Dynamic visual acuity tests
WebA method has been developed of clinically quantifying dynamic visual acuity (DVA), the acuity during imposed head motion in the pitch axis. In this method, visual acuity is measured using a computer-controlled projection system during vertical, sinusoidal relative motion either of the optotypes (the letters to be read) or of a servodriven swinging chair … WebDynamic visual acuity declines more rapidly with age than does static visual acuity (Burg, 1966; Reading, 1972a, 1972b). The correlation between dynamic and static visual acuity is generally low--i.e., there …
