Sports glasses, as the name suggest, are used to be worn in the movement, live on sunglasses. But smart designers also developed elaborately kinds of sports sunglasses which can cover the myopic lens for the myyope, so myyope no need to concern about not seeing clearly. Swimming goggles, safety glasses etc. can all belong to this category. So, how to define sports glasses? The sports safety glasses worn during the exercise must be safety (PC lenses), protective (TR 90 frames, both soft and flexible), comfortable (non-slip nose pads and temple tip), nice appearance (suit active wears and leisure wears.)
Usually the lenses are marked with "UV400" word, which means 100% radiation protection.
There are also polarized lenses. Polarized lenses adopt the shutters’ principle, which can filter the parasitic light. Its advantage is comfortable wearing and more clear vision. Especially suitable for driving, fishing and snow mountain climbing.
Magnesium alloy is a green metal frame material. It is with very soft texture, only equivalent to titanium’s 2/5 and aluminum’s 2/3. Its color is bright and not easy to be faded. The advantage is lightweight wearing and looks superior grade.
TR-90 frame is a super tough resin material, imported from Sweden. It’s smooth, flexible, light and comfortable-worn.
Most sports glasses adopt PC lenses. PC lenses, namely space film, which is uncrushable and indehiscent, with 100% security.
How to use and maintain sports glasses?
Use two hands to pick up the glasses and wear; don’t let the lenses touch the desktop, or any other sharp objects.
If the lenses are dirty, except detergent, don’t use any other solutions to clean the lenses.
Polaroid maintenance: avoid water and ultrasonic cleaning; otherwise it will undermine the polarizing effect.
