Hello, As you already met a GP what was his opinion towards the symptoms you provided. As we need to get some inputs from you. Any lab tests or MRI taken? Have you ever checked yourself with the Opthalmology department? Since you are not able to figure out why its happening and all, I would like to ask you - what sort of bad sight you have? Are you having double vision, blurred vision, any balance difficulty while walking, any other neuropathic symptoms? If any of the above is present you should meet up a neurologist and may be an MRI might be needed to understand the center of vision in the brain. The optic nerve also may need testing to understand if any optic nerve pathology is causing this or not. Also, have a check with the ophthalmologist so we can see if any visual disturbances are due to retina factor. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Jay Indravadan Patel, Physical Therapist or Physiotherapist
