Roslavtseva-Kolen Localizer of Light and Color Sensation (A. V. Roslavtsev, 1899-1965, Soviet Ophthalmologist; A. A. Kolen, Born in 1893, Soviet Ophthalmologist)

Roslavtseva - Kolen localizer of light and color perception is a device for studying visual fields in persons with reduced visual acuity up to light perception, which was developed in the USSR in the 20th century.

The author of this device is the Soviet ophthalmologist Alexander Vasilyevich Roslavtsev (1899 - 1965). He was one of the first researchers in the field of ophthalmology, and his work was aimed at studying problems related to visual fields and color perception.

Another author of this device is Alexander Alexandrovich Kolen (born in 1893). He was also a famous ophthalmologist, and his work was devoted to the study of problems of color perception and color perception.

The Roslavtsev-Kolen device is designed to determine visual fields both in conditions of normal vision and when it is reduced to light perception. This device allows you to examine color vision and determine its disorders.

Currently, this device is used in ophthalmology clinics to diagnose various diseases associated with visual impairment and color perception.

Roslavtseva-Kolena localizer of light and color perception

**Alexander Vasilievich Roslavtsev** (1897-1926) and **Andrei Aleksandrovich Kolenko** (born May 18, 1873) are Soviet ophthalmologists who, in their research, identified a unique device that allows them to identify the presence of color and light perception disorders.

Roslavtsev and Kolenko began their work on studying the characteristics of color perception in the first half of the 20th century. They conducted experiments on patients with incurable eye diseases, discovering disturbances in their color perception. These
