Description

Technical Field

[0001] The utility model relates to the technical field, in particular to an ophthalmic trial frame with a headband type elastic band. Background Technique

[0002] When myopic people go to the hospital for vision examination, the doctor will wear the ophthalmic trial frame for the people. The trial frame ensures that patients or customers can try different styles, sizes and types of medical glasses as comfortably as possible.

[0003] However, the current ophthalmic trial frames used in hospitals have the problem of easy slipping during wearing. In order to fix the trial frame, medical staff can only use tape to stick it on the patient's forehead, which is not only unsightly, but also causes pain and inconvenience. It is necessary to redesign an ophthalmic trial frame so that it can better stay on the patient's nose bridge, thereby improving comfort and stability and reducing inconvenience to patients. Therefore, the technical personnel in this field provide an ophthalmic trial frame with a headband type elastic band to solve the problems raised in the above background technique.
