But in fact, glasses also have a lifespan.

The use time of a pair of glasses is related to our usual life, work and eye use, maintenance degree, the general normal use time of me about 2 years, glasses are composed of frames and lenses, the raw material of the lens is resin, the lens itself only has diopter, does not have the function of protection, the lenses sold to consumers are used after adding various films, but the film is not resistant to high temperature, scratches, but also to help the eyes sunscreen, the lens will be due to external factors, the film cracks, lens scratches, Yellowing, color deposition, etc., membrane cracking directly affects the vision, and in severe cases, it will affect the eyesight and cause the degree to deepen. Lens scratches are also the most common lens problems, especially after the optical center of the lens is scratched, which directly affects the diopter of the lens.

The second part is the frame, the frame material is generally metal and injection molding materials are common, the most fatal problem of the metal frame is the fear of pressure, once the frame is pressed to the deformation can not be recovered, there is an imbalance in wearing, in addition to the surface of the color and glasses desoldering, falling off, being corroded and broken by sweat and other problems, the normal use of metal frames will generally appear in 1 year will appear slight discoloration, special workers will appear in a shorter cycle.

Injection molding frames are very unfriendly to temperature, not resistant to high temperature or low temperature, easy to deform at high temperature, easy to harden and break at low temperature, although the color of the plate frame will not fade due to sweat, but the TR90 frame with slightly worse technology will also fade, and his fading is a large area, which affects the appearance very much.

To sum up, what problems occur with the glasses are the alarm that it is time to change.

Lenses: The lenses have been used for more than 2 years, and it is obvious that the clarity is reduced, the ** layer on the surface of the lens is peeled off or cracked, the optical center of the lens is seriously worn, and the lens is yellowish and precipitated.

Frame: The frame is seriously deformed and cannot be recovered, the accessories are broken, the frame is seriously discolored (especially in the position of contact), and the frame is hardened and cracked.

However, it is not recommended to exceed 2 years depending on the degree of wear and tear of the lenses.
