New Yorker Electronics is a franchise distributor for Vishay Precision Group and offers its full line of foil technology products including Foil Strain Gages, Bulk Metal[R] Foil Resistors, Strain Gage Instrumentation, Current Sensing Resistors and PhotoStress stress detection.
In addition, a photostress coating polymer reference sample (PS1, Vishay Precision Group, Heilbronn, Germany) with known elastic modulus was used to calibrate the mechanical measurements [1].
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 recovery test was found to be prolonged in almost all cases for white light between 25 to 110 seconds.

Martin A Mainster (PhD, MD) from the Department of Ophthalmology at the University of Kansas Medical Center discovered that brighter light sources increase "scotomatic glare," known more commonly as Photostress. Photostress occurs because it takes time for the eyes' visual sensitivity to recover after they are exposed to brilliant light flashes.

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.
