Abstract
There are three principal reasons for adopting magnifying loupes for operative dentistry: to enhance visualization of fine detail, to compensate for the loss of near vision (presbyopia) and to ensure maintenance of correct posture. The wearing of loupes is becoming an accepted norm amongst qualified...

Abstract
The functional status of the visual analyzer was studied in professional users of video display terminals (VDT) in relation to the type of displayed information. It was shown that irrespective of the type of displayed information, the VDT users developed visual fatigue over time. With unidirectional...

Abstract
For much of the 19th century, even after the discovery of the ophthalmoscope, the diagnostic clinical signs and the identity of primary optic nerve disease were confused and inaccurate. Amongst many contributions aimed at clarifying this muddle, those of Wilhelm Uhthoff and Edward Nettleship were of...

Abstract
Reduced vigilance for peripheral visual targets indicates that OSA drivers have restriction of their effective field of view, which may partly explain their increased crash risk. This fatigue-related decline in attention is predicted by increased subjective sleepiness during driving. These findings...

Abstract
In the total sample all FPI-R scales were appropriate for the study in the inconspicuous standard range. Slight shifts resulted toward increased willingness to make contacts (scale 4, ST 4.2), reduced physical strain (scale 7, ST 4.3) and lower physical discomfort (scale 8, ST 3.7). The size of the...

Strabismus (15)1 2007
Abstract
Dark vergence is a resting position of vergence, measured in a dark visual field to eliminate fusional, accommodative, and proximal stimuli. Dark vergence differs among subjects: the average subject converges to a viewing distance of about 1 m, while the inter-individual range is from infinity to ab...
