Sometimes they need to be adjusted by professionals.

Some connecting parts of glasses will be loose, but some people do not care about them and make casual changes. In reality, the change of the lens frame is very technical. The distance between the lens and the glasses will affect the effective strength of the lens, so the adjusted glasses need to be 12 to 14 mm away from the eye. The optical center of the lens should be aligned with the pupil position, and the nose pad, the temples should be consistent with the contact part of the bridge of the nose and the ear, without pressure and pain. Therefore, the lens frame must be adjusted by a professional optician. Especially some special lenses (progressive multi-focus glasses) need to be repaired regularly.


Why choose an acetate frame?

(1) Lightweight and comfort

As one of the daily necessities, the lightweight acetate frame will not bring a heavy burden to the bridge of the nose. Even if you need to wear glasses all day, you will not feel too much discomfort.

(2) Durability

This is the key factor that makes acetate frames stand out from traditional plastics or other materials. Acetate frames are made by cutting, molding and polishing multiple pieces of material, which makes them as strong as metal and ideal for eyeglass frames.

(3) Various design

The cellulose acetate spectacle frame design is the most fashionable. The surface layer of the traditional plastic frame is usually sprayed with colors and patterns. It may have a nice design or color. But because it is the only surface, daily use will cause its surface color and pattern to fade. After a year or even a few months, their appearance may not be as good as before. Unlike plastic spectacle frames, acetate makes the design easier to retain. The acetate fiber sheet can be designed with colorful patterns, different layers, and many colors. The embedded design can maintain its characteristics more effectively without spraying or painting.

Acetate is comfortable, weight-light and fashionable, and meets all your needs. Therefore, it can be said to be the best material for making spectacle frames. Therefore, the next time you decide to buy a new spectacle frame, please consider using a spectacle frame made of acetate.
