Usually, after turning 40 years old, human eye will gradually become impaired, and gradually can't clearly see things in close distance. Reading glasses are then needed. The first generation of reading glasses only has one diopter in the lens, and the second generation has two diopters in the lens. But the second generation has safety problems, such as not being able to take the stairs or driving, so it was not even as popular as the first generation. Then the third generation reading glasses with progressive multifocal lenses were invented and have completely solved the vision problems of the middle-aged and elderly people.
One piece of lens could satisfy all the gradual vision requirement from near to far, so that users can read, watch TV and drive at the same time. Progressive multifocal lenses are very expensive to be produced at first, but with the maturity of technology and the increase in factories, prices are starting to become more available to more people. TAKEprogressive aims at developing a professional progressive multifocal eyewear brand that serves the vast majority of middle-class consumers. The frames are all natural materials and can even achieve “zero chemistry” as needed.
