temporarily used hydrogen peroxide for my contacts

puts on chemistry hat just because both use peroxide as the active doesn’t mean they’re equivalent.

Beyond neutralizing the peroxide, the other issue is Clear Care is more than just peroxide, it’s isotonic and buffered (it also has a detergent for cleaning but that’s beside the point). OTOH Hydrogen peroxide (as the brown bottle antiseptic) is stabilized with a number of different inactives (could be citric acid, nitrates, etc). The Clear Care label clearly indicates its stabilizer is phosphoric acid as part of a phosphate buffer system.

How do contact lenses react to peroxide that’s citrate stabilized, not pH balanced, not isotonic? Is that really an experiment you wanna try with your eyes?
