Presbyopia is an age-related weakening of the eye's ability to accommodate, that is, to focus on close objects. The cause of presbyopia is sclerosis of the lens of the eye, due to which it loses the ability to change its shape and reduce its focal length.
Symptoms of presbyopia:
-
Gradually increasing deterioration of vision when looking at small objects or reading.
-
The need to move text or small objects away from the eyes in order to see them better.
-
Rapid eye fatigue during close-up visual work.
Presbyopia usually develops after the age of 40-45 in people with emmetropia. With myopia it occurs later, and with hypermetropia it occurs earlier.
Diagnosis of presbyopia is based on medical history, age and refractometry data.
Treatment consists of prescription glasses for close work. Persons 40-45 years old with emmetropia are selected with lenses with a power of +1-1.5 diopters, every 5 years the power is increased by 0.5-1 diopters. For ametropia, corrections are made.
Correctly selected glasses allow you to maintain high vision and performance with presbyopia.
Presbyopia is not a disease, it is a feature of the eye that occurs in people at a certain age and interferes with clear near vision. For older people - presbyks - this is dangerous due to the loss of independence, and it is worth giving up reading small texts, doing small handicrafts, knitting or embroidery. In younger people, this problem is less pronounced, but still interferes with everyday life. Presbyopia can be bilateral or unilateral. In the first case, the disease affects both eyes, in the second only one.
