Material and methods
As the result of Internet screening visual acuity and color perception tests named " I can see.." in 10 021 children from randomly chosen schools in Poland in the year 2002, the group of 1002 children was chosen. In this group, the subjective and objective refractive error examination was taken as well as the visual acuity test, color perception with the use of Ishihara tables and full ophthalmologic examination.
