Product More Function Details 

Sports sunglasses could give an edge to athletes at all levels, including amateur "weekend warriors" who always are looking for ways to improve their performance in the sports they love.But in their rush to try the latest and greatest gear, such as new tennis racquets or shoes, many sports enthusiasts overlook a key factor in optimizing their sports performance-their vision. Excellent peripheral vision is produced from the curved,single-lens geometry.

Polarized Lens Function:                                                             

The lens we mainly choose(two types):

1. PC Lens and its features

- 100% UVA, UVB & UVC protection

- Superior scratches and impact resistance

-Windproof/ dustproof/water proof

-anti fog

 2. Polarized Lens and its features 

-a higher radiation blocking protection percentage: 100% of any radiation up to 400nm that far surpasses the legal  requirements of both the US and EU.

-a lower transmission: only 15% of visible light reaches the eye

-up to 100% protection from reflected glare,and block reflected light from water,snow,road and so on.

-high protection against potentially dangerous “ blue light”

-superior scratch-resistance and high rigidity

-each lens is extremely strong and resistant, withstanding the Drop ball test – a 5/8 inch steel ball dropped onto the lens  from a height of 50 inches—which makes the optical glass impact resistant even at the lowest thickness. Plastic lenses  have a natural impact resistance that is similar in strength to crystal and even more.

-Meets ANSI Z87.1-2003 & CE EN166 High velocity impact safety standards

The frame material we mainly choose(two types):

1.PC frame:

Pc as the name imples to polycarbonate, the feature is free wearing and comfortable, light weight, anti- 

shock, also flexible. but the price is more cheaper than Tr90 material. so it is widely used in the outdoor sport sunglasses field.

 2.Tr90 frame:

This material is more flexible than the PC material: softy, light weight,abrasion resistance,not easy to distort. but the price is much higher than the PC frame. 

these two material has its own advantages,but they also have common function: 

-Open frame design,easy to change lenses

-Superlight and comfortable for wearing.

-Removeable temples to exchange the strap when extreme sports

-adjustable nose piece provide the perfect fit when you forget your wearing it.
