What are the parts of an eyeglass frame?
- Frame Front: Front part of the eyeglass frame that holds the lenses in place and bridges the top of the nose.
- Eye Wires (rims): Part of the frame front into which the lenses are inserted.
- Bridge: The area between the lenses that goes over the nose and supports 90 percent of the weight of the eyeglasses.
- A keyhole bridge is shaped like an old-fashioned keyhole and rests on the sides of the upper part of the nose. This style is for those with small or flat nose bridges.
- A saddle bridge is shaped like a saddle and spreads the weight of the frame across the sides and the top of the nose. This style works well for heavy glasses or for those who are sensitive to pressure.
- An adjustable bridge includes nose pads that can be adjusted for fit and comfort.
- A double bridge has a reinforcing bar over the top of the bridge.
- End Pieces: Extensions of the frame front to which the temples are attached.
- Hinges: Part of the frame that connects the frame front to the temples and allows the temples to swing.
- Temples: Parts of the frame that extend over and/or behind the ears to help hold the frame in place.
- Skull temples are the most popular for plastic frames. They are bent down slightly over the ear and follow the contour of the skull.
- Comfort-cable temples hook behind the ear with a flexible metal cable and are good for children's glasses and for sport safety glasses.
- Riding bow temples are similar to comfort-cables, except they are rigid and made of plastic.
- Spring-hinged temples include hidden springs in the hinges that help keep the frame from slipping. They are sometimes more expensive, but usually more resistant to breakage.
- Library (or paddle) temples are straight, so they can be slipped on and off easily. They are often used in reading glasses.
- Nose Pads: Plastic pieces that may be attached directly to the frame or to pad arms. They help keep the frame in its proper position.
- Adjustable Nose Pads: These pads provide maximum comfort by distributing the weight more evenly on the nose and eliminating uncomfortable pressure points. The pads keep the Glasses secure and prevent them from sliding down the nose.
- Pad Arms: Attachments that hold the nose pads in place and allow adjustments to help conform to the patient's bridge.
- Top Bar: A reinforcing bar that crosses the top of the glasses on some metal frames, popular in aviator glasses.
- Temple Tips: Plastic coatings that often cover the ends of the temples behind and/or over the ears.
- Rimless Frames (or mountings): Designed to provide precise peripheral vision, is distortion-free and offers an enhanced visual field.
- Side Safety Shield: Shield provides additional vertical and horizontal coverage and prevents impact-related injuries by dispersing the impact over the entire surface, protecting the orbiting facial area from lacerations and fractures. It is recommended for work requiring impact resistance and side protection from flying objects.
- Titanium: A very strong, but lightweight compound that is highly corrosive-resistant. It remains stable under high temperatures.
- Wrap Around Frame Design: Streamlined and sporty design offers perfect protective wear for both men and women. A wrap around design allows for good fit, ensuring worker compliance.
