• Why does everything seem lighter through one eye and darker through another?


    Why is it that when I look through one eye everything seems lighter, and then when I look through the other eye, everything looks darker?



    If this is something that is new or recent onset, it definitely signifies that there is a problem with this eye. A change in color perception can be caused by many different eye diseases. Cataracts, glaucoma, retinal disease such as macular degeneration and disease of the optic nerve such as optic neuritis or any other optic nerve problem can cause this. Your question does not give any clue as to what the specific problem is. It does however suggest that you should get to an ophthalmologist as soon as possible for an evaluation.
