As we grow older, the lens of the eyeball gradually hardens and thickens, and the adjustment ability of the eye muscles also decreases, resulting in a decrease in zoom ability and difficulty in near vision, which is presbyopia. From a medical point of view, people over the age of 40 have gradually begun to show symptoms of presbyopia, such as decreased adjustment ability and blurred vision. Presbyopia is a normal physiological phenomenon. Each of us will have presbyopia when we reach a certain age.

What Are Progressive Lenses?
Progressive lenses are multi-focal lenses. Different from single-vision lenses, progressive lenses have multiple focal lengths on one lens, which are divided into three zones: distance, intermediate, and near.


Who Uses Progressive Lenses?

•  Patients with presbyopia or visual fatigue, especially workers with frequent changes in distance and near vision, such as teachers, doctors, computer operators, etc.
•  Myopic patients over the age of 40 begin to have symptoms of presbyopia. They often need to wear two pairs of glasses with different degrees of distance and near vision.
•  People who have high requirements for aesthetics and comfort, and people who like to try new things and are willing to experience different visual effects.


Benefits of Progressive Lenses
1. The appearance of progressive lens is like a single-vision lens, and the dividing line of the power change cannot be seen. Not only is it beautiful in appearance, the most important thing is that it protects the age privacy of the wearer, so there is no need to worry about revealing the age secret by wearing glasses.

2. Since the change of lens power is gradual, there will be no image jump, comfortable to wear and easy to adapt to.

3. The degree changes gradually, and the replacement of the adjustment effect also gradually increases according to the shortening of the near vision distance. There is no adjustment fluctuation, and it is not easy to cause visual fatigue.
