I am very short-sighted and for the past 20y have been warned at every eye test that if I see flashes I must contact my optician immediately. It can be a sign of retinal or vitreous detachment, and can lead to permanent loss of vision if it's not treated urgently.
Last night I started seeing flashes streaking downward in the outside edge of my left eye, and they are still there now. I have emailed Specsavers, but I am very worried - this may be exactly the sort of thing that will be deprioritised by Covid.
Any words of advice?
