This review presents a historical analysis of the develop¬ment of visual acuity research methods, examines in detail the principles of construction of optotypes and charts for visual acuity examination as well as describes the advantag¬es and disadvantages of modern eye charts. Such attention to this topic is justified by the fact that visual acuity is the main parameter characterizing the state of the eye. There¬fore, the study of visual acuity remains one of the most im¬portant methods of assessing visual functions. The generally accepted systems for visual acuity examination, despite the simplicity of their operation, do not have a sufficiently high sensitivity, and the optotypes that are used do not make it possible to adequately assess the functional state of the eye.
