The main structure that holds the lenses and supports the glasses. It consists of two main parts: the front frame and the temples.
Frame Front Includes the following components:
Rims: These secure the lenses and define the glasses' shape—rectangular, square, circular, etc. Some styles feature no rims or half rims.
Bridge: The piece that connects the two eyeglass rims above the nose bridge, bearing the glasses' weight. Its length and design directly affect wearing comfort.
Nose pads: Positioned below the nose bridge, these rest against the nose to support and stabilize the glasses. Note that some plastic frames have built-in nose supports instead.
Pad arms: Small connectors between the rim and nose pad that allow adjustment of the nose pads to fit different face shapes.
Top bar: A connecting piece above the nose bridge that joins the two rims, typically found in aviator or fashion frames.
End pieces: Components on either side of the frame front that connect to the temples.
The long side arms that extend over the ears to secure the glasses to the face. Their length determines how well the glasses fit.
Joints between the temples and frame front that allow the temples to fold. Available in standard, spring, or interlock designs.
