If you use reusable lenses, taking care of them is very important. If you do it properly you'll never have troubles with your contact lenses.
Disinfect your case: Fill each part of your lens case with your disinfecting solution.
Wash: Place one lens in the clean, dry palm of your hand and apply a few drops of your favourite solution. Clean the lens between your 2 fingers, softly rubbing both sides.
Rinse: Rinse with more solution and gently put the lens into your clean case.
Repeat: Do the same for the other lens, then you can close your case and leave your lenses to soak.
