Estimating visual fatigue caused by display operations with temperature rise sensed on human eyelids

Estimation of whether visual fatigue caused by display operations on personal computers will be tolerable is very important to keep one´s eyes healthy. Newly described are the mathematical model analyses of temperature rises on the eyelids of each operator and interpretations allied to this matter. Note that the temperature rises of this mode were optically sensed to have been caused by visual fatigue due to visual accommodation change during display operations on personal computers.
