A method and apparatus for increasing the depth of focus of the human eye comprising a lens body, an optic located in the lens body, the optic configured to produce light interference, and a pinhole-like optical aperture substantially in the center of the optic. In a further embodiment of the invention, the optic is configured to produce light scattering. In a still further embodiment of the invention, the optic is composed of a light reflective material. The optic may also be configured to increase depth of focus via a combination a light interference, light scattering, light reflection and/or light absorption. In alternate embodiments of the inventions, the optic may be configured as a series of concentric circles, a weave, a pattern of particles, or a pattern of curvatures. A further method for increasing the depth of focus of the human eye includes screening a patient for an ophthalmic lens, the ophthalmic lens increasing the patient's depth of focus, using a pinhole screening device. In an alternative embodiment, the method comprises surgically implanting a mask in the patient's eye, the mask configured to increase the patient's depth of focus. |
