SAN DIEGO — Night driving vision was “greatly improved” in patients wearing spectacles with wavefront-guided lenses, according to a recently presented study.
Ophthonix’s iZon lenses “improve a driver’s ability to identify pedestrians by an average of 330 ms” when compared to conventional lenses, the company said in a press release. That translates to seeing something about 30 feet sooner at an average speed of 55 mph, according to the company.
In a night driving simulator, 30 patients viewed computer-controlled targets in a night driving scenario while either wearing iZon lenses, which included correction of third- to sixth-order aberrations based on wavefront measurements, or conventional lenses that included lower-order corrections for sphere and cylinder.
Ophthonix introduced the lenses at the American Academy of Optometry meeting here, and it plans to introduce the lenses nationally throughout 2006.
