Question

what is astigmatism? name the correction lens used?

Answer 1

Answer:

A common imperfection in the eye's curvature.

With astigmatism, the front surface of the eye or the lens inside the eye is curved differently in one direction than the other.

Explanation:

Rigid lenses correct astigmatism by creating a spherical service on the surface of the eye. A third option is Orthokeratology (Ortho-K) treatment. Patients wear Ortho-K rigid lenses for a period of time to reshape the cornea curvature. The correction will occur as long as treatment is ongoing.
