Visual Disturbance. Reduce this problem?

I think your headache & disturbances in vision is not related with migraine but dryness (computer Vision syndrome). Number of blinking drastically goes down from around 24 per minute to around 8 per minute leading to severe dryness ,blurring of vision& headache while working on computer for long time without break.One should try to have normal blinking while working on computer or smartphone & one should look away from screen every 15 minute & one should take rest for 10 minutes after every two hours who are addicted to smartphone or computer. You must use lubricating eye drops 4-5 times(Refresh liquigel) regularly to avoid yourself from dryness. If you don't get relief within a week ,you should consult ophthmologist for refraction & neurologist for migraine, with regards
