Velo Vision

Focus
About a year ago, I started to notice that I couldn't see things in the distance as well as I used to. I could read and see up close just the same as before, but things far away were losing their clarity. I noticed this most of all while cycling.The landscape was not as sharp as it once was, far-away roadsigns were more difficult to read, faces of people riding toward me were harder to recognise. As someone who's always had perfect eyesight, I had no prior experience with vision loss and it took me a while to acknowledge what was happening. But finally I went to have an eye exam and the loss of "perfect" status in the eyesight department was confirmed. I was given a prescription for glasses that the doctor said I would need mostly "for driving."




Glasses

I expected shopping for glasses to be a nightmare, for the same reason finding a decent pair of cycling sunglasses had been a nightmare. But I underestimated modern technology and our neightbourhood's offering of optical shops.Picking up friends' glasses in the past, I remember them being heavy. But apparently eyeglasses today can be made extremely lightweight - with high-tech plastic and titanium frames. There is also enormous variety in shapes and sizes. I had no problem finding some that fit my face and weighed next to nothing.




Glasses

With cycling in mind, I got a pair with plastic frames and photochromic lenses. They cover a good part of my face, and the lenses turn dark in the sun, but clear at night. I have already worn them on a couple of rides and the fit is very comfortable.But wearing corrective lenses will take some getting used to!Everything in the distance now looks unnaturally sharp, or hyper-3-D. My feel for how close or far away objects are is a little disturbed by this, but I am assuming my brain will adjust eventually.




Focus

Another thing that's happening, is that whilethe glasses correct my far-away vision, they do so at the expense of making things blurry up close. On the bike, this means that I can't really see anything that's directly in front of me or at handlebar level (i.e. the cycling computer on my roadbike) unless I take them off or look underneath the lenses. I am still working out how to adapt to this. Meanwhile, it's a relief to see clearly at a distance again.
