Description

Technical Field

[0001] This utility model relates to the field of ophthalmic examination tools, and in particular to an ophthalmic eyeglass frame that is easy to adjust and fix. Background Technology

[0002] Most patients undergoing visual field and electrophysiological examinations at hospital ophthalmology clinics are not properly examined. During the examination, a more formal method involves using a spoon-shaped tool to cover the eye being examined. An informal method involves using books, cardboard, or even the examinee's own hand to cover the eye. Using the examinee's own hand to cover the eye makes it easy to cheat, causing the examination results to be inconsistent with the true visual acuity of the eye.

[0003] Based on the above, currently, during ophthalmological examinations, eyeglass frames are usually only used to load polished lenses so that the comfort and dizziness of wearing them can be assessed based on the loaded lenses. Since eyeglass frames do not have the function of occluding the eyes to assist in vision testing, they have functional deficiencies. Furthermore, the use of a spoon-shaped tool to cover the eye not being examined poses a risk of cross-infection of infectious eye diseases as the spoon-shaped tool comes into direct contact with the user's eyes.

[0004] To address this, an ophthalmic eyeglass frame that is easy to adjust and fix is ​​proposed, which has the advantages of easy switching of eyes for examination and quick removal and placement of lenses, thereby solving the problems mentioned in the background art. Utility Model Content
