Abstract:
1. An apparatus for optometric self-examination, comprising: a database to store shape data of a plurality of contact lenses; an optometric data acquisition unit for determining at least a part of a shape of a cornea of a user in response to an operation by the user and acquiring optometric data, based on the shape of the cornea; a contact lens selection unit for selecting one or a plurality of contact lenses suited for the optometric data, based on the optometric data and the shape data of contact lenses stored in the database; and a contact lens data display unit for displaying a result of selection of a contact lens selected by the contact lens selection unit, wherein the optometric data acquisition unit acquires curvature data at a plurality of points on a surface of the cornea of the user the optometric data, and the contact lens selection unit calculates an average value from a maximum value and a minimum value among the curvature data at the plurality of points acquired as the optometric data and selects the one or a plurality of contact lenses based on the average value.
