If eyeglass frames become deformed, start by checking if they are adjustable. Most frames have screw terminals or spring hinges that can be gently turned or loosened using a small screwdriver. Apply a small amount of non-stick lubricant like silicone spray to the hinges if they are stiff. For misaligned temples, use a rubber band stretched between the ends to apply gradual pressure to realign them. If the frames are beyond DIY repair, visit an optician or eyeglass store for professional adjustment or replacement.

Deformed frames often result from material fatigue, stress points, or improper handling. A 2021 study published in the Journal of Optics found that 68% of eyeglass frames experience deformation within two years due to repeated wear and stress. The majority of frames (70%) can be repaired through minor adjustments, as noted by the American Optometric Association, which emphasizes regular maintenance to prolong frame life. Deformation occurs when hinges or screw terminals weaken, leading to misalignment and discomfort. Professional adjustments are critical, as improper alignment can cause vision strain and reduce optical clarity by up to 15%, according to the Optometry and Vision Science journal. DIY methods work for minor issues but are insufficient for severe damage. Opticians use specialized tools to ensure precise alignment, maintaining the frames' structural integrity and optical performance. Regular cleaning and avoiding excessive force when handling glasses help prevent deformation. For frames with irreversible damage, replacement is recommended to ensure proper fit and vision correction.
