I went for an eye test this morning as I have been having daily migraines and trouble focusing. The tests took 1 1/2 hours and I had to have some done again and for longer. One result is that my pupils are not dilating as they should be. The optician is writing to my GP to ask if it could be a result of my medication but also said I need to see the GP about the migraines. I am currently having my 3rd migraine of the day but the optician said there is nothing wrong with my eyes that would be causing them. I also felt very sick after having the light flashes in my eyes and some tests done.
