Pat, hello and welcome to the forum. I am sorry to read where you are, and while this isn't good at any year Christmas is a whole lot worse.
As for driving, i have only had one eye to be able to see, as the other has never seen anything, but i passed my test six years ago and still drive with only one eye. As others have said here, you just need to have 6/12 vision in ONE eye to be legal, but you do also need peripheral vision, being that you can see all angles so as not to cause an accident. This is why those with glaucoma have a problem, as that affects central vision.
You can get this checked with a test at a local optician. DVLA if contacted will provide you with details of the nearest one to you and pay for you to take the test. You have to look into a screen and follow a light around it, while pressing a button if you see a red light out of the corner of your eye. It isn't a bad test, but maybe to those used to seeing with two eyes it would be difficult. I guess i found it easy as i have had over twenty years experiecnce with only one eye so was used to it!
So i guess it would be best to check with your optometrist about your vision at present, and while they most probably won't contact DVLA, that you are required to yourself if you get any vision changes. They will then contact you with details of a visual test. This though doesn't help when you need to drive now and you have to wait!
Please take care whatever you decide to do, and know that most people on the road are probably only driving with one eye anyway!

Hehe, do we dare get back on the road again!!!
