Common vision adjustment glasses include frame glasses and contact lenses, which are suitable for different groups of people. What kind of glasses do you like? Different glasses have different benefits.
Let's take a look at the difference between spectacles and contact lenses.
1. Frame glasses.
A complete pair of frame glasses usually consists of main components such as lenses, rims, nose pads, tips, and temples.
The replacement time of the frame glasses.
Frame glasses are generally replaced every 1-2 years. The lenses can be replaced every 2 years or so depending on the material, while the frames can be replaced once a year or more depending on the deformation.
The specific replacement time is uncertain, but from the perspective of eye protection, the eyes and vision should be checked within 1 year before deciding whether to replace the glasses.
If your glasses are clearly not matching your vision, you should change them as soon as possible. Do not use a pair of glasses for extended periods of time without checking or changing them, as this can easily damage your eyes.
