Product Information

On the temple half joint, the hinge body conceals a spring which allows the temple to extend beyond it's maximum range of motion. This makes the glasses frame more adaptable for more head sizes as it can "spring" wider than a traditional tenon hinge. In the images above, you can see the characteristic cross head at the top of each of the screw-heads.

There are numerous styles of temple, but their main function is to keep your glasses secure when you’re wearing them. Cross head screws are slightly less common and use a cross shaped (Phillips) slot in the top of the screw head. Using a machine, the temples are bent to give them a drop end. The wire core maintains this hook and prevents it from becoming deformed over time. There’s the optometrists who have their own secret code... then there’s makers like us who have our own entire glasses language too. To locate the lens fully into the lens groove, the frame front is gently heated using an optical blow-heater. This makes the frame front more malleable which allows a skilled technician to slightly stretch the frame over the full edge of the lens.Instead of using pad arms, full rim glasses frame made from acetate or horn commonly use what's called a pad bridge.

Deco rivets are used on full rim frames to mimic the appearance of actual rivets. Instead of passing through the frame, deco rivets are entirely superficial, added to the surface of a frame which uses hidden hinges. Some frame materials can be adjusted at home, while others require professional attention. This is the case for glasses made from: Half rim frames also have a lens groove but with the addition of a Supra chord. This nylon string locates into a female recess around the edge of lens which holds it into place in the frame. Together, this makes the optimum angle and depth to receive the bevelled edge of an optical lens. As the lens groove is female, and the edge of the lens is male, this union creates a reliable, repeatable connection without the requirement of screws or adhesives.Seen in the image above, each of the charniers have a hole in their centre's. This is where a threaded screw locates to secure all the loops together. Each half of the fully assembled hinge is called a half joint. Wireframes bend easily. You can bend them with your fingers or use a small pair of pliers to gently adjust the arms. If the problem is that the frame size is wrong, you’ll need to invest in new glasses. There’s only so much you can do to make glasses fit your face better. Summary
