Dear student,
In a hypermetropic eye, the light is not bent sufficiently so that it focuses at a point behind the retina. Here a person sees well for distance but near vision is difficult and causes strain. Hence hypermetropic people are called long-sighted.
Farsightedness can be corrected with eyeglasses,contact lenses , or surgery. Eyeglasses are the simplest and safest way to hyperopia correction. Your eye care professional can prescribe lenses that will help correct the problem and help you see your best.
Contact Lenses work by becoming the first refractive surface for light rays entering the eye, causing a more precise refraction or focus.
However, contact lenses may not be the best option for everyone.
Hope this helps.
Thanking you
