Could you guys help me figure out what's up with my old contact solution?

When I first got soft contacts a couple years ago, my eye doctor recommended I use Clear Care contact solution. It's based on hydrogen peroxide, so it's supposed to kill all the little germies that get in there. The contacts go in this special case with little lens cages, then into the solution filled to the fill line. I used it every day.

A couple times, I would try to put in my contacts in the morning, only to find that more than half the solution was gone, and my contacts withered and ruined. There was no sign of a puddle around the case. I mentioned it to my eye doctor, and she had never heard of this happening. She said to cut back to using it once a month or so, so I did.

But it happened again! I follow the directions, I fill to the line, I leave it for the requisite 6 hours, and I wake up to contacts that have wavy edges and sting when I put them in my eye no matter how long I soak them in a regular saline solution afterward.

I checked the Internet. There's no reports of this happening to anyone else, and no number to call Clear Care customer service. I use silica hydrogel lenses (Accuvue Oasys, if that helps.) I'm not going to buy it again, but I'm just so curious.

Help me, Beauty Brains! You're my only hope!
