This discovery had tremendous applications for decreasing light glare at night, polarized sunglasses, camera filters, desk lamps, windows, 3-D motion pictures, and optical devices.
With increasing age, mesopic vision decreases and glare sensitivity increases, hence, older drivers often report visual difficulties during night driving, even in the absence of ocular diseases [ 8].
Presbyopia (loss of accommodation) starts around the age of 40 years and is combined with other changes in the eye, such as decreasing sensitivity to contrast, increasing sensitivity to glare, and lower visual performance [ 15, 16].
These changes lead to decreased light sensitivity, increased glare sensitivity, reduced visual acuity, and prolonged dark adaptation [ 1, 2].
For example glare and decreased contrast sensitivity often affect cataract patients more than expected, especially in extremes of illumination (Rubin et al 1993).
To examine preoperative risk factors for decreased satisfaction and symptoms of glare, halos, and/or starbursts after laser in situ keratomileusis (LASIK).
This increases the amount of light farther from the window and decreases the amount closer, all while reducing glare.
An increase of the average UDI for a typical room up to 71.8% and a decrease of intolerable glare levels (DGP higher than 0.45) down to 12% were the major benefits of the substitution of traditional clear glasses with integrated PVCCs.
Whether at home or at work, glare filters can be utilized to decrease exposure to blue light.
26, 27 Normal visual changes that occur with aging include presbyopia, decreased contrast sensitivity, decreased dark/light adaptation, and delayed glare recovery.
