Smoking, diabetes, steroid or statin use and ageing are all causes of cataracts, one of the most common eyesight problems across the world.
Signs include cloudy or blurry vision, poor night vision, double vision, seeing multiple images in one eye, not seeing colours brightly, and sensitivity to glare, such as from headlights or sunlight.
Everyone over 60 should have their eyes tested for cataracts every two years as, if caught early, the cataracts can surgically be removed, restoring eyesight to a great degree.
