The latest innovation in lens technology.
Since the Uvex Variotronic Shield Sunglasses adjust tinting within a tenth of a second to match changing light conditions, they're ideal for virtually any training ride or race but are especially welcome during the shoulder seasons when cloud dover and conditions can be unpredictable. The Variotronic lenses go from clear (64% light transmission) to shaded (16% light transmission) at the press of a button located at the left temple; alternately, they can be left to adjust automatically like any pair of photochromic sunglasses.
This rapid transition is made possible by E-tint technology, which combines a light sensor with a specifically developed liquid crystal lamination. E-tint powers this electrochromatic technology with a tiny, rechargeable accumulator that gives up to fifty hours of power. The Variotronic Shield Sunglasses also exhibit some less technical but just as important features, including a Supravision coating for anti-fog convenience and scratch-resistant protection. The lenses also block 100% of UV rays and offer additional impact-resistance, and the frames are finished with soft, adjustable nose and temple pads to provide a specific fit.

- Q & A
Great concept but fragile / poor design
- Familiarity: I've used it several times
Both these and the variotronic goggles have a high potential level of convenience. However, while the goggles allow you to vary tint, the glasses only have light and dark grey. Here’s what does not work on the glasses.:
1. The light sensor is situated on top of the glasses. If you have a hat or helmet that occludes the sensor, which will invariably happen, the automatic sensor won’t work.
2. The optical clarity for the lens is inferior to standard high quality lenses. There are shadows and distortions. These were more noticeable on the glasses.
3. Charging cover is ludicrously fragile.
4. Stopped functioning within a few weeks of very light use.
After a couple of weeks, the automatic function stopped working so the main innovation (1/10 sec adjustment to light) was lost. The manual on/off still worked. I think something happened to the sensor. The glasses were study and well built. It also would have been nicer if they were a little lighter.
Fantastic but some haze
- Familiarity: I've used it once or twice and have initial impressions
- Fit: Runs large
Wonderful sunglasses! Unlike my Recon Jet, this one can use like the whole day. Light sensation unit works pretty well. Just some doubts, why there were some small black fragments on the temples? And the lens has many scratch, seems like someone used it already. But perfect product at all.
