Men's Sunglasses for Square Faces

No. You can repeat angular lines or contrast them with curves according to your style. Check width, bridge and support before rejecting a shape; comfort does not depend on whether the frame's name matches your face shape.

Either can work as a styling choice. Rounded edges introduce contrast, while a straighter upper rim repeats angular lines. Compare frame thickness too: a fine or transparent rim is less visually prominent than a bold opaque front of the same shape.

No. Polarisation, photochromic technology and mirrored finishes describe different properties. Check the particular colour's product page rather than extending one model's features to the collection.

Not on its own. Check the stated category and usage instructions; a dark lens does not establish that it is polarised.

Rinse off dust and sand first and follow the manufacturer's instructions. Use clean microfibre; do not rub dry lenses with clothing.

No. Weight and fit are different. Check the bridge and temples while looking down and turning your head. A light frame that slides or presses at the sides may suit you less than a slightly heavier frame with better contact points.
