Easier and more productive study and desk work.
This article is a uniquely optometric public service. Working from an optometric model of vision, the authors collected and condensed extensive information from many professions and scientific fields, developed additional material, field-tested the information, and created an original, easy-to-apply handbook to help the very large segment of the population that does near tasks. Only an optometric model of vision can tell us how near tasks produce a general tightening of the musculature and undesirable changes in visual status, which in turn lower efficiency at near tasks; and that the way to counteract this process is to have minimal obstructions to movement at such tasks (thus, the information on chair and table design, shoes, etc.). Only an optometric model of vision makes us aware of the value of breaks to offset tightening, and tells us when to take breaks, what to do during breaks, and specific exercises to reduce near task stress. Only an optometric model tells us that the lighting which others consider adequate is often excessive and leads to fatigue, and allows us to determine the proper amount of lighting in general and for the individual. And only an optometric model of vision tells us of the value of adjustable arm typing stands. Because of its approach, "Easier and More Productive Study and Desk Work" reinforces the view of optometry as a broad-based discipline which relates vision to all areas of human performance.
