A Description of the Parts of Prescription Glasses

Lenses

• Corrective lenses in prescription glasses are usually made of plastic, according to the Cleveland Clinic. Common types of lenses include single-vision, bifocal and progressive. Single-vision lenses have one prescription for basic eye problems. Bifocal lenses have two different strengths separated by a dividing line. Progressive lenses have multiple strengths but no dividing line.
  
  

Frame Front

• The frame front includes rims that hold the lenses and a bridge across the top of the nose. End pieces extending down from the frame front are hinged to temple pieces.
  
  

Bridge

• The bridge sits over the nose and supports most of the weight of the glasses. Bridge styles include keyhole, saddle, adjustable and double. Keyhole bridges are appropriate for people with smaller noses. Saddle and double bridges offer more stability for heavier glasses. Adjustable bridges offer the most flexibility in wear.
  
  

Temples

• Temples are the frame parts that curve behind the ears to hold the glasses on your face. Temple styles include skull, comfort-cable, riding bow, spring-hinged, and paddle. Style differences include material and degree of curve.
  
  

Nose pads

• Plastic nose pads are often attached to the interior rims of the frame front. The pads increase comfort and help the glasses stay positioned on your face.
