Q1: What sunglass styles look best on my specific face shape?

Comparison of different lens materials for sunglasses: polycarbonate, glass, and CR-39.
Q3: What are the main differences between lens materials like polycarbonate, glass, and CR-39? Which is best for durability, clarity, weight, and scratch/polarization options?

Polycarbonate (most common) - lightweight, impact-resistant, good UV protection (ideal for sports/active use). Glass: Superior optical clarity & scratch resistance, but heavier and breakable.
