Product Information

If your glasses squeeze your temples, you should loosen them. It’s common to experience headaches and discomfort when your glasses squeeze too tight.

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. Fig.9 is a side perspective view of an example of the use of glasses according to the invention placed on the nose of a user, in front of glasses required for him, whose plates rest on the plates of these glasses, protecting them. 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. Seems logical…but the proper name for them is temples, simply because they locate on each side of your head.This article will discuss different ways to adjust your glasses at home. How to Adjust Your Glasses at Home Over time, dowel screws may work loose, so it's always handy to have an optical screwdriver to keep them tight, but not too tight. An example of a five charnier glasses hinge with a two rivet cluster. The frame half-joint has two charniers and the temple half joint has three charniers. Throughout Arthur Koestler's Darkness at Noon reference is made to the fact that the main character, Rubashov, wears pince-nez and uses them to tap on the pipes in his cell to communicate with fellow prisoners. In Darkness at Noon the pince-nez signifies Rubashov's belonging to the intelligentsia where a fellow prisoners monocle represents their belonging to the aristocracy.

For spectacles, side shields are generally used as a protective measure, especially in factory environments. To aid vision, they're usually made from transparent, high impact resistant optical plastic such as Trivex or polycarbonate to let as much light-in as possible.Acetate comes in a vast variety of colours, patterns and transparencies which make it one of the best polymers for spectacle making. a b Vincent Ilardi (2007).

A simple and convenient these nose glasses are a great affordable armless reading glasses solution which are lightweight and easy to carry.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.

These pince-nez have a C-shaped curved and flexible metal bridge which provides tension to clip the lenses on the wearer's nose. They were in wide use from the 1820s to the 1940s and were available in a variety of styles, ranging from the early nose-padless type of the 19th century to the gutta-percha variety of the American Civil War era and then on to the plaquette variety of the 20th century. An advantage of this variety was that one size would fit any nose. The bridges were subject to metal fatigue from flexing when repeatedly put on and taken off, so would frequently break or lose their tension. The separation between the lenses was not fixed and might not match the user's interpupillary distance when flexed to fit, and the lenses would rotate slightly when being placed on the nose, so that the pince-nez could not be used to correct astigmatism. The disadvantages made this type fundamentally flawed for many wearers.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 are a secondary item which use a separate glasses part called a pad arm. The pad arms are either inserted into an acetate/horn frame front or attached to a metal front via soldering. Once the pad arm is attached to the frame, a nose pad can be attached to end where it rests on your nose.
