Alpina Defey Glasses Black/Black Lens
Purchase
Narrow, simply put, good. The modern full-frame of the Defey glasses is particularly well suited for slim faces. Nevertheless, it can be used for many things: Walking, cycling, water sports, eating ice cream, the Defey is there. Soft temple ends and nose pads guarantee a pleasant wearing comfort and a firm fit for all activities.
The mirrored lenses of the glasses reflect infra-red rays, provide 100% UV protection and, depending on the type of lens, offer a tint of cat. 1 to cat. 3. One thing’s for sure: the eyes.
Technologies
UV : 100% UV protection
Mirror : The reflective surface reflects infrared rays
Ceramic : The ceramic material lenses are break-proof and offer 100% protection
Decentered Lenses : Clear, undistorted vision thanks to decentred lenses
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
