An eye mask has magnetic bodies and self-heating warm members, which are inserted in eye pads on a mask member to be placed over eyeball parts. If required, vibrators and illumination bodies may be additionally placed in the eye pads. Thus, fatigue on the eyes and surroundings thereof can be relieved by the magnetic actions of the magnetic bodies and the warming effects of the warming member, in addition to expected effects of restoring ocular functions, recovering from various ocular diseases, and so on. Furthermore, the surface of each of the eye pads is gradually curved like the inner surface of a sphere. When the eye pads are press-contact to the eyeball parts at predetermined pressures for a long time, the cornea can be warmed by the warming members so that the shape of the cornea can be changed along the shape of the eye pad, resulting in the effects of recovering from eye sight disorder such as pseudo-myopia, moderate farsightedness, or moderate astigmatism.

Provided herein are intracorneal inlays for correcting vision impairments by altering the shape of the anterior corneal surface. The physical design of the inlay to induce the desired change of the anterior corneal surface includes consideration of the biomechanical response of the corneal tissue to the physical shape of the inlay. This biomechanical response can differ depending on the thickness, diameter, and profile of the inlay. In one embodiment, inlays having diameters smaller than the pupil are provided for correcting presbyopia. To provide near vision, an inlay is implanted centrally in the cornea to induce an “effect” zone on the anterior corneal surface, within which diopter power is increased. Distance vision is provided by a region of the cornea peripheral to the “effect” zone. In another embodiment, small diameter inlays are provided that induce “effect” zones on the anterior corneal surface that are much larger in diameter than the inlays.

Provided herein are small diameter inlays for correcting vision impairments by altering the shape of the anterior corneal surface. In an embodiment, inlays having diameters smaller than the pupil are provided for correcting presbyopia. To provide near vision, an inlay is implanted centrally in the cornea to induce an “effective” zone on the anterior corneal surface, within which diopter power is increased. Distance vision is provided by a region of the cornea peripheral to the “effect” zone. In another embodiment, small diameter inlays are provided that induce effective optical zones on the anterior corneal surface that are much larger in diameter than the inlays. The increase in the effective optical zone, due at least in part to a draping effect, allows an inlay to produce a much larger clinical effect on a patient's vision than the diameter of the inlay.

This invention is for directly modulating a beam of photons onto the retinas of patients who have extreme vision impairment or blindness. Its purpose is to supply enough imaging energy to retinal prosthetics implanted in the eye which operate essentially by having light (external to the eye) activating photoreceptors, or photo-electrical material. The invention provides sufficient light amplification and does it logarithmically. While it has sufficient output light power, the output light level still remains at a safe level. Most preferred embodiments of this invention provide balanced biphasic stimulation with no net charge injection into the eye. Both optical and electronic magnification for the image, as for example, using an optical zoom lens, is incorporated. Otherwise, it would not be feasible to zoom in on items of particular interest or necessity. Without proper adjustment, improper threshold amplitudes would obtain, as well as uncomfortable maximum thresholds. Therefore, to adjust for these, a way of proper adjustment for the threshold amplitudes and maximum comfortable thresholds is provided. Furthermore, to the extent that individual stimulation sites in the retina give different color perceptions, upon stimulation, then colors of the viewed scene is correlated with specific stimulation sites to provide a certain amount of color vision.
