  • Nearsightedness

    Nearsightedness, or myopia, as it is medically termed, is a vision condition in which close objects are seen clearly, but objects farther away appear blurred. Eyeglasses are the primary choice of correction for persons with nearsightedness. Generally, a single vision lens is prescribed to provide clear vision at all distances. However, for patients over about age 40, or children and adults whose nearsightedness is due to the stress of near vision work, a bifocal or progressive addition lens may be needed.

    For myopia of -1 D or less, the estimated crude prevalence was 26.6% i.e. 49.6 million for whom 4.6% i.e. 8.5 million had myopia of -5 D or less.Our initial research suggests that the pupil responds more if these cells have been exposed to a lot of sunlight in the previous few days. That could serve as a proxy for how much dopamine the eye has been producing.
