Start with UV protection (UV400), then consider glare reduction, frame size, and weight. A comfortable fit and durable materials help ensure the pair can be worn all day.

Key factors are lens technology (polarized vs non-polarized), lens tint and visibility, UV protection, frame style (Aviator, Wayfarer, rectangular), and the size/fit of the frame.

For driving, prioritize polarization and glare reduction; for outdoor activities, choose durable frames and a larger lens for coverage; for everyday wear, favor timeless shapes and comfortable fit.

Think about your style vibe and face proportions: classic aviator or wayfarer styles for a timeless look, oversized or chunky frames for a bold statement, and pick a size that feels balanced on your face.
