[0002] Ophthalmology is a specialized field of medicine that specializes in the study of various eye diseases and treatments. Ophthalmologists are usually responsible for diagnosing, treating and preventing eye diseases, including myopia, hyperopia, glaucoma, cataracts, keratitis, conjunctivitis, etc. Ophthalmologists are also responsible for performing eye surgeries, such as cataract surgery and corneal transplants. Ophthalmic optometry is an important part of an ophthalmologist's job.

The vision behind each lens is measured and the measurement results are recorded. This is the common structure and use of ophthalmic optometry functional equipment. When using common ophthalmic optometry functional equipment, most of the operations require manual operation, and some equipment is too large, resulting in disadvantages such as inconvenience in use. For this reason, an ophthalmic optometry functional equipment is proposed. Utility Model Content
