Square Eyeglasses and Sunglasses

Square frames bring clean angles and balanced structure to the face, making them our most popular everyday shape for softening round or oval features. This collection brings together our full range of square prescription eyeglasses—our core focus—alongside our selection of square sunglasses and magnetic clip-on frames.

Every eyeglass frame on this page can be ordered with custom prescription lenses (single vision, progressive, reading, blue light blocking, or photochromic) or purchased as a frame on its own. You will find three main constructions across the collection: bold full-rim frames in rich plant-based acetate and flexible TR-90, refined semi-rim browline designs that keep the lower lens edge open, and featherweight rimless square frames crafted from pure titanium and beta-titanium for all-day comfort.

Getting the right fit online comes down to three millimeter measurements listed on every product page and size chart: lens width, bridge width, and temple length. Comparing those three numbers against a pair you already wear comfortably is the most reliable way to choose your size across men's, women's, and unisex fits.

For outdoor wear, our square sunglasses and clip-on models pair the same durable titanium, TR-90, and acetate builds with polarized lenses that cut surface glare and UV400 protection that blocks 100 percent of UVA and UVB rays.

USA shipping and taxes are included in every price.
