Who should use pinhole glasses?
They can be used by anyone who has blurry vision, young or old, except those who require visual correction greater than 6 diopters. There is no upper or lower age limit for wearing pinholes. They can be worn by small school children who develop myopia (nearsightedness) due to exscessive reading or by people in their 40s, 50s, 60s, or older who have presbyopia, the farsightedness which develops with middle age. For people who need only a slight vision correction, the effect of the pinholes may be almost unnoticeable. Generally speaking, the more blurriness of vision a person has, the more noticeable will be the effects of the pinhole glasses.
