Treasure your eyesight

I had an appointment with my eye doctor yesterday. A little over a year ago I was given a diagnosis of wet macular degeneration> I was legally blind in my right eye> I received an injection of Avastin in my eye. It greatly improved my vision. We considered it a miracle as my vision went from 20/200 to 20/40. Then about 9 months later, it was starting to come back so I had another injection. I had an appointment on Sept. 19 and my eyesight was still ok. But this past Tuesday my right eye was worse--20/60. I knew it was getting worse, because when I covered my good eye everything was blurry. So yesterday I had another injection.
I love to read and do scrapbooking, and I'm still working full time as a nurse, which requires good eyesight. So it's a little frightening to think that at some point these injections won't help anymore, or that it would spread to the left eye.
I feel very fortunate that these injections are available. And I feel blessed that I can still see to do all the things I need to do and enjoy doing. So for now, I am trusting that once again the injection will improve my eyesight. But I was thinking, before this happened, I'm sure I probably sort of took my eyesight for granted. I now have a great appreciation for being able to see. I truly treasure my eyesight.
