Objective This study aims to analyze the effect of correlated color temperature from LED glare sources on driving performance. The evaluation includes assessing disability visual reaction time and rating discomfort using a standardized scale. Background technology is widely incorporated into various lighting systems; however, impact oncoming car headlamps performance at night-time crucial for road safety. Method Twenty-three healthy young subjects participated in laboratory-based experiment...
The increasing replacement of traditional lamps by LED technology opens the door to research into visual performance under their multiple possible spectral power distributions. correlated color temperature and S/P-ratio are considered parameters characterizing spectrum a light source. lack firm conclusions motivates analysis in this work influence spectrum, which is defined S/P-ratio, on representative night-driving task, reaction time. A two-channel four primaries photostimulator was used...
The purpose of this work is to analyze the interaction between spectral transmittance old-aged subjects, before and after cataract surgery blue light-filtering intraocular lens implantation, power distribution common street lamps, under conditions typical nighttime driving. We analyzed contrast threshold visual reaction time in off-axis vision at different mesopic illumination provided by high-pressure sodium metal halide lamps. Three groups subjects with transmittances participated: young...
In old subjects, the effect on visual performance of interaction between spectral power distribution street lamps and different types intraocular lenses (IOLs) is unknown. Contrast threshold (CT) reaction time (RT) were analysed in off-axis vision at mesopic illumination conditions provided by high-pressure sodium metal-halide lamps, using a Maxwellian view optical system. Four groups subjects participated: 10 young 20 elderly with cataracts same after cataract surgery divided into two...
