e-Vision’s Smart Focus Optics technology allows the user to adjust focus with a touch of the finger. For people suffering from presbyopia (natural loss of ability to focus on nearby objects that occurs with age), a single pair of glasses or contact lenses can no longer provide them with clear vision at all distances. Although glasses with progressive or multi-focus lenses, such as bifocals or trifocals, have been developed, many people have problems getting used to these lenses because of their restricted field of vision.
