Darkness not only removes light from the scene when youâ€™re driving, it also takes out contrast, leaving a night driver with the bright spotlight cast by the carâ€™s headlights, and any other place where light is cast by streetlights, a full moon, billboard lights, etc. Itâ€™s a light/dark world with no degree of shade or contrast. High-end sports watch maker tag heuer has recognized that the ability to see varying degrees of light and dark can add that contrast and have created a pair of Night Vision glasses to help drivers to see â€“ even when no light is cast. Hereâ€™s how they work: Originally designed to help drivers in the 24 Hours of LeMans auto race, the Tag Hauer glasses amp up contrast by correcting the low-light short-sightedness of the human eye, which only sees about 10% at night. The pale yellow lenses offer constant clear, sharp vision with a very high light transmission rate in order to contrast dark blue and green surroundings without changing color perception. In addition, the lenses are anti-reflective to reduces glare and increase sharpness, taking added strain off the eyes. Other designs include infra red glasses to see better in the harsh light environment of snow or beaches where ultra violet rays and infra read heat are reflected in the eyes up to 80%. No word on pricing, but for those who make living on the road or at the beach or snow (like Ski Patrol), these glasses are easily must have tools of the trade.
The titanium frames come Wide and Panorama, and have anti-slip elastomere arms to keep them on your head.
