Red Light 670 nanometers improves eyes -


Recommended Posts

Good. I have a 660 nm deep red LED and I just got a 680-690 nm one (both "10 W"). Maybe I will do it, why not.

Stefano...I mean, it's probably better for you than UV, but you can still literally fry your eyeballs don't forget.

If I do it with closed eyes it shouldn't be too dangerous. I can always dim my LEDs, I have a CC CV power supply and I can set the current anywhere between 0 and 5 A.

 

Surely better than the nice blue from my 340 nm LED.

I generally try to avoid looking straight into my 850 and 940 nm LEDs, as, of course, they are much brighter than how they appear to me. After a while, my eyes feel "tired", like if I stayed at the beach for an entire afternoon. They probably aren't too dangerous, but still not very wise to look at them.
