Abstract:
Stray light is a physical phenomenon that degrades visual quality when light scattering occurs in the human eye.It is a main cause of the disabling glare.Stray light originates in cornea,iris,sclera,lens and retina,and these ocular tissues contribute to the total amount of stray light in a normal eye.The light scattering intensity increases when the transparency of any optical element mentioned above reduces.Stray light can be measured by several different methods,but the measurements still lacks a standardized procedure and outcome.Further clinical study is necessary to quantify and standardize the measuring method of stray light.This article aims to introduce the concept,source and clinical significance of stray light,and to provide its advanced measurement techniques and methods.
