Tom Ford Brianna Pilot Sunglasses FT1338-N01A 58

Category 3 lenses are suitable in most sunlit situations such as in full sun, in mid-mountain, in the city, or at the beach.

They provide excellent sun protection (against UVA/UVB) and significantly reduce glare.

They are therefore recommended when there is massive exposure to strong radiation (mountains, sea...).

It is also the highest category allowed for driving.
