About 24 hours ago I had a sudden onset of flashes of white light in the outer corner of my left eye, also the sudden appearance of a single floater, which I typically do not have. The light flash occurs when a move my head sharply to the right or left. I am very afraid of anyone examining my eyes. I know that if this doesn't go away, I will have to have someone look at it to rule out a possible retina tear. My question is how long is a reasonable amount of time to wait before having my eye examined? I see online that many people have had this problem for weeks or even months at a time. On the other hand, I also see that if it is a retinal tear, it needs immediate attention. I really do not want to go if I can avoid it, so how long can I safely give this? It is not getting any worse and my vision is unaffected. Thank you for your help.
