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.

One embodiment of the present invention accounts for individual anatomical variation when evaluating optical nerve fiber measurements. In one aspect, contextual information is used to compensate or correct measurement data. In another aspect, reference coordinates are remapped for improved comparison or visualization. In one embodiment of this latter aspect, the method uses measurements of nerve fiber capacity and maps of nerve fiber retinal service to improve sensitivity and specificity in eye function metrics. In one instance, we use the birefringence of nerve fibers to determine the orientation of the fibers within the RNFL. Orientation of the fibers about the ONH is indicative of the service provided by the fibers and is used to improve the interpretation of thickness measurements of the nerve fiber layer. Normalized nerve fiber measurements about the optic nerve head improve specificity and sensitivity as compared to the standard model. These improvements are a result of partitioning the normative database or modifying the measurement data prior to comparison. Statistics on normalized measurements of nerve fiber bundles also show improvements in specificity and sensitivity.
