Solar glare control

Though bright light during the day is conducive to good health, uneven levels of brightness in the visual field can cause visual fatigue and discomfort as the eyes rapidly attempt to adjust to these differences.

This feature prescribes a variety of solutions for effectively managing disruptive glare emanating from windows, including shading designs, baffles, controls and dimmable glass.
