any polycarbonate safety glasses should be fine for blocking uv, even clear, untinted ones

[donaldstrader]

Good topic. Since you are doing these videos in English it might make sense to also post links to the USA and UK Amazon websites, especially if they are affiliate links. Thanks for the videos you post.

[dandildarious]

fwiw, most regular prescription bottles are made out of this uv blocking plastic

[self-taught_angler]

You are trying to protect your eyes but shining the light on your skin and especially on your fingers from a close range. It is a cancer risk.

[dany-ce]

Thank you for your video!
But i have one question, which sounds stupid maybe.
I used UV light for a second by shining it at my bed. Not in my eyes directly. The bedsheet was white, so i could see the UV Light on it. Is that bad for my eyes? Can i get damage from that?
Thank you.

On the internet we can find "transparent" and yellow glasses just like you have. What is the difference between them?

[Dr_Mario]

Amber safety glasses are a good idea, not to mention it could help you with seeing certain fluorescence correctly, although you can kind of get away with clear safety goggles made with PMMA plastic, as this thing apparently blocks UV. Some UV flashlights, especially with Nichia LEDs installed, are no joke.

[MassaraGaming]

I definitely have to buy some decent glasses..the ones that came with my flashlight is horrible

[DanielTseng]

I'll try to find some flip glasses with UV protection since I use UV lights a lot to identify uranium glass and sometimes my eyes hurt. Carrying and wearing an extra pair of glasses not only is a hassle but it would look super weird in public 😂. Thanks for the video!

Fortunately the two 'uv' lights I have are either to weak or not exactly 365nm UV.
I will however look into the goggles/safety side as soon as I find an affordable but powerful 365nm flashlight.
Thanks for the warning
