Short Description:

Progressive multifocal glasses were invented 61 years ago. Multifocal glasses solved the problem that middle-aged and elderly people need different luminosity to see objects at different distances and need to change glasses frequently. A pair of glasses can see far, fancy, also can see close. The matching of multifocal glasses is a systematic project, which requires much more technology than the matching of monocal glasses. Optometrists not only need to understand optometry, but also need to understand products, processing, adjustment of mirror frame, measurement of face bend, forward Angle, eye distance, pupil distance, pupil height, calculation of center shift, after-sales service, deep understanding of multi-focus principles, advantages and disadvantages, and so on. Only a comprehensive expert can comprehensively consider for customers, in order to match the right multi-focal glasses.

In terms of appearance, progressive lenses are almost indistinct from ordinary monocal glasses, and the dividing line cannot be easily seen. Because only the wearer can feel the difference of luminosity in different areas, progressive lenses are more suitable for friends who want to protect their privacy. From the functional point of view, it can take into account the need to see far, see, see near, see the distance is more comfortable, and there is a transition area, the vision will be more clear, so in the use of the effect of progressive glasses is better than bifocal glasses.

Production Introduction

3

The biggest problem with multi-focus solution is that you don't need to change your glasses frequently, and it is not suitable for you to look close for a long time. When introducing this lens, it should be explained that there is astigmatic region, which is a normal phenomenon. If you simply look at the close lens for a long time, the effect is not as good as that of the purely close monocal glasses.
