• Do have your eyes tested every two years. Children and pensioners should have an annual check up.
• Do read and work in good light. To avoid glare and shadow, make sure that the light falls over your shoulder.
• Do rest your eyes at least every 30 minutes when reading sewing, using a computer or the like, by looking up and focussing at distant objects.
• Do make sure that your computer and television screens are sharply focused.
• Do wear safety goggles whenever you use caustic chemicals, do woodwork, or run power tools.
• Do wear shatterproof sports goggles for games such as squash.
• Do wear sunglasses when in bright sunlight.
• Do wear goggles in chlorinated swimming pools or in any water of doubtful cleanliness.
• Don’t look directly at the sun, as you might be tempted to do during an eclipse; even the darkened sun can cause severe and permanent damage. Similarly, avoid staring at any bright or glaring lights.
• Don’t rub your eye to try to remove a foreign object. Try blinking and washing the eye with cold water. If that fails, see your doctor.
