Alpina Nylos Shield White + Red Lens

Extremely lightweight, extremely versatile: Those are the Alpina Nylos Shield sports glasses. This makes it the perfect companion for sports. The Shield version provides a spherical panoramic lens with an enormous field of vision and no frame in the way in the lower area.
The Alpina Nylos Shield is also fitted with a high-quality ceramic lens. It is unbreakable and guarantees 100% UV protection – for maximum safety with the best visibility. The mirroring reflects infrared rays and thus reduces strain on the eyes. Malleable nose pads guarantee 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:

Category 0 = 80-100% VLT
Category 1 = 46-79% VLT
Category 2 = 18-45% VLT
Category 3 = 8-17% VLT
Category 4 = 3-8% VLT
