When you need to do quick repairs on your eyeglasses, CVS Health™ Eyeglass Repair Kit has you covered. Our kit is designed for use with all eyewear, including prescription, reading, safety glasses, and sunglasses. Inside the kit, you'll find a screwdriver, two metric and two American Standard hinge screws, a magnifier, a case, and a screw starter. Since most American-made frames require 5- or 7-barrel hinge screws and most imported frames use 1.4 mm or 1.6 mm metric hinge screws, we've included one of each in the screwdriver handle. When you're ready to repair your eyeglasses, first gently twist the magnifier onto the handle. Select the correctly sized screw. Next, insert the screwdriver tip into the screw starter and hinge screw into the other end. Make sure the leaves of the hinge are properly engaged. Insert screw and tighten. Do not force. If the screw does not tighten easily, then try a different screw. Forcing an incorrect size screw may damage hinge threads. If the enclosed hinge screws do not fit your glasses, see your local optician. They will provide you with extra screws which you can store in the screwdriver handle.
