Tinted Sunglasses

Trading sunglasses is more than just a style statement. Protection from harmful ultraviolet (UV) light is essential to prevent possible damage to the lens or retina of the eye. There is an ever-increasing scientific apprehension at the enlarging size of the ozone hole and the lessening of the ozone layer. The suns UV light, without this protective filter now exposes us all to greater risk. A tint alone on a pair of spectacles will not block UV rays. All it will do is put your eyes in the shade allowing your pupils to dilate more and let in more available light which equals more damaging UV rays. Tints work by filtering light and each tint filters light differently. Light to medium shades are good for daily wear. For bright conditions and outdoor sports, darker shades are more appropriate. A tint alone only helps in reducing glare and improving visibility.
Tints are helpful in enhancing contrast, reducing glare, reflecting bright light or improving visibility on hazy or overcast days. Sodium Yellow provides excellent contrast and depth perception in low intensity light. This is a great tint for skiers and shooter on overcast days.Grey is a neutral, general-purpose tint, popular with golfers, cyclists and runners. Grey does not enhance contrast. Brown provides good contrast in hazy sunshine. Brown is also suitable for anglers, sailors, skiers and in other sports where there is high-glare. Green is a neutral, general-purpose tint that provides some contrast in low light and can help reduce eyestrain under bright lights. It can soften harsh bright light to relieve eye strain, meanwhile still give you 20/20 visions.
You can also specify the percentage of darkness; just enter that percentage in the order comment field. The available tints are straight or graduated. All of our lenses come with UV400 and scratch resistant coating at no extra cost. Different type of lens and prescription might result in slightly different darkness even their percentage is the same.
