How to Choose The Sunglasses?

One thinks of sun damage to skin, at least for us. Yet the threat is great!

Stages of completion

Preferably buy glasses with the ‘CE’ marking, protection from 0 to 4 and 100% ultraviolet (UV).

A very dark glass does not protect from UV rays better, but preserves the strong light. In town, just a shade category 2. At sea, category 3 lenses are more comfortable. Category 4 intensity, is banned for driving.

Avoid glasses that turn many colors on pain of eyestrain. The brown improves contrast, it is good for driving. Grey is suitable for everyday use

Choose a frame off: UV rays reach the eye through the sides.

Some lenses are useful treatments. The anti-scratch prevents them from being damaged and no longer protect too well. Polarized lenses eliminate so-called light reflecting off flat surfaces: perfect if drive a lot.

You wear glasses? You can opt for photochromic lenses that darken and lighten according to light intensity. This is the case with glass transition. And in the interiors, they are clear as regular glasses; outside they darken according to the UV radiation. However, by car, they do not darken well as the windshield filters out UV and these glasses are not enough.
