I had my barrage laser in 2008 because I had multiple lattices in both my eyes... every year i go for eye checkup once... i had been seeing a flash or stars like thing on my left eye. It seems like some stars being on the periphery top of my eye and then slowly travel downwards and dissapear. I got scared and went for test today.. but retina was perfectly fine and doctor asked me to continue the glasses. What can it be?? Also I use a lot of phone and laptop and my screen time is more due to which sometimes I get headache.
