Clip On Glasses

Early clip on frames were designed for two purposes. They were often used to hold reading glasses. The primary frame held distance lenses. When the user needed a reading lens, he or she simply installed the clip on glasses. The clip-on frame was also used to hold clip on sunglass lenses. Most vintage clip on’s were desiged for use with round frames suach as Windsor and Marshwood frames. Early clip on were also made in the ovid style. The ovid style is often referred to as “P3”. Generally clip-on sunglasses frames are slightly larger than the frame they are attached to.
