End Piece

The end piece is the frame’s portion which extends the lenses. This frame connects the temple to make the shades stable. The glass end pieces are located at the frame's furthest edges.

End Pieces vary in size and shape, depending on the style of temples on your shades.

There are two common kinds of end pieces:

  • Full rim/half rim end pieces have recesses on their rear side to accommodate the hinges. These are called hinge graves, where a steel or plastic pin penetrates your frame material surface from behind and fastens with rivets passing through front surfaces for an easy install process without much fuss!
  • Rimless end pieces are actually part of the temple instead of the front. Beyond the hinge, another part is constructed of a lug metal, which generally bends at an angle close to 96°. The lug is screwed into place through your lens for stability with its firm connection intact no matter how many times you wear it or twist it around!

Nose Pad

Nose pads are pieces that help stabilize the position of the glasses on the wearer’s face. 

There are many styles, shapes, and sizes for this piece, so you should be sure to find the right one that will work with your frame front style!

They can either be part of a frame front material or as an extra metal piece called a padded arm: the piece controls the position of a nose pad which can be adjusted for comfort later. Most frequently found on metal and sports frames.

Bridge

The bridge is a vital component of your eyewear. It supports most of its weight and functions as an arched surface between lenses, designed to help distribute pressure from one point on your face (the nose) evenly across all other areas.

To do this, it has two main functions: a bump in between each lens and an aperture that allows more light inside so you can see clearly with fewer distractions outside.

Top Bar

The top bar, often known as a "brow bar" and a prominent element on aviator sunglasses, lays between the lens, giving you extra support when wearing glasses or contacts. 

Not all types have one, so be sure to check before buying!

Lens

Plastic or polycarbonate material that allows the user to see.

The most important part about your shades is the lenses. They help you see clearly, and come in many different types, some even made from glass!

Nowadays, most if not all glasses use high index plastic for better comfort and clarity! 

The process of fitting lenses is called glazing. Depending on the style of frame front you choose, different types of friction fit will be used.

Screw

Screws are little metal fasteners you can see located on the temple of your bifocals, connecting it to its end piece or screwed into place at either side where they'll hold up the nose pads.

The screws are what hold the hinge's two parts together.

You can tighten or loosen the opening of your temples with screws. One screw per hinge will help you achieve depending on how tight (or loose) their shades are adjusted for when worn.

Hinge

Hinge mechanisms connect the end piece to your temple and allow them to fold inward. Spring hinges can be an excellent option for those who have trouble finding the right fit.

The metal connections that allow you to open and close the glasses frame are known as hinges. They are also known as "joints" because they connect each temple to its matching front.

Temple

The temple is commonly known as the arm or legs of your sunglasses. It's there to keep them stable when you're wearing them and can come in many different styles depending on what look you want for yourself!

This piece is a relatively modern innovation. Old-fashioned frames didn't initially have temples and would rest on your nose or be held in place with handles instead.

Temple Tips/Earpieces

It is a plastic coating covering the temple, which lays on the top position to fill in for any gap. Earpieces make the wearer comfortable, that’s why they are included in metal-frame bifocals for extra wearing comfort!

The end of your temples is where you'll find the tips. These are farthest away from your frame and can come in various iterations to suit different tastes or needs for style!

Rim

The rim of eyeglasses is the frame’s portion that keeps the lenses from falling out.

Rivets

Rivets are tiny metal bits that hold your spectacles together.

They may be found in a securely attached cluster on the frame's front end piece, as well as near where it hinges outwards at the temples, nose bridge, or anywhere else there is an attachment point.

The riveting method, also known as staking, involves squashing, deforming, and widening the ends of rivets for better adhesion.

The number of rivets can vary between two-cluster or three-cluster arrangements, utilized equally for the frame and the temple, depending on the kind of hinge.

  • With two-cluster formations need a total of eight rivets (four for each side.)
  • With three-clusters a need a total of 12 rivets.
