Polycarbonate lenses have a high index, and are light and far more impact resistant than ordinary eyeglass lenses, so of course, it is recommended. By the way, it also blocks 100% of UV rays!
Although polycarbonate lenses have many advantages, they are not very expensive. They are generally available for around $50, although polycarbonate lenses with other features (photochromic or polarized) can be more expensive. You can even get them for about $20 at ABBE Glasses.
