ABSTRACT:
An eyeglass for improved vision that includes a light source mounted on the eyeglass pointing to an eye and a controller on at least one arm of the eyeglass. An eyeglass wearer can turn on the light source and increase an intensity of light emerging from the light source by using a thumb wheel in the controller. The light source causes a contraction of an iris of the eye thereby requiring a less part exposure of a lens of the eye. The less part exposure of the lens improves vision of the eyeglass wearer. The light source can be arranged to point at least one or both the eyes of the eyeglass wearer. The eyeglass can include a plurality of light sources in different positions that can be selectively turned on by the thumb wheel and can accommodate any suitable controller.
