When sunglasses are made, the lenses are treated with UV-absorbing chemicals to be able to block UV light. Because these chemicals are usually colorless, clear lenses could block light just as well as dark-colored lenses. So why so many lens colors?

Purpose of Tints

Tints filter light in different ways, and some tints do a better job at blocking light than others. Some tints actually enhance colors, while others distort them. Tints have the ability to enhance vision in certain situations. Although you may admire a certain tint color, it may not be the best one for your particular lifestyle.

Uses for Different Tints

Following is a handy tint guide for choosing sunglasses.

    • Gray: Gray is a popular neutral tint that allows the eyes to perceive colors in their purest form. Gray tints reduce brightness and glare. Choose gray for driving and outdoor sports such as golf, running, or cycling.
    • Yellow/Orange: Yellow and orange tints increase contrast in hazy, foggy, or low-light conditions. These tints tend to make objects appear sharper both indoors and outdoors, but can also cause color distortion. Choose yellow shades for snow activities and indoor ball sports. Yellow shades can also be helpful at nighttime as they increase contrast.
    • Green: Green tints filter some blue light and reduce glare while offering high contrast and visual sharpness. Shades of green also tend to reduce eyestrain in bright light. Choose green for precision sports such as tennis, baseball, and golf.
    • Amber/Brown: Amber and brown tints reduce glare and block blue light, brightening vision on cloudy days and increasing contrast and visual acuity, especially against green and blue backgrounds such as grass and sky. Choose amber and brown tints for fishing, baseball, golf, hunting, cycling, and water sports.
  • Melanin: Melanin pigment in sunglass tints is said to protect the eyes from aging changes related to sun exposure.
  • Rose/Red: Rosy tints increase contrast by blocking the blue light. They have a reputation of being soothing to the eyes and more comfortable than others for longer wear-times. They also help with visibility while driving, and seem to be a favorite among computer users as they reduce glare and eyestrain.

Additionally, some tinted sunglasses may help with various eye diseases by increasing contrast. Talk to your eye doctor about which color shade is best for you. Get more of the latest fashion news here.
