It is an eye defect that occurs in people over the age of 40. When presbyopia develops, the ability to focus near the eye decreases and people have difficulty seeing. Complaints are in different sizes for everyone. The person needs to wear glasses if they have never used glasses and a second glasses if they use glasses.
Presbyopia is not a disease, but a result of changes in the body due to aging. In Greek, presbyopia means “old eye”.
The lens in the eye has a flair. Thanks to this ability, when the distant objects come close, the shape of the lens is bumped and its refraction increases. When we want to see distant objects, this time the lens becomes longer and thinner. The fibers that hold the lens provide the movement of this lens in the eye. Presbyopia occurs because of the loss of flexibility in these fibers with old age.
Presbyopia is the most important problem of people who have difficulty seeing over 40, get tired while reading and see blurred.
When a person whose glasses number (-1) is nearsighted to 40, +1 will be added to his presbyopia number, so he does not need to wear close glasses. This is actually the reason why patients who used to be nearsighted and who say ‘I see people very well now’ see relatives.
Presbyopia is often confused with hyperopia. This is not a hyperopia, but a different condition.
The cause of presbyopia is that the lens hardens and the elasticity of the fibers suspending the lens is lost.
Rapid adaptation and clear vision cannot be achieved in cases of sudden focus change in lens vision that loses its flexibility.
Symptoms of presbyopia include blurred vision at normal reading distance, keeping the material read at arm length, and headache when dealing with jobs at close range.
Presbyopia can be diagnosed with a simple eye examination. Those who have presbyopia are eligible to undergo an eye examination at least once every 2 years.
Although there is no definitive effective treatment for presbyopia, researches on various surgical methods are ongoing.
If the patients do not have an additional refractive error, problems are eliminated with their close glasses. If they are using glasses for the distant, they can be combined in a single spectacle, using bifocal or progressive glasses, according to the recommendation of your ophthalmologist.
