clear to me now.
First, blind spots are not darkness or emptiness in the visual field. Those ideas are in and of themselves visual. Try looking at the floor with your feet. Thatâs what blindness looks like. We canât see it, or see it even as an absence in our experience. An omitted image doesnât alert itself to your attention until, say, you shoot past a stop sign, and, wow, suddenly it appears in the corner of your eye. Only then does it
occur to you that something was out there, something that did not appear when it should have. Hard to test for that.
Another explanation is particular to my retinas and their degenerative pattern. Nobody tested me for night vision. An inability to see in the dark is one of the early effects of my disease. When it came to reading the eye chart and identifying the road signs, my eyes did their duty. But put those same signs under a street lamp on a foggy September eveningânow thatâs another phenomenon, and one I would have missed.
I do remember the administrator checking my peripheral vision. He flashed a couple of bright lights to be caught only by the corner of my eye. Fine. Then he checked my central vision with the usual alphabet soup made into an eye chart. I passed that, too. But the real problem was everything else. Imagine your visual field, the dimension of all that you see, shaped like a dart board. I could spot the bullâs-eye and the outer ring, but the middle or inner rings, they remained a Swiss cheese of tiny blurs my brain refused to see. My cognition, like anybodyâs, compensated for the small, missing pockets in between. I saw, in other words, by inferring what wasnât there, what connected the edges to the center of my sight. The holes werenât large, but they were growing, and a lot could disappear within so little. Roll a newspaper and hold it like a telescope to your eye. Huge, distant objects can fit inside. Far enough away, even a truck could drive through. Sometimes they did.
Finally, nobody tested for the depth perception I didnât have. Had the administrator of my exam seen me on the job, now waiting tables in a local café, he may have thought twice
about taking my picture and giving me a licence to cruise. At work, my hands regularly jammed through stands of water glasses when I meant to grab the first one. Dropping plates on a table with excessive force, as if in disgust at a customerâs preference for blue cheese dressing over a nice balsamic, was a habit, too. Like my days at the pool factory, these manners were dismissed as traits of my character. Ryan, the clumsy guy who slams things. So moody, so distracted.
Sure, I sensed difficulty when I drove, but it came and went depending on the weather or time of day. Driving home at night from the café, the roads dark and wet with rain, I could vaguely detect the double yellow line. I thought, as my parents had said, the problem was my lack of experience. They also agreed it could be difficult to spot a painted line on a puddled street. What did I know? I wasnât going to dispute my parentsâ opinion or insist my difficulties were a tad worse than they imagined. Argue myself out of driving? I was seventeen, not some kind of safety nut. To help find the rainy night lines, I often relied on the raised catâs eyes, the solid reflectors that peppered most of the routes home. Not that I looked at them. If no other cars could help me position myself in my lane, Iâd ride the catâs eyes and feel for the âclunk clunk clunkâ under my tires. At night I drove Braille. Didnât everybody?
I kept the first accident to myself. The very afternoon I pocketed my driverâs licence, I drove straight to my girlfriendâs house to take her out for a spin and anything else a car might encourage. She wasnât home. As I left the winding streets of her neighbourhood, I fumbled with all the serious business of driving. I lit a smoke, or
