MC glasses (Multifocal Progressive Glasses) designed for teenagers are thinner, less fragile and safer than ordinary resin lenses. MC glasses (multifocal progressive glasses) have the following effects: 1, there is a super wide distance zone, so that children can wear them comfortably whether studying or outdoor activities. 2.With a wide near-use area, children not only feel comfortable when reading a book but also have a wide field of vision. 3.With the short progressive band, children can read/study through the near-use area with just a slight downward turn of the eye. 4, MC lenses with small frames can effectively correct the child’s sitting posture! Because there are image dispersion zones on both sides of MC lenses, when children tilt their heads or squint their eyes to read books, they will feel blurred vision, and it forces them to return to the correct reading posture to get clear images. 5, years of clinical observation, if you can wear MC glasses for a long time, can indeed control the development of myopia in some primary and secondary school students.
