Abstract
Способ определения остроты зрения, включающий исследование остроты зрения при предъявлении оптотипов с малым 0,05 шагом при снижении освещенности от 400 до 50 Лк и определение величины приращения функции, отличающийся тем, что исследование проводится в несколько этапов, сначала определяют остроту зрения на белом фоне, а затем проводится исследование при расположении оптотипов на желтом, красном, зеленом, синем фоне поочередно, и сравнивают полученную величину приращения функции δ, отражающую разность значений при предъявлении оптотипов на белом фоне с полученными данными на желтом, красном, зеленом и синем фоне, на основании чего оценивают остроту зрения.A method for determining visual acuity, including the study of visual acuity upon presentation of optotypes with a small 0.05 step with a decrease in illumination from 400 to 50 Lux and determining the magnitude of the increment of the function, characterized in that the study is carried out in several stages, first determine the visual acuity on a white background, and then the study is conducted when the optotypes are arranged on a yellow, red, green, blue background in turn, and the obtained value of the increment of the function δ is compared, which reflects the difference in values when the optotypes are presented on white background with the received data on a yellow, red, green and blue background, on the basis of which visual acuity is assessed.
