Advantages of 1.56 Progressive Lens Multifocal Optical Lens Wholesale

Relieve eye fatigue: The progressive lens design enables a more natural transition from near to far vision, reducing the burden on eye adjustment and effectively alleviating eye fatigue.
Control the progression of myopia: For myopia patients, progressive lenses help control the further deepening of myopia by reducing the pressure on the eyes from prolonged near work.
Eliminate eye soreness and swelling: Long-term use of single vision lenses may cause eye soreness and fatigue. Progressive lenses, by providing a smooth transition between different focal lengths, help alleviate these discomforts.
Convenient to use: Progressive lenses combine the functions of both near and far vision lenses, eliminating the hassle of frequently changing different pairs of glasses. Patients can see distant objects through the upper part of the lens and nearby objects through the lower part.
Aesthetic: Compared with traditional bifocal lenses, progressive lenses have no obvious dividing lines and look more aesthetically pleasing.
