Start with fit and lens type. Check frame size and shape for your face, whether you’ll wear them as glasses or sunglasses, and confirm UV protection and prescription compatibility if you need corrective lenses.

Compare lens options (clear, tinted, polarized), frame material and size, and whether the model supports prescription lenses. Also note the bridge width and temple length for comfortable wear.

Consider your use-case (daily wear, driving, outdoor activities) and style preferences. Special editions or labels (like Zac Efron or Men in Black) can guide aesthetics while still meeting practical needs.

Look for UV protection and, ideally, polarized lenses. A mid-size frame in a neutral color tends to be versatile, and ensure the model can accommodate prescription lenses if needed and fits your face shape.
