Hi Pete,
Sorry to hear of your emergency and can fully sympathize.
About 9 months ago I suddenly had impaired vision, looking through black streaks, and at the time was very near to a Specsaver shop. I went in, explained the problem and they immediately inspected.
Luckily they didn't send me on to the eye hospital, I had detached soft membrane from the back of the eye. They fully described the problem and issued me with printed details and instructions for the future.
The charge for this service ....nothing and I am more than grateful to them.
I later followed up with a visit to an eye specialist, just to be sure and he confirmed the diagnosis.
At the time it was very scary and I am grateful for the help I received. Incidentally, I am not connected to Specsavers and don't have my specs from them.
I wish you well
