Eyewear Anatomy Diagram

We understand how to repair any frame on the market due to our in-depth knowledge of frames, frame components and materials.  Above you see a diagram of all the elements that go into an acetate frame, also called Zylo frame.  Each side of the referenced frame has 8 elements with the nose bridge joining both sides.

Learn the anatomy of eyewear to better understand caring for your glasses.

Temple Tips

Temple Tips refers to the part of the temple (side arms) that goes behind the ear to hold your frames in place.  Temple tips come in different forms to suit each eyeglass patient’s needs such as Skull Temple Tips and Cable Temple Tips. The Skull Temple Tips are the most popular and probably the type of temple tip that you yourself are most familiar with.  The Cable Temple Tips wrap around the ear securing the eyewear from falling off.  Cable Temple Tips are commonly used on children and active adults.


The Temples are often referred to as the “side arm” by patients asking for adjustments, eyewear repairs or modifications.  Temples also come in a variety of types referred to as Skull Temples, Cable Temples and Bayonet Temples.  Skull temples are the most familiar and traditional in eyewear today. The Skull Temple are the temples on eyeglasses and sunglasses that can be adjusted behind the ear.

 Frame Elbow

The elbow frame elbow is the part of the frame that connects the lens eyewire and the temple (Side Arm).  The frame elbow houses a hinge that attaches the frame to the temple (side arm) and may also include a fixed and loose eyewire barrel on most metal eyewear frames, which facilitate eyewear lens interchangeability. Elbow pieces come in two different type of set-ups on metal frames: Casted, and component based. The one piece casted frame elbow will only have the hinges and barrel housing already seamlessly built in. The component based frame elbow is the most commonly used elbow on metal eyewear frames. This eyeglass and sunglass frame elbow has individual hinges and barrels welded on. The component based elbow is easily repairable because each hinge or barrel can be removed if broken and a new one is welded on.

Top and Bottom Eyewires

The eyewires referes to any material part of the frame that encases the eyewear lens. The eyeglass and sunglass eyewire helps to hold the lenses in place in the frame.  The eyewires also help hold the lens axis point with lenses that have cylinder power. Frames with an eyewire only on top or bottom is often called a rimlon frame and glasses with no eyewire are called rimless eyewear.

  • Complete Frame: These eyewires have a bevel rest where the lenses sits.
  • Rimlon Frames: These eyewires have a void for a Figure 8 lining to compensate the groove in the lens for the nylon rope
  • Rimless frames: These eyewires have the elbow and nose bridge drilled and mounted onto the actual lens

Nose Pad Arm

The nose pad arm is the small metal piece that nose pads are affixed to.  Nose pad arms are standard on metal frames.  Most plastic frames do not have nose pad arms, but they can be modified to have a nose pad arms so that nose pads can be adjusted to make the eyewear frames may fit better on your face.

Nose Bridge

The nose bridge is the center of your glasses that connects both eyewires or lenses of your frame together.  Most metal frames have joining points from the eyewire to the bridge.  Plastic frames are one-piece molded nose bridge and eyewire.
