Blue light filter?

[PsychDoc]

Spoke to an optometrist yesterday who said that he would recommend always engaging the blue light filter. He suggested that the blue rays lead to cataracts and, worse still, to macular degeneration as you get older.

Just wondering how many of you use the blue light filter and if you've heard anything about any risks of not doing so.

I do auto sunset to sunrise

I am taking my mother to the eye doctor Friday for her macular degeneration check up, so I'll try to remember to ask this question.

Medical experts says your optometrist is wrong.

First of all, Blue light IS NOT ultraviolet light. Even the link you posted seems confused by it, listing the effects of UV light and wrongly attributing it to blue light.

Second, LCD screens DO NOT emit UV. So slapping on a blue light filter on it will do nothing other than make it look redder. OLED screens emit blue light, but not UV, because these things are made of plastic and UV causes plastic degradation. They have been specifically engineered to emit as low a level of UV light in order for them to last longer than a few weeks.

Third. Even if your OLED screen emits a small amount of UV, the flourescent lamp that you turn on at night and you see everywhere has higher levels of UV light emission than your phone screen. So unless you plan on wrapping your lights in a physical blue light filter like red cellophane or something, using a blue light filter always does nothing to help or harm you.

Fourth, the only reason for using blue light filters is just so that late at night, when you're in bed and there is no other light source to drown the light coming from your phone, you want to decrease the effect on your circadian rhythm so you get to sleep properly.
