I have had a noticeable increase of seeing flashes of up to between 6 to 20 greenish spots in my central vision when I go from a light to dark room or vice versa..... when I close my eyes I see them clearly and they have grayish/yellow lines that stem from the spots into my central vision. They last from up to 10 secs to 2.50 minutes. I have been to an eye MD about this but he didn't see anything wrong. But at the time he didn't realize it was a light inducing phenomena, I thought it was from exerting myself. I see these every day now. But not constantly. I'm 48 year old female, with stigmatism, long sighted and healthy. My gp wanted to do an mri but she realizes now that I should go back to the eye MD and find out from him what it is... i'm just curios to know if anyone else has this?
