Hi, please help. Dh has been getting halos in his vision at night. It did happen a couple of times a few years ago, then nothing until now, when it's been most nights. Is it just stress? He's incredibly stressed, working constantly and very little sleep. Gp looked in eye and suggested blood test. Our town has an urgent eye care hospital which triages via the phone. Should he call them first thing? He has no pain, but does need to drive at night. He's really panicking as it's come on over the weekend when he doesn't feel he's stressed with work, but I explained that stress doesn't just switch on and off. Please help!
