The strength of the Alpina Lyron VL sports glasses is their full-frame design, which offers modern style and outstanding protection. This keeps you as safe as possible during sports while still looking good. The Varioflex lens technology is used in addition. It ensures optimum visibility in all weather conditions. The lenses automatically adjust to the lighting conditions (photochromatic). This provides ideal visibility in both sunny and cloudy weather conditions. The lens is made of unbreakable ceramic material and provides 100% UV protection. Malleable nose pads as well as temples with a rubberised soft insert ensure the best possible comfort. Meanwhile, a high-quality folding mechanism keeps the strap in its position.

Visible Light Transmission (VLT)
This is the measure of how much light your sunglass lens lets through to your eye and can be expressed as a percentage, therefore a VLT of 1% means very dark glasses indeed, and a VLT of 100% means all the light is getting through and the lens is therefore a 'clear lens'.
Rather than quote a percentage for each lens they are categorised as follows:
