Question

what is long sightedness and how it is corrected​

Answer 1

Answer:

Long-sightedness is when the eye does not focus light on the retina (the light-sensitive layer at the back of the eye) properly. This may be because: the eyeball is too short. the cornea (transparent layer at the front of the eye) is too flat. the lens inside the eye is unable to focus properly.

Surgery to replace the natural lens inside the eye with a multifocal lens implant is now often used as an alternative to laser eye surgery for the correction of long-sightedness. This operation, called refractive lens exchange, is similar to cataract surgery.
