I was laying down and stood up quick and my vision in one eye got dark. Why does that happen/?

Worrisome: When standing quickly, the blood pressure can temporarily drop causing dizziness and blurred or dark vision. The visual changes should occur in both eyes. If the vision is changing in only one eye, then I would be concerned about a circulation problem with that eye. See an ophthalmologist for evaluation. ...Read more

Recently diagnosed-son has 20/200 vision in one eye and 20/40 in the other. He is 9 yrs 4 mos old. Can it be corrected? Has had a physical every yr : (

Poor vision: It depends on the cause of the poor vision. Amblyopia (poor vision in one eye) may be due to uncorrected refractive error (your son might need glasses), a congenital cataract, a lazy eye, or some other ailment. He needs to see a pediatric ophthalmologist soon, since glasses might help him see better. ...Read more

IF I have 20/40 vision in one eye and 20/50 in the other do I need glasses?

IF I have 20/40 vision in one eye and 20/50 in the other do I need glasses?

Makes sense: If your Vision has correctable improvement with glasses, why not clear up your visual world. This is particularly helpful for performing distance related activities. If you are otherwise asymptomatic, you are not required to wear glasses. Note that there are driving restrictions to visual acuity that does not meet certain state enforced minimum levels. ...Read more

Can having bad vision in one eye since I was little start to make my other eye worse? What can I do?

Can having bad vision in one eye since I was little start to make my other eye worse? What can I do?

Not to worry: It is an old tale that if one eye does not work well, the other has to work harder. In fact eyes work as hard as they can, all the time. The loss of one eye does not put an extra strain on the other. You of course have to be more careful not to injure the remaining eye but that is not due to the eye working extra hard. ...Read more

Hi doctors, was just wondering what is better vision in one eye called?

No technical term: Vision is commonly a little different in each eye, and sometimes a great deal so (ignoring those whose vision is bad in one eye from illness or injury.). But there is no technical term to describe the eyes of someone with a natural difference between the eyes. It is simply a description: e.g. The right eye uncorrected sees better than the left eye for instance. ...Read more
