Product More Function Details 

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.
