What to do if the inner side of the titanium alloy glasses leg is dented
Titanium eyeglass frames are popular for their lightweight and high-strength features, but indentations on the inner sides of temples often cause ear or temporal pain. This issue mainly arises from structural design, wearing habits, or individual differences. Here's a concise guide to effectively alleviate the discomfort.
Causes of Indentation Pain
Structural Design Issues
Mismatched temple curvature: If the temple arc doesn't fit the ear contour (e.g., excessive inward bending at the end), it may press against the posterior auricular soft tissue.
Narrow temple spacing: Fixed opening angles in some lightweight frames can laterally compress the temples if head width doesn't match.
Abnormal hinge angle: Over-tight or loose hinges may tilt temples, causing prolonged friction on specific skin areas.
Material and Surface Treatment Factors
Hardness and edge finish: Pure titanium or β-titanium temples without rounded edges (R-angle) or with rough sandblasting may directly press or rub against the skin.
Stress residue in memory metal: Repeated adjustments to titanium-nickel alloy temples can cause micro-deformations, reducing contact area and increasing pressure.
Wearing Habits
One-handed removal: Single-handed use may deform temples, shifting indentation positions.
Prolonged wearing: Sweat or oil increases friction between temples and skin, aggravating pain.
Effective Solutions
Basic Buffer Measures (for mild indentations)
Silicone pads/ear covers: Attach 0.5-1mm medical-grade silicone pads to the indented area to disperse pressure. For posterior auricular pressure, add L-shaped ear hooks.
Fleece wrapping: Wind breathable fleece tape around inner temples to reduce friction and absorb sweat.
Temple curvature adjustment: Heat the indented area with a hairdryer (60-80℃) for 10-15 seconds, pad with a soft cloth, and gently reshape the curve. Set the shape with cold water.
Structural Optimization (for moderate to severe indentations)
Hinge adjustment: Use a 0.5mm hex key to loosen tight hinges (≤15° rotation) or tighten loose ones (torque 0.2-0.3N·m).
Temple spacing expansion: Gently bend temples outward (1-2° each time) to widen the spacing,ensuring symmetry (standard opening angle: 145-150°).
Surface polishing: Sand inner temple edges with 600-1000 grit sandpaper, then polish to form a 0.2mm R-angle. For better results, apply a skin-friendly PU or nano-ceramic coating.
Prevention and Management Tips
Wearing habits: Remove glasses with both hands to avoid deformation; take 1-2 hour breaks to massage pressured areas.
Purchase suggestions: Choose β-titanium or titanium-nickel alloys for better elasticity; check for rounded inner edges and anti-slip textures.
Skin irritation care: If indentations cause redness or allergies, clean with saline, apply hydrocortisone ointment, and switch to glasses. Persistent issues may indicate nickel plating-replace with pure titanium frames.
With proper adjustments and habits, most indentation problems can be resolved. For persistent pain, consult professional opticians to prevent further damage.
