Almost everyone encounters presbyopia at the age of 40–45. This is the result of a gradual, progressive decline in the eye’s accommodative ability that occurs with age. This condition is irreversible and progresses at different rates in different people.
A refractive error of the eye in which vision is impaired at near distances and may also be reduced at far distances.
Definition: Hyperopia, or farsightedness (low clinical refraction), is a condition in which images are focused behind the retina rather than directly on it. This disorder is caused either by insufficient refractive power of the eye’s optical media or by a shortened eyeball.
A type of hyperopia is presbyopia — an age-related decline in the lens’s ability to change its curvature, resulting in reduced focusing ability.
