I was seeing flashes of light and then I was seeing rainbow halos around lights I went to see an optometrist and he could find anything wrong . He said that my eyes ate healthy and there's.nothing wrong . I'm seeing flashes of light, he checked the front and back of my eye he checked my retina throughly and the proper back surface but didn't find anything, he said my eyes are healthy and its happening because I don't wear my glasses even tho I have to full time ?
