I have had long covid for 2 1/2 years. Like everyone, it has wrecked my life. I have had blurred vision throughout and can only read for 10 to 15 minutes. Worse was double vision. Had to give up my driver's license. I went to a neuro opthamologist and he had no answers. I found an exercise online that improved my vision a great deal. I only get double vision now when I am very tired and when I first wake up. I also get ocular migraines. This stinks, but I have hope we will get help eventually. Ariza9110 you are not going blind.
