Rectangle

Rectangle frames are noticeably wider than they are tall — typical proportions are around 2:1 or 1.8:1 lens width to height. Square frames are closer to 1:1 (equal sides). Rectangle reads more refined and traditional; square reads more contemporary and bold. Both work for round and oval faces; rectangle is slightly more flattering on shorter face heights because the elongated shape adds visual length.

Yes — rectangle frames have one of the largest lens-area-to-face-coverage ratios, which is helpful when you wear sunglasses outdoors and need to see screens (phone, watch, car display) without removing them. The wide horizontal cut also matches typical screen aspect ratios, so eye movement stays natural. For dedicated screen use indoors, consider the Blue Light Glasses collection in this collection instead.

Quince sunglasses use Italian acetate frames — a plant-based plastic derived from cotton and wood pulp that holds rich color, polishes smooth, and feels warmer and lighter on the face than petroleum-based plastic. Acetate is hand-polished, hypoallergenic, and durable enough for daily wear. Hinges are stainless steel with five-barrel construction for smooth opening over years of use.

Polarized lenses are available on most Quince sunglasses styles — check each product page for the polarized variant. Polarization filters out horizontal-axis glare from water, snow, roads, and car hoods, which sharpens contrast and reduces eye fatigue. For driving, water sports, and bright-sun environments, polarized is the better choice. Non-polarized lenses are slightly less expensive and work fine for general use. All Quince lenses block 100% UVA and UVB.

Yes — all Quince sunglasses block 100% of UVA and UVB rays, the standard set by the American Optometric Association for sun protection. This holds true regardless of lens darkness; tint controls visible-light reduction (how dark the world looks), but UV blocking is a separate coating on the lens. Daily UV protection helps prevent cataracts, macular degeneration, and pterygium — the same UV protection you give your skin.

Sunglass fit is mostly about frame width — the distance across the front of the frames should match your face width (measured temple to temple). Each Quince product page lists frame width (typically 130-150mm), lens width, bridge width, and arm length. As a general rule: 130-138mm fits narrow faces, 138-145mm fits average faces, 145mm+ fits wider faces. The arms should curve gently over the ears without pinching.
