Usually it takes me an hour for my eyes to recover to a point where I can drive. My vision is no longer cloudy before that but everything is just too bright.
I do get an terp for my eye exams. Although I have gone without one, It helps a lot. Once I take off my glasses I can still understand the terp but I cannot clearly see the doctor's face for lip reading. Also, they ask a lot of questions while you are looking at something or in the dim light that I miss.
For my primary doctor, I have been struggling with getting a terp there. They use VRI and too often they can't get it working. I have had appointments rescheduled or just have to go with writing notes. Sadly, even calling ahead of time asking them to test their equipment before my appointment, they again couldn't get it working last week. I do like that my doctor is very willing to write and after my last appointment he started learning some signs. It was nice that my communication with the doctor was a bit better between the writing and some signing. The conversation is a bit less detailed than it should be because of the communication method though.
He did make a request for a live interpreter for our next appointment since they have been having trouble but I'll have to see if they follow through. The doctor seems to get it and cares a lot but the staff who are responsible for setting up the equipment and scheduling don't seem to understand the problem.
