About this deal

Tapered rivets have a conical shank and don’t have a top. Instead they taper from a wide head down to a narrow tip at the bottom.

Once filed, the acetate or horn can then be hand polished to make each pad smooth again so it won't rub on your nose. Characteristically, tenon hinges do not have any “give” as they are not sprung. When the temple is fully open and meets the frame, a tenon hinge will no let it open any further; a similar function to a house-door. Instead, hidden hinges are inserted into the frame via heat or ultrasonic friction which rapidly melts the acetate surrounding the hinge. Another name for your glasses hinges, a fully assembled joint comprises of two half joints held together with a dowel screw.Pan head rivets look similar to a wood-nail. They have a uniform 1mm shank and a wider, circular flat top which can be seen on the frame front endpiece.

Instead of using screws and tenons, mechanical hinges may use entirely wooden or intricate folded metal parts which avoid the need for pin riveted hinges. As mentioned previously, the rivets are located through small diameter holes in the frame front and the temple which are used to permanently fasten the hinges. Once located, a nose pad could be attached via a very small threaded screw through the box-section of the pad arm. The box allows the nose pad to pivot slightly to accommodate the shape of your nose. If your glasses cause discomfort or redness or slip down your nose, see a professional eye care professional. In most cases, a skilled eye care professional can make the proper adjustments to your frame and temples so your glasses fit comfortably and stay in place. For sunglasses, side shields tend to made from entirely opaque materials such as suede leather or rubber. This is to reduce sunlight from "leaking-in" from above, below or from the sides of the lenses.

Your hinges are the metal joints which allow you to open and close the temples on your glasses frame. In each of your hinges, the dowel screw locates and into each of the threaded tenons. Using a flat-headed screwdriver, the screw is wound tight to pull each half joint together to create a firm and durable connection. There are many types of spectacle lenses, which were originally made from glass. However nowadays, most if not all spectacle lenses are made from types of high index plastic. If you've made it this far, you'll know by now that there's A LOT of styles and types when it comes to the various parts of glasses.

This style of bridge resembles that of a traditional key-hole. As you can see in the image above, the keyhole bridge emits a classic,1950's aesthetic. This bridge-style is ubiquitous with mid-century eyewear design and production. Double rivets have two 1mm shanks which are joined together at the top via a conjoining strip of metal called a cross bar. Rivets like these can be branded or styled as per a company’s branding.Glasses temples are made at various lengths to suit different head sizes and vary from 120mm to 150mm in length.
