Who Is Affected by Nearsightedness


Who Is Affected by Nearsightedness

Nearsightedness most commonly begins in childhood (between ages 6 and 12).1 Common nearsightedness (physiological myopia) affects about 1 out of 4 adults.2

Severe nearsightedness, called high myopia (error of 6 diopters or more), affects about 1 out of 6 people who are nearsighted.2

Pathological myopia is not common. The gradual damage to the retina caused by pathological myopia seldom appears before age 20.
