Presbyopia meaning "old person" describes the state where the eye exhibits an increasingly diminished capability to focus on near objects with age.
Symptoms of Presbyopia –
Most people notice are, complexity reading fine print, above all in low light conditions, eyestrain when reading for long periods, blur at near or temporarily blurred vision when transitioning between viewing distances. Many advanced presbyopes complain that their arms have become "too short" to hold reading material at a comfortable distance.
Alike to grey hair and wrinkles, presbyopia is an indication caused by the natural course of aging. It is usually first noticed between the ages of 40-50. The ability to focus on near objects declines all through life.
A delayed onset of seeking correction for presbyopia has been found among those with certain professions and those with miotic pupils. In particular, farmers and housewives search for improvement afterward, while service workers and construction workers try to find eyesight correction earlier.
Presbyopia is the diminished ability of the eye to focus on near objects. It usually develops after the age of 40 and is a normal part of the aging process. Reading glasses are the normal treatment for presbyopia although surgery is becoming an increasingly more common option.
Treatment of Presbyopia –
Presbyopia is not usually curable - although tentative steps toward a possible cure suggest that this may be possible - but the loss of focusing ability can be compensated for by corrective lenses including eyeglasses or contact lenses. In subjects with other refractory problems, convex lenses are used. In few cases, the accumulation of eyeglasses to an existing lens prescription is adequate. As the ability to change focus worsens, the prescription needs to be altered so.
Approximately the age of 65, the eyes have typically lost most of their elasticity. On the other hand, it will still be likely to read with the help of the suitable prescription. Some could find it essential to hold reading materials beyond away, or require larger print and more light to read by. People who do not need glasses for distance vision may only need half glasses or reading glasses.
Adjustable focus eyeglasses correct presbyopia by providing on-demand wide field dynamic focus. Spectacles of this type are currently available only under the trade name ‘Trufocals.’ Alternative eyeglasses intended for presbyopes are static. Modifiable focus spectacles, though, are neither static nor zonal; in its place they suggest on-demand adjustable {sometimes called ‘variable’} focus over the entire lens area.
In order to reduce the need for eyeglasses or reading glasses, some people choose contact lenses to correct one eye for near and one eye for far with a method called "monovision". Monovision sometimes interferes with depth perception. There are also newer eyeglasses or multifocal contact lenses that attempt to correct both near and far vision with the same lens.
Controversially, eye exercises have been quoted as a way to delay the onset of Presbyopia.
