Subjects were evaluated at baseline, three months and six months for MPOD (Macular Pigment Optical Density) and markers of visual performance including contrast sensitivity, photostress recovery, and disability glare.
This article will examine new studies showing lutein, zeaxanthin, and meso-zeaxanthin improve photostress recovery time and disability glare.
Photostress occurs because it takes time for the eyes' visual sensitivity to recover after they are exposed to brilliant light flashes.
It also filters short wavelength light to reduce chromatic aberration and light scatter, thereby enhancing visual performance in terms of contrast discrimination and photostress recovery in both normal and AMD patients.

He reported on the significant relationship between levels of lutein and zeaxanthin and their effects on visual function, such as photostress recovery, glare disability and chromatic contrast sensitivity.
One of the biggest problems for older drivers is the brightness of the blue-white xenon HID headlights of oncoming cars, which increases intraocular light scattering, glare sensitivity and photostress recovery time.
Lutein and zeaxanthin can reduce disability and discomfort from glare, enhance contrast, and reduce photostress recovery times.

The study looked at three aspects of visual performance: glare disability, photostress recovery time and contrast enhancement.
