I wear a special type of contact lens because it gives me much better vision than any glasses ever could. My doctor starts with "better or worse" and that gives her a starting point. Then we have measure and fit and then of course the weight and shape of the lens affects the shape of the eye, which changes the lens requirements so it takes several fittings and trials to usually get a good fit. Glasses are more like a hearing aid that just makes everything louder. Which will work in most cases. But many people need or want more.
