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.
对处于工作年龄的在职人员测量了色辨别阈、功能储备、视力、近点距离和绝对调节的正值部分。记录到随着年龄增长这些视觉参数会出现一定程度的恶化，当进行近距离持续工作时，这种恶化实际表现为辨别细节、颜色和浮雕的能力下降。老年工人在工作日结束时视觉功能状态的变化更大，需要根据视觉功能的年龄特征采取措施减轻工作负担。
