【発明の詳細な説明】
〔産業上の利用分野〕
本発明は眼鏡、特に自動的に焦点調節ができる眼鏡に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to eyeglasses, and more particularly to eyeglasses that can automatically adjust their focus.
従来、眼鏡装用の目的は特別な目的で使用されるサング
ラス等のファッション眼鏡を別にすれば近視、遠視、老
視等の屈折力矯正にある。しかしこれらは単焦点、二重
焦点と焦点位置が定まっている。またレンズの度数が場
所により連続的に異なっている累進多焦点レンズにして
もレンズの所定位置に関しては全（前記単焦点レンズの
域を出ない。Conventionally, the purpose of wearing eyeglasses has been to correct refractive power for myopia, hyperopia, presbyopia, etc., apart from fashion eyeglasses such as sunglasses used for special purposes. However, these lenses have fixed focus positions such as single focus and double focus. Furthermore, even with a progressive multifocal lens in which the dioptric power of the lens varies continuously depending on the location, it does not go beyond the scope of the monofocal lens (above-mentioned single focus lens) with respect to a given position of the lens.
一般に人間の眼は年令の増加と共に調節力が減退し固定

替える必要がある。Generally, as the human eye grows older, its accommodative power decreases and the focus becomes fixed, making it difficult to observe distant and near objects with good focus. In particular, when the crystalline lens is removed due to cataract, it becomes essentially a single-point lens, so it is impossible to focus on both far and near objects with normal eyeglass correction. On the other hand, even in the case of correction using progressive multifocal lenses, it is impossible to adjust distance by fixing the line of sight because the focus of the eyeglass lens is partially changed, and it is not possible to adjust distance by fixing the line of sight. Inconveniences such as image distortion occur. In the case of eyes with accommodative power, it is possible to observe both far and near objects due to the accommodative power, but even in young people, if the degree of myopia increases with age, it is necessary to adjust the diopter of the eye. Even if you wear glasses that are made by hand, you will need to change them every time you wear them.
本発明の目的は斯かる従来例の欠点を解決する自動焦点
