Abstract
Important optical parameter of the eye is intraocular light scattering. Straylight can reduce visual acuity, contrast sensitivity. It is one of the main factors for glare, especially for drivers at night, when there is light source some distance away from the fixation point. There are many factors, which can affect amount of light scattering in the eye. To assess the effect of the color of the straylight source on retinal image quality at different light scattering levels, retinal straylight was measured with and without light scattering occluder. Red, green and blue colors were choosed for straylight source. Psychophysical and electrophysiological methods were used to evaluate light scattering effect on perception on different color stimuli. Results show that straylight values are the greatest for blue color with and without light scattering occluder. In measurements without light scattering occluder ratio of straylight values for red and green color are different between subjects. Using light scattering occluder straylight values for green color are greater than for red color. Optical and anatomical factors which can induce these spectral variations are discussed. Psychophysical and electrophysiological methods showed the similar changes in results with straylight values when light scattering were increased.
