EyeWearStraps NEW One Pair Black Replacement Glasses Temple Covers Tips Ends For Metal Arms

Product Information

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. 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. Temple tips is the industry name for the arms of the glasses which go across the wearer's temple. They're not actually just tips, and they can have a big impact on how comfortable a pair of glasses is to wear. OptiSource offers a wide variety of different temple tips in various colors and shapes, allowing a pair of glasses to be customized and made more comfortable as needed.

From above, you’ll notice that the bridge protrudes slightly from your glasses frame. This is called the “bump” which creates room for the crest (top) of your nose as the glasses rest on your face.

Properly fitted glasses with the correct temple length should hold your glasses securely in place without discomfort to your head, ears or nose. This addition is made from acetate and acts like a tubular sheathe which envelopes the outer edge of the wire. The tubular, hollow acetate is very fine and has a split down its length to accommodate the frame.

In the middle, a metal bridge is screwed onto the innermost edge of each lens. The screws pass right through the lens which make the basic frame front. At the outside edges (the endpieces) the hinges are also screwed through the lenses to complete the frame assembly. Another name for your glasses hinges, a fully assembled joint comprises of two half joints held together with a dowel screw.Push in nose pads vary in shape, size and material depending on your preference. The bigger the nose pad, the more visible it is. However large nose pads distribute more pressure and are less likely to “dig” into your skin. Depending on the type of frame front, your lenses are secured into your gasses using different types of friction fit. The optical term for fitting your lenses is a process called glazing. Full rim nose pads are almost always part of the frame front. When the frame front is being cut from the acetate or horn sheet, the nose pads are sculpted as part of the frame as a single piece. This melt makes a sturdy bond between the hinge and the frame without the need for rivets. As you can imagine, hidden hinges are a sleeker design with less components, however they are very rarely repairable. If your glasses have tenon hinges, they’ll most likely be fastened via two or three little metal rivets.

This is where two little humps are sculpted into the frame front which rest on either side of your nose. Pads like these are extremely common in modern eyewear as they are made during the CNC machining stage of production. Acetate comes in a vast variety of colours, patterns and transparencies which make it one of the best polymers for spectacle making. But the shortcoming of silicone temple tips is it attracts dist easily. So usually advise you to change it every 6 months or 3 months. Acetate temple tips : Glasses frames comprise of three main parts, containing multiple sub-parts within their construction. Primarily, there is the frame-front and two protrusions known as temples. These main components come in many different forms and materials which have their own specific functions, styles and names. Style rivets have a decorative head which can be shaped to resemble a company emblem or certain geometry. These are less common but offer minor degree of differentiation from regular pan head or tapered rivets.

For facial comfort, the bridge of your glasses has two main functions. These come from bridge bump and the bridge aperture. Before plastic came on the scene, (1907,) natural materials such as bone, wood, ivory, horn and real tortoise shell were used to make the frame front and temples of a glasses frame. Since then, materials such as cellulose acetate has generally made these older materials obsolete. Rimless endpieces are actually part of temple instead of the front. Beyond the hinge is another section of metal called a “lug”, which is usually a bent at an angle of about 96°. The lug is then screwed through the lens to create a firm joint. 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. Regular bridges are a continuous, flowing shape which make a U-shaped slot in the frame front. This style of bridge is relatively modern and is very simple in appearance.
