Algorithm Square Eyeglasses are full-rim TR90 prescription frames with a softly squared front, matching the product images and color options. From an optical fitting standpoint, this style works well for wearers who want a lightweight plastic frame with a stable molded bridge and enough lens depth for everyday correction. Can these square glasses support multifocal lenses? Yes, the frame is marked for progressive and bifocal support and can also be ordered with single vision, blue light, photochromic, prescription sunglass, and higher-index lens options when suitable.
