As someone who’s tried both, the difference between glasses and contact lenses is distinctive in many ways. One of the core differences is that contact lenses – unlike glasses – also enhance your peripheral vision. I’ve found this at times to be a distinct advantage. There are things that you see out of the corner of your eye, and being able to see them clearly is useful.
Neither glasses nor contact lenses, however, fix the old problem of being unable to see what’s right behind you. Now, in most circumstances, that’s just part of being human and not a problem. But when driving (and especially when reversing) there are all sorts of reasons why it’s important. That’s why we’ve put considerable effort into finding workarounds – rear view mirrors, wing mirrors, and so on. Our best solution so far is probably the rear vision camera.
Rather than using reflections, the camera directly shows you a feed of what’s going on behind your vehicle. It doesn’t distort distances the way mirrors do – in fact, it shows a scale on a screen to help you gauge distance – and it works at night, providing a major advantage over other methods. Not only that, it also can be attached to trailers (including caravans). A reversing camera is quickly becoming essential for drivers who really care about safety.
Larger vehicles, like trucks and motor homes, are especially wanting of these cameras. RV rear vision cameras are available, and having a camera for these sorts of vehicles is important because some of them are just too big for rear vision mirrors (and wing mirrors are awfully unreliable). You know all those “If you can’t see my mirrors, I can’t see you?” signs on trucks? Well, those should rightly be a thing of the past thanks to rear vision cameras, bringing us into a safer future.
