It is better for you not to use Gas Permeable lens solution for your soft contacts because they are not intended to absorb into the contact lenses and they are much stronger than soft lens solutions. It will very quickly ruin your lenses and can give your blurry vision if it gets more serious. Get the appropriate cleaning solution recommended by your optometrist.
I never try it. But i do not recommend you use Gas Permeable lens solution for my soft contact lenses. You'd better buy appropriate cleaning solution recommended by your optometrist for soft contact lenses. Personally, the solution for Gas Permeable lens and soft lenses are different since they are made of different materials and ways. In order to keep your soft contact lenses well, you shall take care of it.
