Intraocular implants and methods of making intraocular implants are provided. The intraocular implants can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. In particular, the intraocular implants can include a mask having an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion such as a clear lens or aperture. This construct is adapted to provide an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The intraocular implant may have an optical power for refractive correction. The intraocular implant may be implanted in any location along the optical pathway in the eye, e.g., as an implant in the anterior or posterior chamber.

An exterior lighting device based on a light emitting diode in conjunction with an optic fiber is disclosed. The device has a cylindrical housing having a closed end and an open end. The light emitting diode is placed on the interior of the on the closed end of the cylindrical housing. A clear lens having one end in proximity with the light emitting diode and an opposite end with a flat surface is provided. A top cap is installed over the open end of the cylindrical housing. The top cap forms a water tight seal with the cylindrical housing using O-rings. A retaining plate is held in place between the top cap and the cylindrical housing. The retaining plate is locked with the flat surface of the lens thus holding the lens in place over the light emitting diode. An optic fiber has a receiving end held by the retaining plate in proximity to the light emitting diode and an opposite emitting end extending from a socket in the top cap. A coupling assembly sits in the socket in the top cap and holds the optic fiber in relation to the top cap.

This invention discloses a 3-D Phenomenoscope through which any 2-dimensional motion picture with passages of horizontal screen movement can be viewed with a 3-dimensional visual effect. The 3-dimensional visual effect is produced by the 3-D Phenomenoscope regardless of whether the motion picture was shot on regular or digital film; regardless of whether the presentation media is film, digital film, VCR tape, or DVD, and; regardless of whether the motion picture is viewed in the movie theater, home TV, Cable TV, or on a PC monitor. No special processing during production or showing of a motion picture is required to achieve the visual effect of the 3-D Phenomenoscope—so no new constraints are placed on the owner, producer, distributor, or projectionist in creating, distributing or displaying motion pictures. The 3-D Phenomenoscope are completely self-contained computer-actuated battery-powered spectacles or glasses that a viewer wears when watching a motion picture. When the 3-D Phenomenoscope glasses are activated the viewer will see lateral motion in a motion picture in 3-dimensions. When the 3-D Phenomenoscope is not activated or the glasses are turned off, or if the viewer is not wearing the 3-D Phenomenoscope glasses, then the viewer will see the motion picture unchanged and without any special effects. The preferred embodiment of the invention presents a method and system for a 3-D Phenomenoscope to view 3-dimensional special effects in motion pictures, and disclose a system by which ordinary 2-dimensional motion pictures can be viewed as a 3-dimensionsal experience. The 3-D Phenomenoscope achieves this by taking advantage of the well-known Pulfrich effect, by which passages of lateral motion of an ordinary motion picture will appear to the viewer in 3-Dimensions if the motion picture is viewed through right and left lenses that are configured with a clear lens and a light-reducing or darker lens. Ordinary eyeglasses are configured with: (a) Right and left lenses for which the degree of clarity or darkening of the lens can be individually controlled (b) Digital photo sensors (a digital camera) that can capture the viewed motion picture as successive images and convert the captured frames to digital images for processing (c) Computer processor to process the successive images and identify lateral motion synchronization events, and (d) Ability to provide individual control for the light-reduction or darkening of the right or left lens based on the identified synchronization events. In this way, the 3-D Phenomenoscope provides a fully self-contained apparatus that allow any motion picture to be viewed with the visual effect of 3-dimensions.

Disclosed is a sports training glasses for assisting a person training in a sporting endeavor requiring hand / eye coordination to focus on a specific object, such as a baseball or golf ball. The sports training glasses are comprised of a frame having a centrally disposed bridge. The bridge may be designed to rest directly on a wearer's nose, or to have engaged with it a nosepiece for resting on a wearer's nose. A pair of temple arms are articulated at either end of the frame by a flexible, integral hinge made of a shape memory material. A pair of opaque lenses are disposed along the lower edge of the frame, one opaque lens on either side of the bridge. An elongated slot, aligned horizontally, is disposed within each opaque lens. A sliding member engages with each opaque lens permitting horizontal translation behind the elongated slot. An aperture is disposed within the sliding member, within which may be disposed a transparent lens. A separate nosepiece may engage with the bridge to provide better comfort. The nosepiece is comprised of a soft elastomeric material having two lobes acutely conjoined at their upper ends, each lobe having a series of horizontal splines and a vertical tenon which engages with a vertical slot in the rear surface of the bridge.

Corneal inlays and masks and methods of improving vision of a patient with corneal inlays and masks are provided. Masks with an aperture can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. For example, a mask can have an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion, such as a clear lens or aperture. This provides an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The mask may also include nutrient transport structures that provide nutrient flow through mask to prevent nutrient depletion. These nutrient transport structures can be configured to concentrate nutrient transmission near a center region of the mask to provide more nutrient flow near the center region.

Pilot Director Lights (PDLs) mounted on the exterior of a refueling tanker aircraft (10) utilize light emitting diodes (LEDs) (213) as a light source to provide visual information to the pilot of an approaching aircraft (30). The PDLs may include a plurality of light emitting devices (200) arranged in arrays (123 and 124), each light emitting device (200) being configured to illuminate a particular symbol / pattern. Each light emitting device (200) may include a plurality of modular banks (210) of LEDs (213), which are configured to emit light through a clear lens (230) within a particular field of view. The PDL arrays (123 and 124) may provide visual feedback regarding the elevational and fore-aft position of the approaching aircraft (30) relative to the boom envelope (14) of the tanker aircraft (10).
