1. Wash your hands: Before using the care solution, you need to wash your hands to avoid contaminating your contact lenses with bacteria on your hands.

2. Soak the lenses for at least 8 hours each time to achieve the expected effects. The lenses are immersed in the lens case with 2/3 of the volume of care solution and the box cover is tightened.

3. If you wear contact lenses every day, then the contact lens care solution must be replaced every day. And the used ones must be poured out and cannot be reused.

4. If you don't wear contact lenses every day, keep the lenses in the care solution on the days when you don't wear contact lenses, and replace the full-function care solution every 3-5 days (if they are not replaced for a long time, bacteria are easy to breed in the lens case). If the contact lenses have not been worn for a few days, clean, rinse, soak and disinfect the lenses carefully with care solution one day in advance before you can use them with confidence the next day.

5. The care solution can only be used for 3 months after opening the cap.
