Algorithm Rectangle Eyeglasses are rimless titanium prescription frames with a clean rectangular lens shape, matching the product images and suited to wearers who prefer minimal frame lines. As an optical choice, this style keeps the face open while still offering adjustable nose pads for fine fit control. Can Algorithm Rectangle be made for daily prescription use? Yes, it can be fitted with single vision, invisible progressive, bifocal, blue light blocking, photochromic, prescription sunglass, and higher-index lens options when your prescription and fitting measurements are suitable.

If you already have a pair of glasses, you can compare the measurements to your current frame. Just look inside your temple to find your frame measurements.
