Decide between sunglasses and optical frames, check fit options (including Asian Fit), assess the frame size and bridge width, and verify lens features (UV protection, polarization for sunglasses) and whether prescription lenses are supported.

Primary attributes are fit and size (including Asian Fit variants), frame finish (gold-tone), lens type (sunglasses vs glasses, polarized or non-polarized), and whether the model supports prescription lenses.

Consider intended use (daily wear, driving, outdoor activities), comfort (weight and nose pads), durability and materials, and style preferences like shape and branding.

For bright sun and glare, choose models with UV protection and polarization; for prescription needs, look for frames that accommodate lenses and check sizing; if you prefer a narrower fit, look for Asian Fit options.
