is a lens technology which allows glasses to adapt to the weather conditions. Just as the chameleon changes to blend in with its surroundings, so these lenses adopt various tints to protect our eyes. The self-tinting photochromic lenses react to UV light, which causes chemical components within them to turn towards the source, producing a shading effect. When the UV light source diminishes, the lenses become lighter again. The process all takes place in a matter of seconds — giving you glasses that are always adjusted to match the changing light conditions.
is a coating applied to the inside of the lens. It is not smooth but rough — seen through a microscope it looks quite fissured. This makes it impossible for moisture droplets to form a covering layer, i.e. to mist up the lens, impairing visibility. This could only occur if the humidity level was such that all the fissures filled with water. But before this can happen, the stored moisture actually condenses, keeping the lens clear — no hairdryer required!
Clear, fog-free visibility is something you should be able to take for granted with good sports glasses, but it‘s impossible to avoid splashes of rain and mud in bad weather. Cleaning your glasses is a tiresome chore and in competitive situations it‘s nigh on impossible. But with the new hydrophobic lenses in Alpina‘s Pro Line glasses the job is done for you. The natural self-cleaning effect of the lotus leaf is well-known, and now Alpina has applied the same principle to its glasses. The hydrophobic, i.e. waterrepellent, nanostructure of the lens causes water to form into beads and roll away, taking any dirt with it. Water soluble particles of dirt are dissolved in the water and any non-soluble dirt is simply dragged away as it struggles to find a grip on the fine surface structure of the lens. This not only leaves the lens clean but instantly dry as well.
Twist Fit Nose 2.0:
One of the most important factors in choosing glasses is the wearer’s subjective opinion on how comfortable they feel. A good fit has a lot to do with the glasses’ arms, but also turns on the comfort of the nose piece. And „turns“ is the right word here, because Alpina has come up with a special swivel design for their nose pads. The Twist Fit Nose 2.0 feature is a clever refinement of the existing adjustment system. The pads on the nose piece have always been rotatable, but now their angle can also be adjusted, enabling the wearer to match them to any irregularities in the shape of their nose. With their twin-component design of hard frame and flexible arms plus adjustable Twist Fit Nose 2.0 feature, the glasses are sure to fit snugly to the contours of the wearer’s face.
The articulated arms allow the glasses to be tilted away from the forehead during strenuous ascents and tilted back to reduce draft on the way down. Clear, mist-free visibility at all times.
The combination of hard frame, soft arm tips and nose pads enhances the fit and comfort of the glasses.
Heavily curved lenses in combination with indirect air flow channeling assure vision that is not impaired by draft or fogging.
This Alpina sport sunglass comes in a case. The cases for the Tri models also accommodate their changeable lenses.
