Floaters: It sounds as if you have had a posterior vitreous detachment. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. ...Read more

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.

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.

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

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
