The clarity of polycarbonate sheets can indeed be comparable to that of glass, especially when high-quality sheets are used. Advances in manufacturing techniques have allowed polycarbonate to match and sometimes exceed the optical performance of glass while offering additional benefits like enhanced safety, lower weight, and potentially lower costs. The choice between polycarbonate and glass ultimately depends on the specific requirements of the application, taking into account factors beyond clarity alone. Whether it's the need for superior impact resistance, lightweight solutions, or cost-effective alternatives, polycarbonate sheets have proven themselves as a viable and competitive option in the world of transparent materials.
