Development of visual acuity
Abstract
A hand-held electrically operated instrument has been devised to assess visual acuity by means of the phenomenon of opto-kinetic fixation nystagmus.
An accurate determination of visual acuity has been obtained from an early age, and a graph of the normal visual acuity development produced.
It has been confirmed that adult acuity is reached by 3 years of age.
