High disinfection power and foam cleaning remain, while the fill line on the disposable cup is easier to see, and the lid has been improved for even greater ease of use. Instructions: STEP 1. Place the lenses in the left and right baskets, close the lid, and then rinse the lenses well with this solution from above for 5 seconds. STEP 2. Fill the solution up to the inner line of the lens cup. At this time, do not use too little or too much solution. STEP 3. Put in the lenses and close the lid tightly. Do not shake the disposable cup. After leaving it for 6 hours or more (at room temperature), you can wear the lenses as they are.
