Uvex Gravity Zero glasses

Uvex Gravity Zero sunglasses aren’t simply posh shades for posing in, they’re precision eyewear bristling with mind-boggling technology. Sure there’s an element of clever marketing at play here but nonetheless, it all translates to a superlative pair of glasses and one, in my view, sounding the death knell for triple lens types. They not only deliver a crystal clear view in all conditions but adjust automatically with the light so you can concentrate on enjoying the ride. Despite otherwise excellent design, ours showed a slightly annoying tendency, albeit brief, to mist over under exertion.

The lenses themselves are made from Makrolon-basically a high tech, super tough polycarbonate (shot tested with a steel projectile at162 kph-that’s 102.53 mph in old money), chosen for its optical clarity, absorption of UV A, B & C rays while being unaffected by temperatures ranging between –40 and 100 degrees Celsius. Thanks to a clever, hydrophobic (water repellent) coating that works to the principles of the lotus effect, these self-clean eliminating staining and distortion caused by rain, sweat and similar particles-leaving them out of their protective pouch and other casual neglect has made negligible impression.

A photo chrome structure- an intelligent lens is what enables their seamless adaptation to minute changes in light and works to much the same principle as the latest generation of welder’s darkshields while retaining perfect contrast. This prowess is so subtle requiring several long rides to fully appreciate but has spoilt me to the extent of spurning other glasses. The frames are made from the increasingly popular Grilamid TR90-a polyester chosen for its flexibility, strength to weight ratio and UV resistance. Neon yellow livery might’ve harked back to 1989 but their soft, tactile, yet tenacious qualities keep them firmly positioned-even subjected to spirited green laning and singletrack antics.

Verdict

State of the art glasses that makes tripple lens systems redundant.

Tell us how the product performed overall when used for its designed purpose

There's no doubting the Gravity Zeros are amongst the technologically advanced glasses out there. It takes a little while and a return to more conventional types to really appreciate the standards of optical clarity given the changes in tone are so natural, allowing complete focus on the ride/conditions ahead. Should conditions turn overcast, the lens turns clear, steadily darkening with the sun's increasing intensity. The only slight disappointment was their (albeit relatively brief) tendency for misting over.

Tell us what you particularly liked about the product

Excellent design, fantastic optical technology, durable, yet very tactile frames.
