Multifocal, one mirror and three functions

With the increase of age, the accommodation of lens begins to degenerate, and it is hard to see small things at close range. It is commonly known as "presbyopia". Especially those with myopia will feel the trouble of coexistence of presbyopia and myopia. Wear short-sighted glasses when looking far away, take off the glasses when looking near, or prepare two pairs of glasses with different degrees to use alternately, causing inconvenience. In particular, wearing traditional presbyopia lenses, the appearance looks old.

With the progress of lens manufacturing technology, Tianhe optics uses the free-form surface multi-point positioning processing technology to concentrate the presbyopia lenses needed for looking close and the short-sighted lenses needed for far seeing into one pair of glasses. A pair of glasses can not only see far but also look close. It not only avoids the trouble of changing different glasses, but also makes you look younger after wearing glasses!

Multifocal lenses can be divided into hard design and soft design; the varieties of hard design are: round top double light, contact double light, flat top double light; the varieties of soft design are: progressive multifocal lens.
