results mean age was 41.6 ± 9.2 for the military truck drivers and 43.4 ± 10.9 for commercial truck drivers (p > 0.05). no significant difference between military and commercial drivers was found in terms of driving experience, number of mvcs, binocular va, frequency of color vision defects and cs scores. in contrast, the last ocular examination was significantly earlier in military drivers tha...

We report a functional reflective polarizer that can be incorporated into a compact augmented reality system. The design principle of the functional reflective polarizer is explained and two design examples are illustrated. In the first example, with the specially designed functional reflective polarizer, the transmittance of the augment reality system is relatively high as compared to a polari...

Background and Objectives: Solvents are widely used in industries. Occupational exposure to organic solvents can lead to dysfunction of the nervous system. Since color-vision impairment can be a sensitive and early marker of neurotoxic damage, this study was designed to determine the influence of chronic occupational exposure to organic solvent mixtures on color vision. Materials and Methods: ...

It might be expected that normal trichromatic females would perform as well as normal trichromatic males of the same age when tested with standard clinical color-vision tests that use pseudoisochromatic vanishing designs on neutral gray backgrounds such as the Hardy-Rand-Rittler (HRR) pseudoisochromatic plates and the Neitz Test of Color Vision (NTCV). Here 2966 children aged 6-13 years from fo...

⎯ With the rapid progression of e-learning curriculum, the various needs of content design considerations are increasing. However, little attention was paid to image perception issue related to content design. This study investigated the relationship of field-dependent/field-independent (FD/FI) cognitive style to the perception of color images with respect to colordepth and preference for displ...

BACKGROUND/AIMS Disturbances of colour vision are a frequently reported sign of digoxin toxicity. The aim of this study was to investigate the incidence of acquired colour vision deficiency in elderly hospitalised patients receiving maintenance digoxin therapy. METHODS 30 patients (mean age 81.3 (SD 6.1) years) receiving digoxin were tested using a battery of colour vision tests (Ishihara, AO...

Deuteranomalous trichromacy is the most common form of inherited color-vision deficiency. A modern description of its cause is a single abnormality: the normal middle-wave cone photopigment (M) is replaced by a shifted middle-wave pigment (M) that is shared by all deuteranomalous trichromats. This explanation, however, fails to account for the individual differences in color vision observed eve...
