摘要
Previous studies of visual “crowding” in children have been restricted to the use of high contrast optotypes. In this study, visual acuity was measured in a group of 30 normally sighted children using high (96%), medium (11%), and low (4%) contrast Snellen charts and isolated letter cards. The crowding effect was found to be less for low contrast letters than for high contrast letters. © 1990 American Academy of Optometry.
