Tinted lenses will not protect your eyes against the damaging effects of UV light.

However, tinted lenses are helpful in enhancing contrast, reducing glare, reflecting bright light or improving visibility on hazy or overcast days.

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. Some tints, such as pink, blue or purple, are purely for cosmetic or fashion purposes and are poor at filtering light.
