There is a huge difference between this solution and plain solutions! Plain solutions are made of saline and clear care is hydrogen peroxide. The plate at the bottom of the container is zinc and, when it sits for 6 hours, it pulls out one of the oxygens in H202 and leaves you with just H20 (water)! This deep cleans your contacts better than any solution and is hypoallergenic. If you have sensitive eyes, I would recommend the Clear Care. I found out after 12 years of wearing contacts and getting major chemical burns that I was allergic to saline and that was why I have always had such watery eyes. Clear Care has given me so much relief!
