Nose Pads: Materials, Types & Shapes

nosepadsWhen it comes to nose pads, there are several materials, types and shapes to choose from. How do you determine which are the right ones for you? Here are some common descriptions to help you decide.

Materials

Silicone:  Soft plastic material. Very Flexible. Most popular style.

PVC:  A medium plastic material…not as hard as acetate and not as soft & flexible as silicone. There are 2 types:  Rigid & Soft.

  • Soft PVC:  Quite flexible and conform to the nose more than rigid PVC. Similar to silicone nose pads.
  • Rigid PVC:  Firm but not totally rigid.

Acetate:  A hard plastic material. Very Firm.

Bohemian Crystal:  Hypoallergenic. Clear, glass material with a polycarbonate post for patients who can’t wear plastic or metal.

Mounting Types

NP - mounting types

Screw-On:  Mount with hole for screw to hold in place.

Push-On:  Post snaps into place. No hole in post.

Primadonna:  Base has a “T” shaped hook. Looks like a snap-in nose pad and functions like a push-on nose pad, but only fits into primadonna pad arm.

A/T (mushroom) Monopad:  Wire at end of nose pad arm wraps around the “stem” of the nose pad post.

Snappy Pad:  Two protruding mounting posts on nose pad snap into two recessed mounting holes on plastic frame. Aka “Press-On Nose pads”. Low profile and usually non-adjustable.

Crimp-On:  Used for B&L Frames. Two metal fasteners wraps around metal nose pad mount on bridge of glasses.

Slide-On:  Round protrusion on back slides into a nose pad mounting arm on glasses. Often seen on rimless and semi-rimless frames. Bayonet shaped slide-on nose pads are used on Zeiss frames.

Adhesive / Stick-On:  Use an adhesive to adhere to frame. Most often used on plastic frames. Temporary and will need to be replaced periodically. There are 2 types:  foam and silicone.  Silicone adhesive nose pads generally last longer because they are more resistant to oils on skin and abrasion, and they repel most lens cleaners and water.

Shapes

NP - shapes

Round / Button:  Perfectly round shape. No difference between left and right.

Symmetrical Oval:  Most common shape. Football shaped. Looks identical from front and back. Right and left are interchangeable. Frame weight placed in center of pads.

Symmetrical Oval Tear Drop:  Wider at one end for better distribution of weight on the bridge. Right and left are interchangeable.

Symmetrical Round Tear Drop:  Same as symmetrical oval tear drop but with straight sides.

D-Shape:  Shaped like a “D”. Right and left are mirror images of each other and are not interchangeable. Flat front edge and curved back edge. Flat edge points away from the face. Frame weight distributed over a large area of the nose.

Saddle Strap:  Left and right nose pads are embedded into each end of the connecting strip. Connecting strip of silicone allows pressure to rest on bridge of nose as well as sides so frame feels lighter. Can be more comfortable than traditional left and right nose pads. Strap bridge is bent to conform to the eyeglass bridge and the wearer’s nasal area. Fits onto regular nose pad arms and are often used by eyeglass repair companies.

Softwing:  Shape resembles an upside-down “U”. Held into frame with two screws at top of nose piece. Wings are adjustable. Can be more comfortable than traditional left and right nose pads. Have a metal inner core. Similar to saddle strap but arms or pads only have limited movement.
