Are glasses consumables

Glasses are consumables to a certain extent. From the perspective of daily use, lenses are easy to be contaminated with dust, oil, and fingerprints, and during frequent wiping, even if soft lens cloth is used, it will inevitably leave subtle scratches, which will accumulate for a long time, which will affect the clarity of the lens and reduce the visual quality. The frame will also be squeezed and pulled by external forces due to long-term wear, and deformities, such as loose temples and dislocated nose pads, which not only greatly reduce the wearing comfort, but also may affect the relative position of the lens and the eye, thereby interfering with the vision correction effect.

In addition, an individual's vision condition can change over time. Especially for teenagers, the body is in the stage of rapid development, the myopia degree is growing rapidly, and the original glasses often cannot meet the needs and need to be replaced in time. Adults with poor eye habits and aging may also have fluctuating vision, and they also need new glasses. In addition, the service life of glasses is also affected by the material, such as plastic frames may become brittle due to aging, and metal frames will oxidize and fade. Generally speaking, whether it is from the perspective of wear and tear, vision adaptation, material aging, etc., glasses have the characteristics of consumables.
