Action point


Yellow-tinted or yellow-polarised night driving glasses may sound like just what you need to reduce the glare and improve contrast from oncoming headlights at night, but experts warn that, because driving at night or dusk already entails limited lighting conditions, any tint further reduces the amount of light transmitted to the eye, and consequently further impairs vision.

The problem is compounded as the yellow tint gives the wearer the impression they are seeing better, when in fact the reverse is actually true. Studies have shown that such glasses actually impair visual performance and retard glare recovery.

Beware promoters who have made unfounded claims for the ability of amber lenses to improve night vision. If glare from headlights is a problem, the first step should be a thorough eye examination, as this could be an early indication of cataracts or other medical conditions.
