||Lighting and optical physiological problems of work with data display screens

||Rapid shifting of the field of vision from the screen to a brighter surface area (e.g. window or manuscript) gives rise to a visual adaptation problem. This adaptation can be facilitated by increasing the size of the characters on the screen and having a luminance ratio between the screen and the environment of 1:3 to 1:4. The possibility of improving screen luminance is examined. Glare and its suppression are very important. Problems of presbyopia can be resolved with corrective lenses suited to the various work distances. Other recommendations are made for the distance between the screen and manuscript, and visual fitness examinations.
