Double Vision - I am from Australia - I first experienced double vision last September, 2020, shortly thereafter both eyelids closed - my specialist eye surgeon placed ice packs over eyelids and when removed ten minutes later both eyelids were wide open - a rough in surgery test for MG - Blood test later confirmed diagnosis - if your eyelids didn't close perhaps you myasthenia is not as bad as others - do you experience other symptoms - some people with MG only are affected around the eyes, unfortunately, I seem to have symptoms generally - Mestinon should help but it depends on strength used and in my case and sparky they used steroids as well to surpress the immune system
