A Drive For Optimal Vision

Posted 8/5/2008

Two technologies The DriveWear lens is exclusively a daytime lens designed for driving, though can benefit patients in other activities, such as fishing, as it``s capable of reacting to lighting conditions both inside and outside the car. The lens, which is available in single vision, flat-top (FT)-28 bifocal and progressive designs and now in polycarbonate material, combines Transitions Optical``s photochromic technology and Younger Optics`` NuPolar polarizing technology. The photochromic technology, initiated by both ultra-violet (UV) and visible light, changes into three distinct colors: ►; Green/yellow. This occurs in low-light and overcast conditions, such as rain or fog. The end result: improved contrast and a reduction of scattered blue light, allowing more of the yellow light to penetrate the lens for maximum foveal sensitivity. This, in turn, provides the most useable acuity, given the limited light. ►; Copper. This occurs in regular daylight conditions behind the windshield, again reducing the blue light to decrease glare and allow less light overall to penetrate the lens for improved comfort. Copper enables the penetration of the red light and secondary green light to facilitate traffic and brake-light recognition. ►; Dark, reddish-brown. This occurs in excess light (bright light, full-sun) outdoor conditions, selectively enabling more green light to penetrate the lens to enhance the outdoor experience, while preventing the sun``s rays from overpowering and oversaturating the eye. DriveWear lenses block 100% UV A and UV B light in all three colors. The company``s NuPolar polarizing technology reduces glare in all lighting conditions. Also, this technology allows for the same level of polarization in high contrast, light-tint conditions, such as those in the green/yellow state. The technology combination result: Improved driving safety, reduced glare and improved eye health through the elimination of UV exposure in all daytime lighting conditions.
