Eyecare Glossary

AKA Lazy Eye. A disorder where one eye sees better than the other and the weaker eye drifts inward or outward, this commonly appears in childhood.

An anti-reflection coating, also known as an AR coating, is a thin film applied to eyeglass lenses to reduce reflections and improve visual clarity. It helps to minimize glare caused by light bouncing off the lens surfaces, which can interfere with vision and cause discomfort. The coating enhances the transmission of light through the lenses, making them appear almost invisible and allowing more light to reach the wearer's eyes for better visual acuity.

This is the watery fluid in front of the eyeball that is clear and contains glucose and other nutrients. It gives the eye its shape and nourishes the cornea and lens.

A common and minor problem where light isn't focused evenly on the retina causes blurry vision at all distances. The terms "toric" or "astigmatism" are frequently used in the names of contact lenses designed for people with astigmatism.
