Visual reactions in children and adolescents on reading editions of various formats 

At present, 93-96% of the respondent schoolchildren read extraschool literature. An investigation of the impact of edition format on readability has ascertained that due to the uniform distribution of brightness in the field of vision, large newspaper fonts prevents the development of visual fatigue and provides significantly higher performance and quality of visual work as compared with low book fonts. Experimental studies have yielded data on the stability of a near vision point; this phenomenon may be considered as adaptation to a learning process and myopia developing during learning may be regarded as the price of this adaptation.
