Description

Technical Field

[0001] This utility model relates to the field of vision correction technology, specifically a device for vision correction. Background Technology

[0002] Due to various factors such as disease, lifestyle, diet, and work environment, more and more people are experiencing vision problems, mostly manifesting as myopia, hyperopia, and astigmatism. Currently, in addition to wearing glasses for optical correction, there are surgical and drug treatments for vision problems, as well as emerging specialized vision correction instruments.

[0003] Most existing vision correction and rehabilitation training equipment is non-adjustable, making it difficult to adapt to people with different eye distances. Existing equipment often uses a series of rehabilitation instruments to correct vision, requiring a complete replacement of the entire system when changing instruments, followed by readjustment, resulting in cumbersome operation and hindering rapid deployment. Therefore, we offer a vision correction device to solve these problems. Utility Model Content
