Product Information

Since the plates act on the nose, they also experience an equivalent reaction force on both halves of the glasses, which leads to their rapid deformation. The material used for their implementation can help limit the deformation produced by the stress experienced by the plates by implementing various configurations that resist the deformation by processes such as thermoplastic molding, pressing, bending, casting or applying, which guarantee the necessary resistance and shape stability. Similarly, it is possible to use for such resistance the advantages of an anisotropic material that can be deformed in a given direction.

Remember that you only want to do this with traditional wire or plastic glasses. Not all plastic-rimmed glasses can handle the adjustment, even after warming them. You should never adjust rimless and semi-rimless glasses at home. When to Take Your Glasses to a Professional Another name for your glasses hinges, a fully assembled joint comprises of two half joints held together with a dowel screw. Seems logical…but the proper name for them is temples, simply because they locate on each side of your head.

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.

Metal bridges are used for either rimless frame fronts or for acetate “split frames.” For acetate split frames, a conjoining piece of metal is riveted or screwed into the separate acetate rims to join them together. Nose pads like these are very robust and can be adjusted by filing the acetate or horn away to reduce their height. To make them smooth again, the nose pads require hand polishing so they aren’t rough on your nose. Figure 4 is the external shape of another possible implementation, and a possible cut line is shown as made on a flat surface to obtain glasses with an external "C" -shaped elastic element.In the images above, you can see the characteristic cross head at the top of each of the screw-heads. Interestingly, temples are actually relatively modern as old-fashioned glasses didn’t originally have them. Instead, these old styles of glasses without temples just rested on your nose or were held to the face via a handle. This incredible material is a natural compound which derives from the fibres in cotton 'bolls' or mashed up wood pulp. 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

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.FIG. 7 is a front view of another possible embodiment after attaching two independent filters in accordance with FIG. 6. Whether they're fitted to sunglasses or spectacles, side shields have a fairly basic function. They close the gap between the edges of the frame front and your face. If the user who has already used refractive glasses, additionally requires another optical element, for example a filter, he can use glasses made in accordance with this invention, placing it in front of the glasses. The fixing of these glasses can be realized in this case, in addition to the plates 'own pressure, by the possibility that they can remain below the glasses' supports and take advantage of their weight on the user's nose. Examples of a concave and a convex lens. These lenses are actually made from glass but most modern lenses are made from CR39 plastic.
