Description: A lens which is specially designed to control the effects of chromatic distortion or aberration ... An achromatic doublet is made from a pair of glasses, of which one is typically a ...

Last week, Twitter user Gray commented that "Mass Effect 5 better stick to tradition and have an excessive amount of lens flare." As any good sci-fi project with its roots in the 00s should ...

Longer hours of contact lens wear lead to an elevated risk of developing infections, particularly microbial keratitis. It causes pain, redness, and even potential loss of vision.

Dark matter affects how stars move within galaxies, how galaxies build up over time, and how everything in the universe is held together—but no existing tool has directly detected it. While dark ...

The main purpose of the present work was to examine and compare the effect of ultraviolet and short wavelength visible irradiation on naturally aged human lenses. We found that irradiation with ...

Abstract: The objective of this study was to investigate the effect of different visible light transmission through the tinted lenses on amplitude and implicit time a-wave and b-wave cones adapted ...
