Because brightness is linked to daylight and room light, it should be raised in the outside for precise vision, but indoors, a high degree of brightness can harm eyes and even cause headaches after a short period of use.

When comparing males and females, it was discovered that females had a higher rate of occurrence of practically all symptoms. This gender disparity could have been exacerbated by psychological or physical concerns. Males had a higher rate of double vision, frequent blinking, eye redness, and weeping than females, while all other symptoms were mostly reported in females.

According to the Brien Holden Vision Institute, by the middle of the century around five billion people, or roughly half of the world's population, will be nearsighted. Especially in industrialized countries, the number of nearsighted people has risen rapidly in recent decades

Asian countries have above-average rates of nearsighted children and adolescents. For example, after World War II, about 20-30% of 20-year-olds in Hong Kong, Taiwan and South Korea were nearsighted; today the figure is more than 80%. In China, four out of five young people are now nearsighted. In other Asian countries, the rate is as high as 95%. In Europe too, about half of young adults are nearsighted.

there was a jump in the number of people with short-sightedness when they compared participants born between 1965-1970 with those born between 1939-1944 – going from 20% of the population having myopia to nearly 30%. They also found that a greater number of people were developing short-sightedness in adulthood.
