Luminance distribution in the visual field is considered as one of causal factors with a significant influence on visual fatigue, especially for intensive and extended Video Display Terminal (VDT) work. The aim of the study was to define visual fatigue of VDT operators for different values of surrounding luminance. Experiments were carried out in laboratory conditions under 3 lighting condition...

Motion visually evoked potentials (mVEPs) have recently been explored as input features for brain-computer interfaces, in particular for the implementation of visual spellers. Due to low contrast and luminance requirements, motion-based intensification is less discomforting to the user than conventional approaches. So far, mVEP spellers were operated in the overt attention mode, wherein eye mov...

Background: This study was done to determine the prevalence of computer vision syndrome and associated ocular morbidity in a tertiary care hospital. Methods: A cross sectional observational conducted on 673 patients based inclusion criteria. The were asked fulfil survey form 3 OSDI questionnaire. Spontaneous eye blink rate, Schirmer’s test 1, tear break up time, refraction performed for these p...

Miopia adalah kelainan refraksi dengan prevalensi kasus tertinggi secara global terutama pada anak usia sekolah. Dalam jangka panjang, miopia dapat meningkatkan risiko gangguan visus permanen dan mempengaruhi kualitas hidup di masa dewasa sehingga perlu mendapat perhatian khusus. Selama pandemi COVID-19, pemerintah telah menetapkan pembatasan kegiatan masyarakat, salah satunya memberlakukan keb...

Three-dimensional (3D) television sets are already on the market and are becoming increasingly popular among consumers. Watching stereoscopic 3D movies, though, can produce certain adverse affects such as asthenopia and motion sickness. Visually induced motion sickness (VIMS) is considered to be caused by an increase in visual-vestibular sensory conflict while viewing stereoscopic images. VIMS ...

tern may possess fusional capacity that allows compensation for small perceived retinal size differences, but when the difference exceeds a certain level, the binocular system is unable to fuse these perceived image differences and may function as binocular inhibition resulting in a smaller binocular than monocular VER amplitude. Our results show that the binocular system may be able to compens...

Three-dimensional (3-D) television sets are already available in the market and are becoming increasingly popular among consumers. The 3-D movies they play, however, induce the negative sensations of asthenopia and motion sickness in some viewers. Visually induced motion sickness (VIMS) is caused by sensory conflict, i.e., a disagreement between vergence and visual accommodation during the view...

The global pandemic caused by coronavirus disease-2019 (COVID-19) disrupted both public and private life for many. Concerning medical students, practical teaching classrooms were substituted with a virtual curriculum. However, how this new academic environment has affected students’ health lifestyles yet to be studied. In study, we surveyed 2,776 students from nine different countries about cha...

Case 1, a 16-year-old Hindu girl, was admitted to hospital on March 14, 1955, complaining of diplopia and turning in of the left eye for the last 10 months. The symptoms followed a wasp sting on the lid below the inner canthus (by the common wasp Polistes habreus). Acute, intense oedema of the lids and conjunctiva lasted for 3 days, during which the eye was completely closed. When the swelling ...
