- samstave 8y agoThis should be a scientifically studied endeavor. Imagine when you can go into a Lasik place and get the UV upgrade.
- war1025 8y agoThe lens of your eye is what filters out UV light. When the lens is removed because of the cataract, there is nothing to block the UV light, so you can see it.
- adtac 8y agowhat is the range of vision without the lens? Is it expanded just on the blue side or do we also start seeing infrared?
- simcop2387 8y agoIt'll probably only expand to the UV side of things, the lens doesn't really filter out IR at all and you can see some of it already without any changes to your eyes. But your eye isn't very sensitive to it, so you have to block out all other light to be able to see anything. edit: quick way to do this https://www.wikihow.com/Build-Near-Infrared-Goggles https://www.wikihow.com/Build-Near-Infrared-Goggles
- delecti 8y agoThe human lens already lets most infrared through. https://en.wikipedia.org/wiki/File:Human_crystalline_lens_OD.svg https://en.wikipedia.org/wiki/File:Human_crystalline_lens_OD... Infrared is everything to the right of 700 on the x-axis, and ultraviolet is left of 400. Our lens already lets through about the same proportion of infrared as most of the rest of visible light. Presumably that means that our retina is just insensitive to it.
- cnasc 8y agoWould the UV damage your eyes or is a question of intensity?
- trhway 8y agoUV do damage because of energy of a single photon enough to break some bonds. It is the amount of damage that depends on intensity. Similar to Monet case, one can get a NIR camera by removing the IR filter in front of typical digital camera.
- Tharkun 8y agoAmbient levels of UV can damage your skin (think sunburns and skin cancer). There is no reason to assume it wouldn't damage your eyes. So wear sunglasses. Off on a tangent: I always wear sunglasses outside. I don't deal well with light, especially when it's bright. Would love to have that particular vision problem corrected, but eh, probably not in my lifetime.
