Abstract

The invention relates to application of hyaluronic acid in the preparation of an oral product for preventing and treating myopia. The hyaluronic acid is orally taken for preventing and treating the myopia, which has the following advantages: 1) the hyaluronic acid can get to organs of eyes through oral taking and absorption so as to directly avoid the concentration reduction of the hyaluronic acid in tissues of a short-sighted eye and related pathological changes resulted from the concentration reduction of the hyaluronic acid, thus the biological and mechanical properties of avsclera are restored to prevent and reverse the deformation of an axis oculi so that the diopter reaches the normal level to recover the vision; 2) the hyaluronic acid has the function of protecting mucosal, can effectively protect eye mucosa from being stimulated and injured, alleviate eye fatigue, and further alleviate the weakening vision due to overuse of the eyes and the like; and 3) the hyaluronic acid has good biocompatibility and no side effects for oral taking.

Description

technical field [0001] The invention relates to the application of hyaluronic acid in the preparation of oral products for preventing and treating myopia, and belongs to the technical field of health food and medicine. Background technique [0002] The prevalence of myopia in our country is about 33%, that is to say, about 400 million people are myopic. Among the teenagers in the country, the "spectacles family" of elementary school students accounts for 1 / 3, junior high school students account for 1 / 2, and high school students account for 1 / 3. Accounted for 3 / 4. What is even more concerning is that there are more than 30 million people in China with pathological myopia whose myopia is higher than 600 degrees and accompanied by fundus changes. Such myopia can be complicated by retinal detachment, glaucoma, cataract and other diseases, which seriously threaten people's health. Therefore, it is urgent to prevent and treat myopia. [0003] The current research results show th...
