Myopia, commonly called shortsightedness, is a condition in which light is focussed in front of the retina, resulting in blurred vision. Nearsightedness is a very common vision condition affecting nearly 30 percent of the U.S. population. 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.
The prevalence rate of Myopia is US is 23.918 % which accounts to 34,119,279 out of 142,648,393 population.A recent population-based cross-sectional study on preschool American children aged 6-72 months reported a myopia prevalence of 1.2% in non-Hispanic whites, 3.7% in Hispanics, 3.98% in Asians, and 6.6% in African Americans.
