1.56 Progressive Anti-Fatigue Lens

The lenses are designed using microwave technology, allowing more natural eye accommodation and effectively relieving visual discomfort. The inner aspheric surface reduces peripheral aberrations, enhancing peripheral vision and overall visual clarity.

Relieving Accommodative Stress: When focusing on near objects, the ciliary muscle needs to continuously contract to adjust the focal length, which can easily lead to fatigue over time. Anti-fatigue lenses typically have a lower additional power (usually +0.50D to +1.25D) in the lower half to help reduce the accommodative burden on the eyes, similar to "miniature progressive lenses," but with a smoother accommodative zone.

Improving Visual Field Zones: The upper part of the lens is suitable for distance vision, the middle transition zone is for intermediate distances (such as computer screens), and the lower part is for near reading, making it easier for the eyes to switch between different distances.
