Ok Dear customer I would recommend  if you haven’t seen any improvement during all these years , a good option would be Neuromodulation refers to devices that stimulate the brain and nervous system using magnetic waves or electric currents. They may be an option for people who prefer to avoid medication, cannot take medication, or have symptoms that do not respond to medication.

Migraines can be triggered by many different things, including stress, physical exertion, fatigue, lack of sleep, hunger, odors, chemicals, and certain medications and substances . In females, migraines can be triggered by the normal decrease in estrogen levels that occurs before the menstrual period each month.

Migraine is the most common cause of Transient visual loss in young adults , especially if there is a history of headaches with migrainous features.

However I would highly recommend you that you should get evaluated 

You should see a neurologist as the next step of further evaluation

Dear customer I’m very sorry that you are passing through this situation.

Binocular dysfunction often results from dysfunction of one or more of the extraocular muscles.

Three pairs of extraocular muscles move each eye in three directions: vertically (superior and inferior), horizontally (medial and lateral), and torsionally (intorsion when the eye rotates toward the patient's nose and extorsion when the eye rotates toward the patient's shoulder).

The examination should focus on establishing which particular extraocular muscle or muscles may be weak. The presence of pupillary or other cranial nerve abnormality and other ocular findings are also important.

When the pattern of muscle weakness suggests that the problem is isolated to a single cranial nerve, the differential diagnosis is specific to the individual.

The extraocular eye muscles are often involved in myasthenia gravis.  Multiple extraocular muscles in both eyes are typically involved and ptosis is also often present. Fatigability and variability of clinical findings are characteristic clues to this diagnosis.

●Thyroid ophthalmopathy leads to muscle tightness and restriction of movement. Proptosis is usually also present.

●Other causes of binocular dysfunction affecting multiple, bilateral extraocular muscles include orbital myositis, Tolosa-Hunt syndrome (THS), Miller Fisher variant of acute inflammatory demyelinating polyneuropathy, and structural and/or inflammatory lesions involving the skull base cavernous sinus, or basilar meninges.

The treatment basically depends on each individual situation.
