Common nearsightedness (physiological myopia) affects about 1 in 4 adults.1
Severe nearsightedness, called high myopia (error of 6 diopters or more), affects about 1 in 6 people who are nearsighted.1
Pathological myopia is not common. The gradual damage to the retina caused by pathological myopia seldom appears before age 20.
