Could a cheap blacklight LED damage my eye?!

Could a cheap blacklight LED damage my eye?

I purchased a cheap keychain UV LED flashlight and have been playing around with it for a few days. I started to wonder whether or not it was safe, and then i noticed my vision seemed worse. Do you think its a mere coincidence that my eyes seem a bit out of focus, and that maybe because I was thinking about it I then realized my eyesight was worse, or do you think the LED could be damaging my eye? I don't look directly at the LED bulb, but I just shine it on things.

Here is a link to the item I bought: https://www.kaidomain.com/webui/productd...

Well the little LED light doesn't specify if it is an actual blacklight. Based on how you are describing it and the picture shows a Violet colored light coming from it... it sounds like it is.
Well blacklights emit long wave UV or also called UVA.
"In general UVA is the least harmful of the UV rays, but can contribute to the aging of skin, DNA damage and possibly skin cancer. It penetrates deeply and does not cause sunburn. "

Too much exposure to UVB is more harmful for your eyes than any of the UV rays.

As long as you are not shining the light in your eye for extended periods of time you should be fine. If you think about it UVA occurs in our sunlight and I'm sure you have been outside before without sunglasses on and nothing happened. In saying that you should really wear sunglasses if you plan on spending time out in the sun because the UVB rays can cause the early onset of cataracts and such growths as pingueculae or pterygia.

Anyways since you are not actually shining it in your eye and your not even really exposed to it because you are shining it on things then everything will be ok.
If you eyesight still continues to bother you then maybe you should see an eyedoctor for an eye exam....its possible you may need glasses or if you already have them then a new prescription.
Hope that helps :)
