    Abstract: The present invention is a pocket clip kit for eyeglasses. One embodiment includes a one-piece pinch pocket clip made from a single piece of resilient spring material and including a pinch feature that allows conventional eyeglasses to be easily clipped onto a pocket. The invention also includes a method of attachment of a suitable spring clip to the eyeglasses using heat shrink tubing. The pinch or spring feature allows the user to open the clip while inserting the eyeglasses into a pocket. When the pinch tab is released, the clip securely grips the pocket fabric against the heat shrink tubing. The objective is to provide a device which easily attaches to a pair of eyeglasses allowing the eyeglasses to clip onto a pocket, and thus preventing the eyeglasses from inadvertently falling out of the pocket and being damaged.
