It’s unusual, but a person can indeed be nearsighted in one eye and farsighted in the other. There are two medical terms used to describe this condition: anisometropia and antimetropia. Anisometropia is the condition where the two eyes have significantly different refractive (light-bending) powers.

Can you have both nearsightedness and farsightedness?

Yes, your eyes can have such different vision that one eye is farsighted and the other is nearsighted. This is an uncommon condition called antimetropia.

Is astigmatism nearsighted or farsighted?

In astigmatism, light comes into the retina at multiple focus points because of an irregular shaped cornea, which causes blurring. With astigmatism, one or both eyes can be farsighted, one or both eyes can be nearsighted, or one eye can be nearsighted while the other is farsighted.

Which is worse short or long-sighted?

The difference between long and short – sighted people is a frequently asked question. Short – sightedness is by far the most common vision problem in the world. Long – sightedness is a smaller problem in terms of the number of people affected but both affect significantly vision.
