on 12/6/2008 I've sold sunglasses for over 15 years. Polarized sunglasses are the best choice since they block reflected glare as well as direct sunlight glare. Try to find brands that produce their glass lenses with a tinted front wafer (lens). those lenses will block more HEV (Hi energy visible) light or Blue Light and provide sharper vision and better glare protection from direct and reflected glare. Glass lenses provide better protection and visual acuity than plastic lenses. Avoid acrylic lenses; they're used in cheap sunglasses. Also avoid designer brands, most likely you're paying for the label. Typically they use standard CR39 lenses which provide minimal protection for twice the cost. In my opinion, the best brand for the money is Reptile. Maui Jim is excellent but a lot more expensive and not any better.

on 8/8/2006 Your sunglasses should have minimal gap between them and your skin, especially at the sides and top. Because your eye is dilated (due to the shade of the lens) a gap at the top will allow a lot of UV light into your fully dilated eye and cause more damage then not being without your sunglasses.

on 11/22/2005 Don't forget to see how high the frames cover at the top. Your eyelids are very fragile to UV exposure and a sunglass that has a "roof" at the top of the frame gives better protection from glare, and stops your eyelids from burning.

on 11/22/2005 Polarized lenses cut out 50 pecent of light (vertical or horizontal). You can tell if lenses are polarized by taking two identical pairs and turning one lens sideways - there will be a blackout! They help you see into water well, too, for fishing.

on 11/22/2005 For general purpose wear, try gray or green lenses, they keep colors natural. Orange or amber lenses work for cloudy days, since they block out blue light. Polarized lenses cut the glare from the snow. Mirror lenses help reduce light in high altitudes.
