Abstract

The invention discloses a pair of glasses, which comprises a glasses framework, wherein an infrared distance measurer and a sounder are arranged on the glasses frame; the infrared distance measurer is used for measuring a distance from the glasses frame to a read object and is electrically connected with the sounder; and when the distance is smaller than or equal to a set value, the sounder sends a sound. The sounder can send the sound in a near-sight environment, so that a user can be reminded to keep a distance from eyes to the read object; and an aim of preventing myopia can be fulfilled.

Description

technical field [0001] The invention relates to a kind of glasses, which have the function of preventing myopia. Background technique [0002] Reading in a myopic environment for a long time is the main cause of primary and middle school students' myopia. The measure of treating myopia generally is to allow the patient to wear myopia glasses, and it has a frame, and the frame is provided with eyeglass, and this eyeglass has certain diopter. [0003] However, although lenses with diopters can eliminate the blurred vision environment of myopia, they cannot provide a completely natural vision environment after all. Reading in a myopic environment, the degree of myopia may still worsen. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a kind of glasses capable of preventing myopia, so that primary and middle school students can protect their eyes well before becoming myopic patients. [0005] The glasses of the pre...
