As to your two-week contact lenses, you should wash them every time before and after you wear them. Care solution is necessary, but not enough. Wash your hands thoroughly with mild liquid soap first, instead of moisturizing soap. You should put your lens on your palm, soaking in solution, and rub the lens softly and tenderly with your finger tip. Be careful not to touch the lenses with your nails. Rubbing the lens is a must step. No matter what the advertisement claimed the function of the care solution. Rubbing could help remove the protein building up in eyes on the lens. After washing the lenses with solution, put it into lenses case with 70% full of fresh solution. I suggest you to start wearing or taking off your contact lenses from the same side. I always start to wear or take off lenses from my right eye, so that I won't get confused and wear the wrong lens. If you happen to stop wearing the lenses, you still need to replace the solution in lens case ever week to avoid contamination. Beside, once you opened the care solution, you should remember the date you opened it. Any solution can’t be used after three month since it was opened. Hope you enjoy wearing the contact lenses.
