  • 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
