Thank you for your query.
I think you need evaluation for your eyesight .I think you should see an ophthalmologist for this purpose as you have already taken an appointment for this problem and get yourself evaluated.
There can be multiple causes for headache and eye problems but one thing you could be having is migraine
in which people get an aura of visual nature.
Hope you are satisfied with the answer.
If you have any further queries feel free to ask.
Wish you good health.
