Hey everyone!
So, I'm planning to make my own lasers, all at ~250 mW
I have found goggles that I know will work for different wavelengths.:D

My problem arises with the 405 and 445 nm's
I just found out that my dad and maternal grandmother have macular degeneration, and I'll eventually find out if my mom has it. I did some research, and found that people with one relative with MD has a 50% of having MD as well, and I also found that exposure wavelengths from 400 to 500 nm increase your chances of getting MD. :whistle:

My question is, since I don't like sitting behind goggles all the time, if I pointed a 250 mW 445 nm a good distance away, would I still be able to appreciate the beam and dot without risking my eyesight?

Also, should I be safe in the same conditions with a 405 nm? I have one that I estimate is around 100 mW, and I can hardly see the beam, so if I won't see it much more at 250 mW, I won't take that risk.

Thank you!
