Description

Technical Field

[0001] The present invention relates to the technical field of myopia correction, and in particular to electronic myopia glasses and a method of using the same. Background Art

[0002] According to statistics from the World Health Organization (WHO), the prevalence of myopia is increasing worldwide, and the number of myopic people in the world has exceeded 2 billion. In terms of geographical distribution, the myopia rate is highest in Asia, with China and Singapore both exceeding 80%. In addition, the myopia rate in European and American countries is also gradually increasing, especially among young people. Statistics show that China is not only the world's largest myopic country, with nearly 700 million myopic people, but also the country with the highest myopia incidence rate, with the incidence rate of myopia among urban teenagers reaching 67%.

[0003] At present, the mainstream method is to correct daily vision by wearing myopia glasses. Myopia glasses (English: Myopia glasses) are glasses designed to correct vision so that people can see distant objects clearly. The purpose is to enable the ciliary muscles of the eyeball to maintain a certain degree of adjustment. Myopia glasses are concave lenses. The refractive power of the lens is generally expressed in degrees. One diopter (dioptre) is equivalent to 100 degrees as mentioned by ordinary people or optical shops. However, if the degree of the glasses is inaccurate, whether it is overcorrected or undercorrected, it will cause blurred vision, force the eyes to over-adjust, and thus accelerate the development of myopia. In addition, if the glasses are of poor quality, such as lens wear, or incorrect wearing method, it will also affect the correction effect of vision. The more serious the vision problem, the deeper the lens degree required and the thicker the lens will be. Moreover, the degree of traditional glass or resin myopia glasses is fixed after fitting, and cannot be applied to different usage scenarios. For example, the refractive adjustment requirements for reading, looking at computers, watching TV, viewing blackboards, and projecting PPT are not consistent. The fixed degree of glasses will inevitably make it difficult for users to see the target clearly in at least one scenario, resulting in excessive squinting and tightening of the lens. In the long run, this will inevitably lead to an increase in myopia and may also cause other eye diseases.

[0004] In addition, before the age of 30, the degree of glasses worn by myopic people, especially those in developing adolescents, will gradually increase, and they will basically need to replace their glasses with higher degrees every 1-2 years. After the age of 30, as people age, the eye-related muscles relax, the degree of myopia will gradually decrease, and there will also be a need to replace myopic glasses with lower degrees. Wearing glasses with the right degree can not only ensure a clear field of vision, but also be beneficial to the health of the eyes. However, the price of myopic glasses can easily be hundreds or thousands, and they need to be tested and fitted by professional institutions, which is a large time and financial burden for myopic people.

[0005] Therefore, providing electronic myopia glasses with a simple structure and the ability to accurately adjust the diopter according to the user's situation has become a difficult problem that needs to be solved urgently. Summary of the invention

When the user wears electronic myopia glasses, the peripheral vision of each eye is 30 degrees (natural light), the same as the existing resin or glass myopia glasses. The catadioptric optical display lens group 41 and the camera are selected accordingly to ensure that the user obtains the best field of view.
