Distance vision corrected w/contacts. if i close right eye, left eye distance vision is blurry & when i close left eye the right eye is clear. why?

Blurry vision : If you have astigmatism in the left eye and it is not corrected with toric (astigmatism correcting) contact lenses, that may explain the blurriness. Another possibility is that the contact lens prescription for the left eye is wrong. See your contact lens specialist to help you figure this out.

Depends: From what you are saying. The right eye is clearer fro distance than the left. Reasons could include: 1) right eye corrected for distance and left eye corrected for near (monovision) 2) wrong power contact lens in the left eye 3) a problem in the left eye that is not correctable with a contact lens see your doctor.

Many possiblities: Left eye contact lens may be set to give you more near vision. Left eye may have astigmatism that is not corrected by the contact lens. It may be necessary to have the prescription of your contact lens adjusted. Your left eye itself may have a problem such as cataract, dry eye, allergies, corneal scarring or other problems. Best to see an ophthalmologist for an exam. Take old lens rx wtth you.
