Did you know that the vast majority of car accidents happen at night and right before dawn? A lot of that has to do with glare and the problems with vision many people experience. Maybe that’s the reason these driving glasses are selling by the truckload. NightGuide HD promises to reduce night driving glare and eye strain, and it will dramatically improve seeing at night during snow or rainy conditions. It lets you see enhanced color, is durable, lightweight and is fully equipped with polarized lenses. Unlike clip-ons it protects your eyes from all sides, and you can just slide it over your existing prescription lenses if you already wear glasses. Whether driving, reading or golfing, these versatile glasses make seeing a whole new experience.
