I found a text on my phone about 2 to 2 and a half hours ago on my phone saying that I had a message on my journal from UC,so I logged into my account and found a message saying that they need to know more about my health condition or disability, but they didn't say which one they need to know more about.
They said that they'll be sending me the How your health condition or disability affects you form (UC50 I think it is called) in the post.
The only one I can think of wanting to know more about is my recent health condition which is the start of a catteract in my left eye, which doesn't affect my eye sight at the moment but it will in the future.
The diabetic optician who diagnosed me with the start of a catteract in my left eye said that he's not worried about it for the time being, so he's leaving my diabetic eye checks to yearly for now.
I also have yearly NHS eye appointments for my eyes at my local opticians too.
