Vision can be easily improved by using pinhole glasses. The pinhole phenomenon allows you to look through many small holes and adjust the focus of your vision by changing the thickness of the crystalline lens. The "ciliary muscle" plays a role in this adjustment. When the ciliary muscle works correctly, both near and far objects will not be blurred, and you can see smoothly. 【Vision Recovery】 Convenient pinhole glasses that allow you to easily perform near and far vision recovery training are now available! Improves eye muscle strength! Relaxes the ciliary muscle! Strengthens the iris muscle! By adding exercises such as opening and closing your eyes and moving your eyes up, down, left, and right, you can also improve the "blood flow of the eye muscles and reticular muscles," which is important for vision. 【Applicable Target/Scene】 Applicable target: Nearsightedness, presbyopia, astigmatism, for those with eye problems!
