What is the purpose of the different color lenses?

Frequently Asked Questions
Lenses are offered in different tints and coatings for a variety of reasons, such as vision enhancement, glare reduction and simply cosmetic appeal. Examples: Glare reduction, works just like a sun glass. Approximately 80% of the visible light is filtered out. Mirror coating is mostly a cosmetic aspect. However some mirror lenses filters out more light than a standard gray lens. This lens type is sometimes called a light mirror coating.

FAQs: Sunglasses, Types of Sunglasses and Buying Sunglasses ...
With so many lenses available, it is difficult to find ones that will protect your eyes if you don't know what each one will do. Blue-blockers block blue light and usually have amber lenses. Researchers are still unsure whether or not blue light is harmful, but these are popular among skiers, hunters, boaters, and pilots. Both polarized lenses and anti-reflective coating cut reflected glare. Polarized lenses in particular are popular with those who play water and snow sports.

Why do the enhancer lenses contain color that covers the pupil?

Welcome to the Global Leader in Vision Care - ACUVUE® Co...
Color covering the full iris (the colored portion of your eye) and pupil ensures natural appearance. This way, there is no "transition zone," where the color stops and your natural iris starts. With enhancer colors, the concentration of color is low enough that covering the pupil will not impact your vision.

This means that the Crystalens can provide sharper vision, without corrective lenses, throughout a full range of vision from near to far and everything in between. Standard (single vision) lens implants do not have the ability to provide a full range of vision. Most people who have single vision lens implants MUST wear glasses for middle and near vision.

FAQs of RGPs- What?s The Deal With Rigid Gas Permeable Lense...
Introduced in the 1980’s, RGP lenses are newer than soft lenses. RGPs have silicone incorporated in their design. Silicone is oxygen permeable, so therefore your eyes will receive plenty of oxygen. In fact, RGPs deliver more oxygen to your eyes than most soft lenses. RGP lenses are generally easier to clean and tend to last much longer than soft lenses. This makes them less expensive in the long run. They also provide better vision, clarity and are more resistant to deposit buildup.

Will my transition lenses change color in a car?

Frequently Asked Questions
Transition lenses do not darken in a car. The windshield filters out most of the ultraviolet light. UV light is what causes the transition lenses to darken. The color of the lens does not indicate the amount of protection. Some glasses with dark lenses may provide only partial UV protection, while a clear lens can have 100% UV protection. We recommend that all glasses, not just sunglasses have 100% UV protection. We can apply 100% UV protection to any lens.

Why is rubber on each side of the paddle a different color?

FAQs
Since 1988, it has been an ITTF and USATT rule that rubber must be red on one side and black on the other. This came about because of the rise in the use of "junk rubber" (the name some frustrated players call long pips and anti-topspin rubber). Players who use vastly different sheets of rubber on each side of their paddle had perfected the art of disguising which rubber sheet they used to strike the ball, and consequently what spin was on the ball.
