DESCRIPTION
Presbyopia is not a disease, but rather a normal part of the aging process in which the lenses inside the eyes lose their flexibility. The condition develops gradually over the years, causing the eyes to lose their ability to focus on close objects.
RISK
The condition develops in everyone, although it affects some people more than others. It begins in adolescence, typically becoming noticeable around age 40 and often progressing until about age 65. It is not known why presbyopia affects some people more than others.
SYMPTOMS
Blurred vision at normal reading distance
Inability to focus on small type or tiny objects
Tendency to hold reading material at arm's length
Headache and eyestrain from reading
TREATMENT
Presbyopia is treated with prescription eyeglasses, including bifocals and trifocals (multiple lenses with different prescriptions in one eyeglass frame), and contact lenses. Periodic eye examinations are necessary because presbyopia can get worse, requiring stronger corrective prescriptions.
PREVENTION
Presbyopia-prevention research is ongoing. There is currently no way to avoid this condition.
