Well, without a detailed clinical evaluation it would be difficult to determine the cause of your symptoms or suggest management plan. Possible causes of the symptoms that may need to be considered include glaucoma, cataract, TIA, amaurosis, ocular migraine etc. I would suggest getting this evaluated by an ophthalmologist initially for a detailed evaluation and if required a neurological consult may be sought if ophthalmic causes are ruled out. After a specific cause is identified, a management plan can be initiated accordingly.
Hope this is helpful.
