Can phone torch lights damage your eyes

Destiny

Would that damage the retina? We all know the sun's UV can damage eyes but can a phones torch light like if you held it right up by your eye for long periods of time.

  • But any sufficiently bright visible light shone directly into the eyes for long enough is going to cause damage. Flashing the light on an ordinary torch or mobile phone into your eyes for a few seconds or even minutes probably not. Stare at the Sun for minutes or even hours and you could lose eyesight

  • Actually it’s funny but I seem to recall reading a theory that too little UV light can actually be one of the causes of nearsightedness because the eyesocket continues to grow as we age and exposure to UV light tends to help stop this development. The lens in the eye has a reasonably good UV filter in it that  stops the retina from getting a lot of UV light. That said they say that pilots who get more exposure to UV light from flying higher in the atmosphere do tend to get Cataracts  more because the lens is affected by the UV light it’s filtering out.

    generally in terms of your eyesight infrared light is a lot more dangerous than UV. Infrared light will pass right through the lens of your eye to The retina and can cause damage before you’re even aware of it. This is why people who work with furnaces and other redhot materials that produce a lot of infrared light often need to wear protective eyewear

    Just curious. Sometimes I become obsessively curious about something. I believe it's my autism.

    Thanks for your concern that's actually really touching but I'm ok. I fell asleep last night and I was only asking this question because I was curious, nothing more than that.

    Deodorant spray also makes useful self defense

  • Think I'll ping the mods to make sure the OP is ok

    When have lived in rough and anti-social environments, I have carried such flashlights with me, with the intention of inflicting such damage in the cause of self-defence..

  • It depends.. some flash’s can burn your retinas, so I would imagine that lesser-degrees of damage occur, but damage is damage.. so yes as a rule..

    I'm trying to think of a circumstance that would cause this other than some sort of torture - care to give some context?

  • Yes. Not quickly, but yeah.
