LENS CONTROL APPARATUS, OPHTHALMIC LENS APPARATUS, SPECTACLES, AND CONTROL METHOD

Abstract: a focal length of a variable focus lens is adjusted with high precision to match a focus of each individual user according to a distance to a view object. a lens control apparatus, which controls a focal length of a variable focus lens for eyes, includes a storage portion for storing focal-length-specifying-information for specifying a focal length of the variable focus lens according to a distance to a view object, a control portion for controlling a focal length of the variable focus lens based on a detection result of a distance detection portion that detects the distance to the view object and the focal-length-specifying-information in the storage portion, and a setting process portion for executing a setting process in which a distance to each of setting-use view objects located at multiple different distances when the user of the variable focus lens views the respective setting-use view objects, and the focal-length-specifying-information generated based on each focal length of the variable focus lens at which the user focuses on each of the setting-use view objects, are stored in the storage portion.
