I\’ve been diagnosed with strabismus when i was 10-13 years old but i didn\’t undergo any therapy or surgery to fix it, now I\’m reaching 20 this year and wanted fix my crossed eye (right). I\’ve tried patching, and it seems to work but I must maintain focus in keeping them both straight but after a while as I lost concentration, it will just revert back. Both of my eye can see clearly and when i look at myself on the mirror, 50% of the time both my eyes will be looking straight. I\’m wondering if it is too late to be cured without the usage of surgery?
