Presbyopia is not a disease but a vision disorder or, more scientifically, a refraction disorder. As such, presbyopia has three “cousins”: short-sightedness, far-sightedness and astigmatism.
Presbyopia is a normal aging process of the eye and more especially the eye lens. With age the eye lens hardens, loses its elasticity, which makes the eye’s adjustment process more difficult, a process which, normally, allows us to see things clearly close up and long distance.
A person with presbyopia has difficulties in reading or seeing close up.
We are all affected because, at about 45 years of age, almost all of us become presbyotic.
Presbyopia is a normal result of aging.
Presbyopia starts from birth, but its first symptoms are felt between 40 and 45 years of age. At about 45 years old, almost all of us become presbyotic.
Presbyopia gradually develops between its first symptoms and 60 years of age. After 65 years of age, presbyopia is at its peak and hardly develops any more.
A peculiarity: people with short-sightedness suffering from presbyopia are often capable of reading without corrective lenses.
