Start with fit and style: check the frame width, bridge size, and temple length to suit your face. Then review lens quality, UV protection, and whether a gold-tone metal square frame matches your wardrobe.

Key attributes are frame type and size (square gold frame, metal), lens type (polarized vs non), lens color or gradient, and comfort features like nose pads and spring hinges.

Consider when you'll wear them: daily use, driving, or outdoor activities. Think about polarization for glare reduction, coatings for scratch resistance, and whether you prefer Asian Fit or standard fit for comfort.

For a narrower face, look for smaller sizes or models labeled as Asian Fit. For driving or bright light, choose polarized lenses and a mid-tone tint to balance visibility and comfort.
