In addition to genetic factors, decreased light exposure, reading or screen watching at a close range, and highly intensive education are associated with a patient's increased risk of developing myopia. 

Globally, studies show that children who play sports and spend more time outside have a lower incidence of myopia. Moreover, a 2016 study by Torii and colleagues found that patient exposure to visible violet light, in particular, suppresses the progression of myopia and is an effective preventive strategy to control myopia.

In contrast, studies of East Asian youth attending "cram schools," in which children between the ages of 7 and 12 years spend long, competitive days in school, showed a higher rate of myopia compared with similar-aged children in other countries.

Hypertension, coronary artery disease, cardiomyopathy, consumption of more than three alcoholic beverages per day, excessive caffeine consumption, long-term analgesic use, exposure to sunlight in the absence of protective sunglasses, and physical overactivity/overexertion are not known risk factors for myopia.
