  • Title: [Physiological mechanisms of the etiology of visual fatigue during work involving visual stress].
    Author: Korniushina TA.
    Journal: Vestn Oftalmol; 2000; 116(4):33-6. PubMed ID: 11031876.
    Abstract:
    Physiological parameters of vision were studied in three professional groups (a total of 1204 subjects): microscope operators, subjects working with magnifying glasses, and computer users. General and specific features of visual system fatigue formation were identified. Because of complete (in microscope operators) or partial (in subjects working with magnifying glasses and display users) "deprivation" of accommodation, these subjects develop early presbyopia (at the age of 30-35 years). In microscope operators long strain of accommodation system leads to professional myopia, while display users develop pseudomyopia. The highest overstrain is observed after 4 years of work in microscope operators, after 5 years in magnifying glass users, and after 6 years in computer users.
