Shopping for Sunglasses

rubber provides better optical quality than the former which is achieved by
glass lenses but they can be quite heavy. On the other part, glass lenses are difficult
to scratch; they provide better optics than plastic lenses in their turn. Make
sure that the lenses filter out the infrared rays from the concentrated sun
conditions.

chromic lenses they darken when exposed to light, also they are called «chameleons»

turn they make your look vague and undetermined. Sunglasses with green lenses facilitate
filtering out blue light and making surrounding things more contrastive and
distinctive. Sunglasses with rose color suit persons who go in for water sports
since such sunglasses provide a good contrast against blue backgrounds.
