What type of lenses caused that scarring? Improper fit?
Rigid gas permeable lenses can loses their coatings, and allergies/sensitivities to the preservatives in most cleaning solutions can develop over time. Both caused me problems, luckily a year of wearing glasses allowed me to recover. Now I only use hydrogen peroxide based cleaning solutions without extra ingredients. Much better, except for global supply chain problems right now....
And the RGP market is so small that sourcing alternative solutions sucks - if Boston doesn't work for you good luck I guess.
