11 eyeglasses parts you should know

eyeglasses parts

1. Front: the front part of frame

2. Rim wire: Fix the lens on the frame

3. Top bar: The top edge of the left and right mirror ring is connected to the aviator style glasses.

4. End pieces: the joints between the rim and the hinge, they are the small parts on the frame that extend outward and connect the lenses to the temples

5. Bridge: Connect the left and right rim wires or connect directly to the lens. Some acetate bridge is placed directly on the nose.

6. Hinge: Connect a joint of the pile head and the temple arm so that the arm can be folded inward

7. Rim lock: Loosen the screw to open the upper and lower rim wire for easy installation of the lens. The locking screw secures the lens.

8. Temple: The handle on both sides of the glasses

9. End tip: Cover the end of the temple

10. Pad arm: An adjustable metal material nose joint for connecting metal to soft nose pads

EYEGLASSES PARTS FOR EYEGLASS REPAIR

Due to everyday wear and tear your glasses can become loose, crooked or out of alignment.

Although you cannot repair all types of repairs on all types of glasses, It is still possible to fix eyeglasses for some common problems by DIY.

We know the values of glasses that you had invested in and our professional staff will help you get your glasses back in function.

The difficulty for eyeglasses repair is to find suitable eyeglasses parts and tools. We still try our best to offer you diversified glasses parts.

We will try to provide diversified parts from Eyepieces, endpieces, nose pads, temples, screws, cable temples to hinges and spring hinges.

EYEGLASS FRAME PARTS AND STRUCTURE

Eyeglass frames have two basic parts:

The frame front that holds the lenses

The temples that hold the frame from falling off your face.

THE BRIDGE AND NOSE PADS

Bridge width is the second number in the string (51-22-140) and is important in determining fit. The bridge measurement is the distance between the lenses.

If you have a narrow bridge or close set eyes you will want this number to be lower (15mm to 18mm) if you have a wider bridge or wide set eyes this number can be higher (20mm to 24mm).

Also consider the location of the bridge in relation to the browline of the frame.

Frames with bridges that are even with the browline are longer if the bridge of your nose is higher on your face (above your pupils).

Frames with a lower bridge and a more arched browline are shorter if the bridge of your nose is lower on your face (approximately even with your pupils).

Nose pads are easy to wear, tear and lost

Nose pads are attached to pad arms, which are welded to the frame front. Nosepad arms are made of a strong and endure metal so that they can be adjusted (bent) during a fitting. This metal is then welded on to the frame front which could be made of titanium, monel, stainless, or other materials.

Nosepads are attached either by a screw (screw-in nosepads), or they are push-in nosepads which require no screw.

Most nosepads are designed this way so that the nosepads can be replaced when they wear out.

LOOK! you can adjust nose pads arm to let frame fit you.

Acetate frames, and some metal eyeglasses frames do not have nosepads; they have a saddle bridge construction.

This term refers to a style of bridge in which the arched portion of the bridge lies directly on the bridge of the wearers nose. Saddle bridges are more common with plastic frames than with metal frames.

THE FRONT

The frame front is composed of two eyepieces connected by the bridge, Some glasses frames have single bridge and some have two which generally called aviator frames.

The eyepieces hold the lenses and connect to the temples by hinges

Rim wire

The Rim wire on a full-frame completely encircle the lens.

For metal frames, the rim wire is fasten together with a screw to hold lenses

For acetate eyeglasses frames, the rim is heated until it expands, the lens is snapped into position.

For half-rim frames, the lens in held in place by a nylon cord called the eyewire that attaches to the frame in two places.

For Rimless frames, the lenses are hold by bridge and temple.

ENDPIECES

The edge of each eyepiece extends out beyond the shape of the lens.

This part is called the endpiece, The component connected to this part is the hinge which holds the temples to the frame front.

TEMPLES

There are many different types for frame temples, which connect and hold the frames front to the wearers head behind and below the ears.

The most common is the skull temple, with the long straight shaft that is bent with an angle at the top of the ear near the end of the temple which is called the temple tip.

The shaft is the straight part that extends from the connection point at the eyeglasses frame front to the bend in the temple.

Library temples are straight all-shaft temples with no bend in them. Most eyeglasses frames' temples have temple tips that are adjustable so that they can be changed (bent) to adjust the fit of the glasses.

Temple tips are usually coated by acetate, molded silicone, plastic material that is designed to wear confortable for ears.

Some of plastic temple tips covers are designed to be replaced when wear and tear.

CABLE TEMPLES

Cable temples refer to curly temple tips, which curl behind your ears.

Cable temple hold glasses in place better and are a good choice for people in active situations and for children.

However, cable temples are not easy to adjust, and if they pinch your ear it is very difficult to adjust the temples as the metal is not designed to be adjusted easily.

HINGES

The most common type of hinges you will find are Standard Hinges.

Eyeglasses frames' hinges are used to connect the temples to the front of the eyeglasses frames, while allowing the temple to fold flat against the frame.

Most frames use external hinges, which are mounted on the inside of the temple shaft. Internal hinges are buried inside the shaft of the temple, hiding the mechanism from view.

These hinges work similarly to door hinges and are one of the oldest types of hinges found on glasses.

Standard hinges are made up of barrels that fit into each other like a zipper with a small screw that slides into the middle to keep the barrels in place.

This allows temples to move back and forth while still keeping them firmly attached to the frame front.

These simple hinges are found on a wide range of frames.

In general, the more barrels of hinge, the more durable your frames will be.

An average pair of glasses may have 3 barrels however, some manufacturers manufacture five and six barrel hinges.

Hinges are a small but very important component in the overall quality of your eyeglass frame.

If the hinge is not mounted on the frame properly, it will disengage which leads to a very difficult (or impossible) repair job.

SPRING HINGES

The second most common type of hinges that you will encounter are Spring Hinges (or “flex hinges”).

These hinges are equipped with a small spring that affords the arms a greater range of movement and does not limit them to the traditional, 90 degree angle.

These hinges provide greater comfort for the wearer and are more able to withstand everyday use.

Most Spring Hinges are constructed with 3 barrels.

These RayBan RX5268’s are a good example of the spring hinge.

A spring hinge is a hinge that is mounted on the temple shaft and allows for spring action. These hinges are equipped with a small spring that affords the arms a greater range of movement and does not limit them to the traditional, 90 degree angle.

These hinges provide greater comfort for the wearer and are more able to withstand everyday use.

Spring action hinges also help to keep frames properly aligned.

HINGELESS FRAMES

Hingeless eyeglasses have frames without hinges and these frames have no screws, no barrels, and no hinge!

Most of these frames are sculpted to fit the shape of the wearer’s head.

Frames use a very flexible material, usually titanium, for the temples.

The springiness of the temples lightly pinches your head to hold the glasses in place. Hingeless frames are often used for sports or high activity glasses.

This system results in a lighter weight pair of glasses, fewer components that could break, and a sleek design.
