Aviator vs. Rectangular Sunglasses: How to Choose a Shape
Two pairs of nearly identical width can frame your eyes quite differently. Lens height and the line across your brow are the easiest differences to spot.

Compare the depth on your cheeks
ALIENY SUN I is 55 mm tall at the front. FREQUENCY SUN measures 43 mm. That 12 mm difference changes how much of the cheek the frame covers. Hold a ruler beside your current pair to picture the difference.

Trace the top line
A double-bridge aviator leads the eye inward toward the bridge. A shallow rectangle carries the line of the eyes outward toward the temples. Take two photos at the same distance and look at where each upper rim meets your brows.
Try them with your hat or headphones
Bring the accessories you wear on a normal walk. Look down, smile and turn your head. Check whether a brim pushes the frame down or a headphone cushion presses a temple into your ear. If both pairs sit comfortably, compare their profiles in a side view before choosing.
