Hi l l am 46 years old l have glaucoma and been on eye drops ten years, although some serve damage my central and Peripheral vision is still very good according to my eye doctor. Last few months l noticed when l am outdoors if l cover each eye with my hand on look in the distance l noticed the vision in my left eye is not as good or as sharp as my right eye. For example if l read the words on a sign 50 or 100 meters in the distance l can still read the words with my left eye but they seem slightly blurry or not as sharp as my right eye, but this is only noticable if l cover one eye at a time not with both eyes. But this is only in the distance, my left eye is just as good as my right and not blurry if for example l am reading the letter on an eye chart ten feet away. l will mention this to my eye doctor when l see him in two months, l think l read its normal to have one eye not as sharp as the other or could this be something to worry about or related to glaucoma , l am 46 years old and dont use glasses could it just be a case of ageing, also l have recently had problems with dry eye from glaucome eye drop[s could it be due to that. Thanks
