I’ve noticed that I use up my bottle of contact lens solution a lot faster than Marc does, and I finally realized that it’s because he uses a different lens container. His looks like one of these:
The one I’ve been using requires a lot more solution to fill the well. I just went to the eye doctor and got a free case like Marc uses, so I’ve switched to that one for my daily use. I’m now using less than half the solution each night. And since this type of case is inexpensive ($1.99), you’ll make up the cost of the case pretty quickly.
