Adjustable Focus Telescopes for Near Vision

Optometry and Vision Science, 1991
ABSTRACT It is important for clinicians to know the equivalent viewing power and corresponding equivalent viewing distance of the adjustable‐focus telescopes they prescribe for low vision patients. Formulas are presented here to calculate the equivalent viewing power and distance of these telescopes. The optical effects of adjusting a

The assessment of near vision.

Canadian journal of ophthalmology. Journal canadien d'ophtalmologie, 1975
There are many variables in the physiology of near vision, the end-point criteria, the types available, and the measurements made. I have suggested a hard criterion of the smallest print at the nearest distance. This controls the physiological variables and provides repeatable data for the evaluation of vision, accommodation, and binocular function.

A Factor in the Production of Divergence Increase with Near Vision

American Journal of Ophthalmology, 1935
The divergence maximum of 96 pairs of eyes was measured by noting the greatest prism, base in, through which binocular single vision could be maintained when the test object was held 5 M. 50, 33, and 25 centimeters from the base line of convergence. It was found that the maximum possible divergence of the optic axes of the eyes is greater when the ...
