Detailed Answer:
Thanks for using the Ask a Doctor service.
I have gone carefully through your query and understand your concerns. The changes that you describe are not normal and definitely require specialist intervention. It requires to be assessed by an ophthalmologist and also a neurologist. Just taking glasses is unlikely to resolve the problem. Some neurological problems could result in the symptoms that you have described. Please do that without any further delay.
Although the symptoms do not seem to be related to Covid 19, you may feel free to get tested at a center near you where these tests are done. A nasal swab would be taken and sent for the test.
