Yesterday when I woke up from sleep I had a very strange vision for twenty minutes. All moving objects in my vision were a leaving trail. Like double vision. Like a video effect. But only the moving objects. I am really scared. It resolved after 20 minutes but I still see sometimes flashes of shadows. Such thing has never happened in my life. I am 28 years old. I had laser peripheral iridotomy one year ago. I am not sure it's the eyes or the brain that was doing that. I don't have glaucoma. I get migraines pain in my eyes sometimes but was not having one yesterday. I have 6/6 vision and don't require glasses. Please help. Can't go out because of lockdown.
