The importance of your sense of vision, your #eyesight, has been rammed home to me over the past fortnight. I had a corneal graft a couple of decades ago in one eye, which worked but I still need contact lenses. A couple of weeks ago the blood vessels on the front of my eye managed to find the graft and immediately tried to kill it as a foreign body. My eye was soon a mess and I was losing vision in that eye fast, as far as failing the how many fingers am I hold up test. Well it was correctly diagnosed and treated quickly, with strong steroids to inhibit the rejections, and I am well on the road to being to see with two eyes. What a blessing sight is!
