Eyes cannot lie. About our feelings, about our health - and about our age. And since up to 80 per cent of the information we receive from the world comes to us through our eyes, it is vital not to neglect them. The conventional wisdom is simple: wear specs (or contacts) if you have poor eyesight, don’t sit close to the TV, read under a good light, take off your eye make-up at night - and eat lots of carrots. But there is much more you can do to protect your vision, banish bags and keep the eye area beautiful.
