halfrim

Halfrim is a style of eyewear frame in which the rim encircles only a portion of the lens. In halfrim designs, the frame supports the lens along one edge—typically the upper or lower half—while the remaining edge remains rimless or minimally outlined. This creates a lighter silhouette and exposes more of the lens edge. Halfrim contrasts with full-rim frames, which surround the entire lens, and with rimless designs, which attach lenses with hardware at the temples.

Construction and materials: Halfrim frames are commonly built with a thin metal wire or a slim acetate band forming the rim along the designated edge. Lenses are secured by grooves, screws, or clip-in mechanisms, and hinges connect to temples that may be metal or plastic. The reduced frame material can offer lighter weight and a more unobtrusive profile, though it can influence durability and mounting options.

Variants and aesthetics: Top-halfrim frames trace the upper edge of the lens; bottom-halfrim frames trace the lower edge. Shapes include rectangular, round, or cat-eye, and material choices—stainless steel, titanium, or high-quality acetate—affect feel and color. Some designs emphasize a sharp line along the rim, while others use a softer curve.

Usage and reception: Halfrim frames are widely used in fashion eyewear and in prescription glasses and sunglasses. They are valued for a contemporary, lightweight appearance and a balance between visibility of the lens and structural support. Care involves regular cleaning and careful handling at the mounting points to prevent loosening.
