Hey everyone! I started this thread back in mid-May because I was wondering why my green laser didn't appear to be as bright as I thought it would be. I think I may have come across a major reason for it: https://enchroma.com/pages/deutan-test-result?v=2&lv=3&l=87.5&m=0&s=100
In case the link doesn't work, it's the result of my taking a free online color blindness test. It shows that I see 100% of blue, 0% of green(!), and 87% of red.
I'm not so sure about the 0% on green since I can easily see a green traffic light, and I can certainly see my green laser, especially when the beam hits something rather than just shining it at the sky. It surprises me that I'm able to see it at all since a laser's color is purely the color it is. If I have 0% green perception, why can I still see it?
EDIT: I just came across another thread here about color-blindness that is very interesting: https://laserpointerforums.com/threads/colorblind.61253/
Whatever the case may or may not be, posts on LPF are not going to change, determine, or prove anything at all. The lasers are what they are and your vision is what it is.
Best advice is get you eyes investigated by a Board Certified Ophthalmologist MD or a Retina specialist to find out what is what with your color vision from a qualified eye MD/professional.
"Most people who have color vision deficiency are born with it. This is because the most common types of color vision deficiency are genetic, meaning they’re passed down from parents.
Color vision deficiency can also happen because of an injury to the retina (the light-sensitive layer of tissue in the back of the eye), the optic nerve (which connects the eye to the brain), or the brain itself. Some examples of injuries that can lead to color vision deficiency are:
Retinal Detachment (when the retina is pulled away from its normal position at the back of the eye)
Eye injuries caused by lasers
Some kinds of brain tumors — especially ones that affect the optic nerve or put pressure on the brain
Radiation treatments
Color vision may also get worse as you get older — often because of cataracts (cloudy areas in the lens of the eye)." From: https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/color-blindness
