What is the crowding effect? People with amblyopia experience the crowding effect, which is described as difficulty reading a letter when it is surrounded by other letters or contours. For this reason, when testing visual acuity in amblyopes, you may measure a better visual acuity using isolated letters than if…continue reading →

Amblyopia (lazy eye) is the incomplete development of binocular or two-eyed vision in the brain. The most well-known symptoms of amblyopia are the lack of 3D vision (stereopsis) and reduced visual acuity. Notwithstanding, amblyopes also often have other visual anomalies besides poor stereopsis or reduced visual acuity. May also be…continue reading →
