[Effect of age on visual functions]

The differential color-distinquishing threshold, functional reserves, visual acuity, distance to the nearest point of clear vision and positive part of absolute accomodation were measured in working people in active age. A certain deterioration of these visual parameters with advancing age was recorded, which was practicall manifested by decreased ability for fine distinquishing of details, color and relief, when continuous work at short distance was performed. The greater variations in the functional state of vision at the of the working day in elderly workers require measures to be taken to alleviate work, in conformity with the age characteristics of the visual functions.
