Frame warpage is a deformation where the spectacle frame front or the temple arms lose their original shape. The frame becomes bent, twisted, or distorted, making it impossible to sit straight or level on the wearer's face.
read more about eyeglass frame warpage ...Frame warpage is mainly caused by improper heat exposure. Leaving plastic frames in a hot car, on a car dashboard, or near a heating vent can soften the material and cause it to permanently twist out of shape.
Warpage severely affects visual clarity. A twisted frame causes the lenses to be misaligned, forcing the eyes to compensate for the distortion. This misalignment quickly leads to eye strain, blurriness, and headaches.
Opticians correct warpage by applying controlled heat (using a frame heater or salt pan) to the affected area. The optician then uses specialized tools to gently reshape the frame back to its original plane. This correction requires skill and patience.
Maintaining a straight, unwarped frame is important for your backup glasses. A warped frame provides distorted vision. Keeping your frame integrity makes sure you have clear, comfortable sight when your contacts are removed.
Yes, metal frames can warp, but usually from strong physical force or twisting, rather than from common heat exposure.
Minor warpage is often fixable. Severe warpage, where the plastic is brittle or melted, cannot be fixed.
Always store plastic frames in a protective case and never leave them exposed to direct sunlight or high heat (like near a window or car dashboard).
A warped frame changes the "vertex distance" and "tilt" of your lenses, effectively changing your prescription power. If your vision feels "wavy" or blurred, your frames may be warped. Do not use a hairdryer to fix them; an optician must use a calibrated frame warmer.
