Smoke, Grey and
Grey-Green tint
The most common lens color
Transmits all colours evenly without changing value of color
Light enough not to impair vision, yet dark enough to provide overall protection of glare
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 has been using Dark Grey/smoke lenses for over 45 years.
However some other lens colors can provide sports specific attributes.
Excellent for bright, sunny days
Grey tint is a great choice for water sports because it blocks out the brightest of the suns rays
Dark Amber or Brown
A warmer, slightly brighter lens than the grey.
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
Improves contrast, reduces glare, perserves sharpness.
High Intensity tint for maximum sight performance during low light driving.
Excellent for night riding, overcast, haze, or fog conditions.
The brightness of this lens makes it the choice of many mountainbikers, cyclers, 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
Helps 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
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).

MIRROR LENSES
Good at blocking glare without changing colour perception.
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 LENSES BENEFICIAL?
Flash mirror lens have 100% UV 400 Eye Protection.
Adds an attractive fashionable look that does not hide the underlying lens colour.
Enhances protection by complementing the basic lens colour.
Highly reflective and greatly reduces the amount of light that reaches your eyes.

Do children need sunglasses too?
Sunglasses for children should be one of your top priorities to provide for your child.
Although parents go to great lengths to protect their children's skin from the harmful rays of the sun, we forget that the eyes need to be protected too.
Children tend to spend more time outdoors than their parents, often in places where there is a lot of sun reflection - beaches, pools, and parks.
Excessive exposure to sunlight during early childhood is harmful to the eyes.
The sun can cause sunburned corneas, cancer of the eyelid, cataracts, and macular degeneration, among other problems.
Sunlight contains harmful UV radiation.
The risk for retinal damage from the sun's rays is greatest in children less than 10 years old
, although the consequences usually do not become apparent until well after they are adults.
All children should be taught to wear sunglasses, especially between
10 AM
and
2 PM
, when ultraviolet exposure is the most dangerous.
Children’s sunglasses are not just about the awesome colors and styles available, but to keep them safe against the suns UV rays.
If there is one thing in common with adult and children sunglasses, is that they both provide the same protection to fight against the suns harmful rays.
