When should nose pads be replaced?

01 · DISCOLORATION

Heavy discoloration is a reason to inspect the pad

Clear or translucent pads can become yellowed or cloudy with time.

Discoloration alone does not prove a functional problem, but it can indicate long use or accumulated contamination, so inspect the surface, elasticity and damage as well.

Discoloration can be a reason to inspect hygiene and material condition, but it should not be the sole replacement criterion. A discolored pad may still function if its surface is intact, it has no cracks or deformation and the fit remains comfortable.

02 · HARDENING

Check the pad if the contact feel has changed

Soft pads, including silicone-type products, can change in elasticity or surface feel after long use depending on formulation and environment.

If they feel markedly harder or more slippery than before and cleaning does not restore them, replacement may be reasonable.

Soft pads can change with age, becoming firmer or sometimes tackier at the surface. Because contamination can create a similar change in feel, clean the pad appropriately first, then assess elasticity, surface damage and actual contact.

03 · SLIPPING

If cleaning does not fix slipping, inspect both pad and fitting

Sebum and cosmetics can change the friction characteristics of the pad surface.

If the frame still slips more than before after cleaning, inspect pad condition but also check temple spread and other fitting changes.

To determine whether the pad is really causing renewed slipping, compare the entire fit before and after replacement. If the temples have spread or a hinge has developed play, a new pad alone may not restore the original stability.

04 · DAMAGE

Cracked or deformed pads should be replaced

Tears, cracks or damaged edges can irritate the skin.

If a pad repeatedly rotates abnormally or the mount feels loose, inspect the screw, pad box and pad arm as well as the pad itself.

A cracked pad can present a rough edge to the skin, while damage at the attachment can prevent the pad from maintaining its intended angle. If it repeatedly rotates or comes loose, inspect the screw, pad box and pad arm as an assembly.

05 · FIT AFTER REPLACEMENT

Refit after installing new pads

Even pads sold as the same size can differ slightly in thickness, curvature and material.

After replacement, recheck wearing height, vertex distance, contact area and left-right balance.

Even a replacement sold under the same nominal size can differ slightly in thickness, curvature or material. After installation, recheck wearing height, vertex distance, bilateral surface contact and pressure rather than stopping once the screw is secure.
