Description

Technical Field

[0001] The invention relates to the technical field of spectacles frames, and in particular to a spectacles frame with health-care functions and a preparation method thereof. Background Art

[0002] Glasses are artificial devices made of transparent media and worn on the eyes. Their main uses include: correcting refractive errors and strabismus, improving vision; protecting the eyeballs from strong radiation or irritating substances; treating eye diseases, such as local medication; and beauty.

[0003] With the development of science and technology, electronic products have developed rapidly, and electronic products are closely related to people's lives. However, the use of electronic products does have some potential disadvantages. For example, long-term use of electronic products, such as mobile phones, computers, tablets, etc., may cause vision problems, including myopia, astigmatism, dry eyes, conjunctivitis, etc., especially in children and adolescents. Excessive use of electronic products may increase the risk of myopia. At present, myopia in adolescents increases with age. Statistics show that they are basically normal people at school age, but as they age, the incidence of myopia reaches about 50% by the time they graduate from elementary school, and as high as 60%-70% by the time they graduate from junior high school. When you go to college, after the college entrance examination, the burden on your eyes may be even more serious, so by the time of the college entrance examination, the number of people with myopia in almost every class is about 90%, which is very shocking.

[0004] Existing glasses materials are generally resin, PC, stainless steel, plastic steel, tortoise shell, carbon fiber, titanium alloy and other materials. However, the existing materials only play a role of fixing the frame and do not have health care effects.

[0005] In view of this, the present invention is proposed. Summary of the invention
