ELECTRONIC DEVICE AND INFORMATION PROCESSING SYSTEM
The present invention provides technology by which the risk of data destruction during data transmission can be further reduced. On the basis of sensor information, a data block generation unit 32g generates a data block BD1, a data block BD2, and a data block BD3. A first processing unit 33g generates second association information FT1, and appends the same to the data block BD2 as first association information HD2. A second processing unit 34g generates second association information FT2 including at least a hash value obtained from the data block BD2, and appends the same to the data block BD2. A storage control unit 36g executes control whereby the data block BD2, to which the first association information HD2 and the second association information FT2 have been appended, is correlated to at least one other unit of data, including the data block BD1, by using blockchain technology, and stores the same in a storage unit 12g. The abovementioned problem is thus solved.
A soft contact lens has low water content or no water content. The soft contact lens includes: a circular central part positioned at a center of the soft contact lens; an intermediate part positioned at an outer peripheral side of the central part and forming an annular shape having a center coaxial with the central part; and an outer edge part positioned at an outer peripheral side of the intermediate part and forming an annular shape having a center coaxial with the central part. Respective radii of curvature of the central part, the intermediate part, and the outer edge part are different from each other, and a sagittal depth of the soft contact lens is within a range of a sagittal depth in a case where the entire soft contact lens is formed in a range of a radius of curvature ±0.2 mm of the outer edge part.
This contact lens is provided with a concave inner surface that comes into contact with a subject's eye, and a convex outer surface, and is provided with an incidence-side light guiding window that is formed to be cut from the outer surface to the inner surface side, and guides light incident from a direction approximately orthogonal to a lens geometric center axis such that the light travels along the direction approximately orthogonal to the lens geometric center axis in the aqueous humor of the subject's eye wearing the contact lens. Consequently, provided is the contact lens that makes it possible to noninvasively analyze a substance contained in the aqueous humor of the subject's eye.

As the results of an enthusiastic gene analysis on samples collected from a great number of severe myopia patients and normal subjects who are Japanese with a high prevalence of severe myopia, the present inventors identified nine single nucleotide polymorphisms (SNPs) which correlate at a genome-wide significance level with severe myopia. The SNPs that significantly correlate with the onset risk of severe myopia can be considered as SNPs exerting a high genetic effect on the onset risk of myopia. By using these SNPs as an indicator, the genetic influence on the onset risk of myopia can be more appropriately evaluated.
