Always follow these rules:

* Never lick your lenses - this can transmit germs from the mouth to the eye. Never use tap water, distilled water or home-made saline solution on your lenses.

* Don't touch the tips of your solution bottles - you could contaminate them. Don't wear lenses while swimming. Don't let cosmetics come into contact with your lenses.

* Clean, rinse and disinfect the lenses every time you remove them.

* Clean and air-dry the lens case, and replace it every three months. Do not boil or microwave it - you could damage it.
