近用眼镜
摘要：
本发明涉及一种光学器件，尤其是一种近用眼镜。现有近视眼镜和近用眼镜不适合眼近视者近用，为了解决这个问题，本发明提出一种近用眼镜，其特征在于子镜光学中心在主镜光学中心下方2mm左右，子镜覆盖的近用区域占镜框内空高度的2/3左右，子镜屈光度绝对值≤主镜屈光度绝对值，子镜与主镜形成的镜片联合区域的总屈光度为0.00D～-4.00D。其有益效果是，解决了现有近视眼镜和近用眼镜不适合眼近视者近用的问题，结构不复杂，制作不困难。
摘要（英）：

The invention relates to an optical device, in particular to short-distance eyeglasses. In order to solve the problem that the conventional myopia eyeglasses and the short-distance eyeglasses are not suitable for shortsighted persons to wear within a short distance, the invention proposes short-distance eyeglasses. The short-distance eyeglasses are characterized in that an optical center of a sub lens is about 2 mm away from the lower part of an optical center of a main lens; a short-distance area covered by the sub lens occupies about 2/3 of empty height of an eyeglass frame; the diopter absolute value of the sub lens is less than or equal to that of the main lens; and the total diopter of a lens joint area formed by the sub lens and the main lens is 0.00D-4.00D. The short-distance eyeglasses have the benefits that the short-distance eyeglasses solve the problem that the conventional myopia eyeglasses and the short-distance eyeglasses are not suitable for the eye shortsighted persons to wear within the short distance, have a complex structure and are easy to manufacture.
