Choosing the Right Lens Colour & Tint

 

Sunglass lenses, which one is best?

For General Purpose use, the Dark Grey/smoke lenses are the most popular. They do not distort colours, they reduce glare to provide day-long comfort, and reduce ultraviolet (UV) light to a safe level. If you go to an eye doctor for a sunglass prescription, he'll most likely recommend Dark Grey/smoke lenses for general purpose use. The Military have been using Dark Grey/smoke lenses for over 45 years. However some other lens colours can provide sports specific attributes.

 

Lens Tints and Coatings

 

Smoke, Grey and Grey-Green tints:

The most common type of lens colour. Transmits all colours evenly without changing value of colour. Light enough not to impair vision, yet dark enough to provide overall protection from glare. Excellent for bright sunny days. Grey tint is best for bright light situations like water sports because it blocks out the brightest of the suns rays.

 

Dark Amber or Brown lens tints:

A warmer, slightly brighter lens than the gray. Especially good at blocking the blue light commonly found in diffused light such as one might experience on a cloudy day. Brown/Amber can improve both contrast and depth perception, reduce glare and is a good all-around choice if you live in an area with changeable weather patterns. Brown is great for applications where distances need to be constantly judged, like tennis or golf or skiing or other sports requiring acute visual perception and contrast differentiation. Brown is also best for lower light situations, like fishing in the late afternoon or early morning. Brownish tint lens helps highlight the different contrasts in green colours and enhance visual acuity on the golf course.

 

Yellow Lens Tints:

Improves contrast, reduces glare, and preserves sharpness. High intensity tint for maximum sight performance. Excellent for Night riding/driving, overcast, haze, or foggy conditions. The brightness of this lens makes it the choice of many mountain bikers, shooters and cross-country skiers. Yellow enhances contrast by filtering out the somewhat scattered, out-of-focus blue light from the scene. Hunters, pilots, and tennis players find them helpful for this purpose.

 

Rose Lens:

Help block blue light, thereby improving contrast. Offers high contrast and very soothing to the eyes. Improves road visibility. Many people feel that rose tinted lenses are more comfortable for long periods of time than other lenses. Great for computer users to reduce eyestrain and glare.

 

Blue Lens:

Blue-tinted lenses are endorsed by the USPTA for tennis professionals and were provided to linepersons in the 2000 French Open. Blue is a contrast lens and reduces glare from visible white light (such as light reflected from mist, fog, snow, water).

 

The following is a guide for specific uses and the lens colour that provides the best protection for that activity.

 

 

Mirror Lenses:

Good at blocking glare without changing colour perception.

 

What is Flash Mirror?

The wearer perceives no difference in vision regardless of what colour the coating is. Only those looking at the person wearing the glasses can see the colour of the mirror coating. Mirror coatings are generally applied over sunglass-dark lenses. Obviously, a highly reflective flash coating prevents others from seeing the eyes of the wearer.

 

Flash Mirror sunglasses feature idiflect multi-layer vacuum deposition mirror on polycarbonate lenses, which are designed to absorb more light than uncoated lenses and enhance visual acuity using an optical-grade polycarbonate material and superior hard coating. Lens comes with a light mirror finish added to the outside of the lens, but is not completely a mirror look.

 

How are Flash Mirror Lens Beneficial?

1. Flash mirror lens have 100% UV 400 Eye Protection.

2. Adds an attractive fashionable look that does not hide the underlying lens colour.

3. Enhances protection by complementing the basic lens colour.

4. Highly reflective and greatly reduces the amount of light that reaches your eyes.
