AIM To determine the effects of change in light conditions on refractive error and visual
functions including visual acuity, stereopsis and contrast sensitivity. METHODS This cross …

Purpose We investigated the effect of luminance on refraction and visual function under
twilight conditions. Methods Twenty young adults (mean age 20.5±0.5 years) without ocular …

Purpose: Previous studies on the effects of yellow filters in the visual performance have
been carried out, presenting discrepancies among the different investigations. Our study …

Background: We aimed to study the optical and retinal modifications that occur after
adapting to different lighting conditions including photopic, mesopic, scotopic, blue light and …

Purpose: To compare the percentages of photopic, high mesopic and dark illumination
conditions in progressive myopic childrens. Methods: The Visual Behaviour Monitor (VBM) is …

The first objective of this thesis was to find out how the background luminance level, spectra
of the background and stimulus, and eccentricity of the stimulus affect contrast thresholds in …
