is to temporary correct near vision in people with presbyopia.
Presbyopia occurs as a result of the natural aging process. As we age, the crystalline lens of the eye gradually stiffens and loses flexibility, resulting in the inability to focus on near objects.
CSF-1 is designed to improve near visual acuity by pupil modulation, resulting in a “pinhole effect” and an increase in the depth of field, thus increasing the ability to focus on near objects.
