We determined the effect upon accommodative responses of tinted lenses prescribed for the relief of visual discomfort in a group of five long term lens wearers. Static and dynamic responses were measured under four viewing conditions (1) prescribed tinted lens (2) neutral density filter (3) tinted lens of complementary colour and (4) no absorptive lens. While similarity and normality of the mea...

PURPOSE To investigate the possible effect of aspherical or yellow tinted intraocular lens (IOL) on contrast sensitivity and blue-on-yellow perimetry. METHODS This prospective randomized bilateral double-masked clinical study included 52 patients with visually significant bilateral cataracts divided in two groups; 25 patients (50 eyes) received aspherical intraocular lens in one eye and spher...

PURPOSE To observe changes in fundus autofluorescence 2 years after implantation of blue light-filtering (yellow-tinted) and ultraviolet light-filtering (colorless) intraocular lenses (IOLs). SETTING Department of Ophthalmology and Visual Science, Nagoya City University Graduate School of Medical Sciences, Nagoya, Japan, and the Department of Ophthalmology, University of Bern, Bern, Switzerla...

PLoS Biology | http://biology.plosjournals.org This important book relates much the most optimistic treatise on conservation that I have ever read: many would say naively optimistic. I should say from the outset that I genuinely fear that Michael Rosenzweig’s theories and examples are less broadly applicable than he argues. And yet I want to believe that he is right. If he is right, the conserv...

PURPOSE Tinted lenses have been widely publicized as a successful new treatment for reading disorders and visual stress in children. The present study was designed to investigate a variety of visual deficits reported by children who experience high levels of visual stress and perceptual distortions when reading (Meares-Irlen syndrome; MIS) and to assess the improvements in visual comfort they r...

Proper design and appropriate configuration of daylight systems, as the primary means controlling distributing daylight, greatly improve visual comfort reduce energy consumption. Daylight systems are widely used around world, light distribution in interior spaces; residential buildings, vertical windows most common ones. Iranian architecture has been using a traditional system for over centurie...

The endowment effect, predicted by prospect theory, is a robust finding in behavioral decision theory. Extending recent examinations of the underlying processes, we present evidence for differential perceptions of the traded item, with sellers focusing more on positive features and less on negative features, relative to buyers. In experiment 1, sellers and buyers access information of differing...

0= 85° onto a smooth surface, such as glass, possessed a high absorption characteristic of an aggregated structure (Fig. 4.), but diffuse reflection was not present. When, however, a film of 2.7,ug/cm 2 was deposited at 850 onto an aluminum film (16,ig/cm), which had been deposited at normal incidence, a strong decrease in specular reflectivity for the blue was obtained. Both aluminum films wer...
