Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmology, in particular to an optometry instrument with a face bracket. Background Art

[0002] An ophthalmometer is a professional device used to check human vision and eye diseases. It can measure indicators such as eye power, astigmatism, corneal curvature and visual acuity. When using the ophthalmometer, the person being measured needs to keep his or her line of sight in a straight horizontal line with the lens. During long-term measurements, it is often difficult for the person being measured to maintain the same action for a long time, so the person being measured often moves his or her head inadvertently, making it impossible for the line of sight to remain in a straight horizontal line with the lens, affecting the measurement results.
