TR90 SWITZERLAND: A Swiss technology, this thermoplastic is the material used in all of our sunglasses. Its extreme flexibility, durability and light weight make it the perfect material for performance eyewear.
Ultra Lightweight: As with any piece of high-performance equipment, weight is an important factor. TR90 is incredibly lightweight, which contributes to the comfort of our eyewear and the tendency to forget you¡¯re wearing it.
Polycarbonate Lens Material: Polycarbonate is the extraordinarily durable thermoplastic that's used in bullet proof glass, riot shields and astronaut helmets. It's the ideal material for performance eyewear because of its high impact resistance, inherent UV protection and light weight. All of our lenses are made of polycarbonate.
UV Protection: All of our lenses block 100% of UVA, UVB and UVC rays, and harmful blue light to 400nm. These harmful rays are a leading cause of cataracts, skin cancer and wrinkles around the eyes-all great reasons to block them out.
PROS Lots of variety of lenses all 100% UV protection. Can be used for different purposes: - clear lenses (have a very faint violet/pink reflect)- I use it for indoor beach volleyball to protect from sand - light yellow lenses - i haven't found use for it yet but filters blue light so helps increase contrast of an object against blue backdrop, improves night vision - dark black lenses with purple/blue reflect - looks great for outdoor use and the added reflective colour makes it a little - black lenses (polarized lenses) - anti-glare and the best at filtering sunlight, great for fishing - rainbow (the default ones in the picture) - they look a little bit crazy on but would be suitable for snowboarding/skiing purposes
- detachable arms and replaceable with headband - so useful since it was a little too wide for me and this band ensures that it would stay on when I play sports - other bonus accessories - nice to have - lanyard to keep around your neck, extra rubber nose piece, prescription frames, cloth to wipe lenses - high quality much better than I expected, durable lenses despite rough handling/bending
CONS - not a perfect frame cut - a bit rough around the edges but I'm just being picky not very noticeable up close - knobs from the arms that are used to attach to the arms to the frames seem a little fragile and might come off - so switching the band and arms too often might not be a good idea - no lock attachment on the side of the frames so they tend to come out if the frames get stretched - lenses tend to be a fingerprint magnet but there's a cloth to wipe it
Overall love it reminds me of Oakley Radars. Great value for the money! I got it for only $16.
