@poorsaver, had the same supercontrasty vision when I had the coof 4 weeks ago. Blacks were really popping. Started about a week after symptoms started (had mild case, symptoms only lasted 2-3 days) and lasted a week. Went to the ER just to make sure nothing wrong, doctor never heard of issue. Didn't take IVM, just the over the counter FLCCC items, so maybe this is just a covid symptom. Only thing abnormal with my vision before covid is that I have red/green color blindness (protanomaly).
