The measurement and recording of vision at near test distances


, : The measurement and recording of vision at near test distances. American Journal of Optometry and Physiological Optics 53(6): 314-317

Confusion and misconception characterize the designation of near visual acuities because of the numerous systems in use. Most of these systems do not lend themselves to accurate or easy usage or to comparison with other test distances. Use of the M system, with the actual test distances recorded in meters, is suggested as a simplified system for standardization.

The effects of 10 days of D-thyroxine (T4) treatment on central benzodiazepine (BZ) receptors in the brain and on peripheral-type BZ binding sites in the heart, kidney, and testis of rats were studied. The experimental hyperthyroidism resulted in...

The amount and chemical composition of herbage eaten by dairy cattle under close-folding and rotational methods of grazing. An attempt was made to measure the herbage consumption of both groups of cows on each system of grazing. The dry matter (D.M.) intake of the cows on close-folding ranged from 18 to 27 lb. per cow daily. Under the rotational system the D.M. intake...
