Gradually, some of the 'finer grained' images faded from view, until, until just a few months ago my right eye also started to fade, and that at an alarming rate. Crossing the road was beginning to be a hazardous undertaking. Reading was becoming very difficult and tiring to boot. So bad was it withal that in August I set wheels in motion to get the problem fixed. Unwilling to take my chances on a lengthy wait through the public health system, I 'went private'. Fortunately, I had enough money by that I could pay for it without borrowing.
Now, in mid-December, cataracts have been removed from both eyes; my 'unaided' vision is better than it has been since I was 13 years old; and I am enjoying reading again. "I can see again! It's miracle!" ... I did so want to be able to say that. Now I can see all the 3D images in this book, including that on the front cover and the end papers. Wonderful.
(I found I could resolve these two images 'on screen' as well. Even up to the end I could still resolve the two with only a little difficulty. So you might want to give them a go. No spoiler alerts...)
