Long before they were cool, tinted lenses were practical: a way to hide your expression, to rest your eyes, to look at bright snow without going blind.
From useful to iconic
Cinema made them glamorous. Suddenly every film star wore a pair between takes, and every photograph of them did the rest.
Why we keep buying them
They change a face more than any other accessory, they are cheap enough to lose, and they make every summer photograph look like a better summer.
Choosing a pair
Match the frame to the opposite of your face shape, and the colour to the clothes you wear most. Then buy a second pair, because you will lose the first.
