If your vision is already "Day adjusted" can looking at the sun for even like .25 of a second then looking away cause any permanent damage to vision?
What about really bright flash lights/or the new LED types...
How can you tell if your eye has any bright light related damage?(Aside from going to the eye doctor) Is it safe to assume that if you have 20/20 vision then you probably didn't damage your eyes by the sun or bright lights?
Thanks
