On Tuesday, the day after the big snowstorm in this New England state, I managed to make my appointment with Dr D, vision therapist-optometrist. I had thought that the problem, which was that I was having trouble reading due to the letters becoming jumbled and dancing around the page again, was my “constant or near constant exotropia” come back to haunt me. After three weeks spent largely in one small room in the hospital, a good part of that time using either glasses without prisms or at one point no glasses at all (because the lens had fallen out and I had no screwdriver to fix them with) I thought I’d “lost it” i.e. everything I’d spent so much time learning in VT.
Dr D did an exhaustive exam, or so it seemed to me sitting in the chair, my eyes getting wearier and wearier (!). However, when she was through, I was surprised to find out that the exotropia was actually quite a bit better, that in terms of my depth perception, I needed nothing more than to restart the exercises and perhaps spend some time looking at anaglyph pictures with red/blue glasses again — to reestablish the habit of seeing 3-D. According to Dr D I had all the ability to perceive it that I had had when I left her.
So what was the problem? Well, so far as she could determine, my right eye seemed to have become more myopic than before, enough so that I needed a new prescription. She seemed to feel that it was because of this that my vision felt jumbled, especially after reading a little while. Indeed, when she gave me the card to test my near vision, I could see every line quite well, as I usually could, since I have excellent near vision. But I knew that within minutes of reading a page of text, either in a book or more especially on the computer, I would begin to have difficulty (as I am even now as I write this). She felt that the increased medication was likely the culprit, and that if it was to be kept at this level, I should probably have my glasses changed to accommodate to it.
So all’s well that ends well. I left feeling a good deal cheerier than when I went in, knowing that I did not need to begin all over again, but only to do a tune up by myself, and get a new prescription if my meds are not going to be changed any time soon. (I may wait and see about that, since I do want to reduce the Abilify to a “humane” level, rather than keep it so high for good…I did well on 20mg for 18 months; I don’t see why I would need to stay on 35mg permanently just because of one relapse…Surely the increase need only be temporary…)
Tonight, I started “showing my brain” it could perceive the 3-D images that my eyes already see. I looked for my white, marked pencil for pencil push-ups, but couldn’t locate it, nor could I find the Brock string, though I had carefully stored both somewhere. (Lord help me, I am always doing that: packaging important items carefully with labels etc, putting them away for safekeeping, then promptly and completely forgetting where the hell I put them!) So instead, I put on my red-blue glasses and went to the internet site where I knew there were useful anaglyph pictures to get me started. If you happen to have red-blue or red-green glasses, perhaps from a three-D movie or graphic, you might like to check out this particular site, where the shots of Barcelona, and especially Gaudi’s work, are spectacular: http://www.3djournal.com/001/gal_Barcelona_3D.php
I was pleased to find that after some initial difficulty, I was soon able to resolve many of the photos into layers of depth, even a couple of pictures that before now I had not been able to see as three dimensional. What is more, upon taking off the glasses and looking around me, the world changed: suddenly, amazingly, the magic was back…Space was present again, holding things in its embrace, embodying even the flat surfaces of things, so that they now implied the substance that lay behind.
What do I mean by that statement, that space embodies flat surfaces so that they imply the substance that lies behind? Well, there is a book behind a flat book cover, no? Without the ability to see 3-D, one would not be able to know, without being told, that something was a book, and not merely a picture. The “bookness” of the book, the substance, the three dimensionality can be seen because of what space allows us to see, the continuity of a surface beyond the visible front. When I had not the same 3-D power of vision that I have now, I did not in fact see this continuity, so that unless I “knew” that a surface was a book, and therefore had the substance of a book behind it, I could only perceive the flat picture/cover presented me. It looked no different to me whether a picture, flat against the shelves, or a book, cover facing outward, and I would not know which it was, if I were not told. Of course, there can be monocular clues, clues like shadows and shading, clues like the oval on the top of, say, a glass or the curvature on the top of a book’s spine, versus the flat line of a picture. All give hints, but barring those freebies, space and depth perception are what tell most people that an object has substance, are what implies continuity beyond what is visible. Without the ability to know objects continue in space beyond what is strictly visible, you do not see the same object that the person with depth perception sees, much as you might believe you do. You can only know what you are supposed to see, say, the book, and then see it. But you do not first see the book, and then know it.
For a better example, take that palm plant I used to use as a touchstone for whether or not I could see properly. I knew it was a palm plant, yes, because it had long and multitudinous leaves, a mass of them. Now maybe I would have noticed this anyway, being an amateur botanist all my life, but what I did not do because I did not see them, was try to count the leaves, or find out where they were attached…Was there one stem or several, was it bush-like there, or similar to a tree? Looking never occurred to me, because it was just a jumble of green. I needed to be told what was there, in order to see or even notice it. Without that information, it escaped my vision; I failed to see, I failed to so much as think about it.
But that was before, now it is different. Now, and tonight in particular, the magic was back and sudden 3-D-ness made everything suddenly pop. Once again, I am filled with thanks for my original loss of depth perception, simply because in the regaining of it, I experienced, I believe, a sense of beauty that may be unique to those who, like me, have had to learn or relearn depth perception in later life. It is not something I regret in the slightest. If I missed it for some large part of 56 years, it doesn’t matter at all, because I have gained so much — well, I have no other word for it — magic now that it makes up for every minute when I didn’t have it or know what I lacked. After all, the past is gone, the present is all we have for certain, and the magic is here and now. I’m more grateful for it than I can say.
