I sometimes experience eye disturbance which makes me to see strangely like in the picture I have shown. I learn it is called ocular migraine . My own comes suddenly and lasts for about 20 minutes but is very discomforting. My eyes return to normal after . In my case it I triggered by stress and most often while looking at computer or mobile phone. It comes averagely once in 2 months, sometimes twice a month. Is there anyone who has experienced this and have you been able to find a permanent cure?
