The forms of attachment of two independent filters (15-16) for this embodiment are conventional and well-known (mechanical assembly, thermal soldering, etc.). A new brand called Ombraz this week launches sunglasses without ‘sidearms.’ They are very unique, and we received a sample to put them to the test.

Over-tightening your glasses screws may damage the fine threads, either in the hinge tenons or on the screw shank. Take care to avoid this. 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. The necessary element due to its optical properties can make up everything that is required: the optical system, the frame, the plate, the elastic element and the axis of its rotation. In other possible embodiments, the said glasses can be made of two suitable sheets, obtaining two parts, which should only be connected so as to obtain the necessary glasses to meet specific needs, for example, to observe three-dimensional stereoscopic images using additional filters that share the perception of each eyes making them independent. 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.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. Your hinges are the metal joints which allow you to open and close the temples on your glasses frame. John Keillor. Les valses (3) distinguées du précieux dégoûté (3 distinguished waltzes of a disgusted dandy), for piano at AllMusic Frame front | Endpieces | Bridge | Lenses | Temples | Temple tips | Hinges | Screws | Nose pads | Rivets | Other parts of glasses 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.

If you're adjusting plastic frame glasses, make the plastic pliable by warming it up in hot or warm water before bending it. 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. Instead, the two little "lugs" under the base-plate act like tree roots in the acetate frame front. Because they're barbed, they create an undercut which makes them more stable. The following numbered list is provided for the various sections of the invention that can be seen in the attached drawings: (10) glasses, (11) optical properties, (12) plates, (13) jumper, (14) joint area and plate connection area (12) with the region (11) of optical properties, (15-16) independent filters, (17) tabs, (18) junction point of the bridge (13), (19) external elastic element, (20) bending lines, (21) cut line, (22) the area of twisting, (23) the area for the brand, number or sign.

Sometimes entirely hidden within the acetate, they're used to reinforce your glasses temples to prevent them from losing their shape. Metal temple tips are usually covered or coated with plastic or rubber to make them more comfortable. However, our uni-piece temple design is cylindrical in form and tapered which reduces the need for additional parts and makes them incredibly easy to wear.

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. 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. Be sure to bend the frame on an adjustable part of the temple: directly at the hinge or at the bend at theear. The difference between Oxford spectacles (or "Oxfords" for short) and the pince-nez is not frequently drawn. The style was supposedly developed in the 19th century when a professor at Oxford University accidentally broke off the handle from a pair of lorgnette spectacles and reputedly affixed two small nose-pads to the frame and found that he could use the tension in the folding spring to perch them on his nose, though the authenticity of the story has never been verified. Oxfords are descended from the lorgnette, as early examples of them often had handles in addition to nose-pads. In style Oxfords are much like the C-bridge as the tension is provided by a flexible, sprung piece of metal; however, they also resemble the astig, as the spring connecting the two lenses is distinct from the nose-pieces. Oxfords were popular in Europe and the Americas up until the 1930s.Hidden hinges are identical to tenon hinges, except they have no additional fasteners such as rivets. Note: I’d originally wished the brand had a less premium offering so people could try them out without the financial commitment. Seems like the wish is granted, at least for early adopters.) The strap seems like it could be a problem for long hair. It would require some hair adjustment, and the knots can pull hair during the adjustment.
