Retinal pigmentation

I am pleased to announce that I finally learned why my eyes are more sensitive to sunlight than the eyes of other people. My optometrist explained to me that our retinas have pigmentation, and with less pigmentation the eye is more sensitive to light. I had wondered about pigmentation in the iris -- which controls eye color -- but I have found in my talks with friends and family that light sensitivity does not really correlate with eye color.
