Description

Technical Field

[0001] The utility model relates to the technical field of optometry detection equipment, and more specifically to an optometry trial lens device. Background Art

[0002] Hyperopia, myopia, amblyopia and other eye diseases are common diseases. Currently, the best way is to wear glasses. When fitting glasses, it is necessary to obtain the accurate degree of glasses that need to be configured for myopia through optometry. Optometry is to check the convergence of light after entering the eyeball. It uses the emmetropia state as the standard to measure the degree of convergence difference between the examined eye and the emmetropia. Optometry is one of the most basic, most commonly used but important tasks of optometrists. Optometry glasses are a pair of glasses with interchangeable lenses, generally including an optometry frame and optometry lenses of different degrees. By replacing the optometry lenses in the optometry frame, the degree of glasses to be worn can be determined so that the patient can be fitted with a pair of suitable glasses.

[0003] After searching, the utility model patent with the announcement number CN220001724U discloses an optometry trial lens device, including a first frame and a second frame, an adjusting mirror rod for adjusting the distance between the first frame and the second frame is arranged between the first frame and the second frame, an axle rod is arranged on the adjusting mirror rod, a plurality of rotating seats evenly spaced are sleeved on the axle rod, a clamping assembly is connected to the rotating seat, the clamping assembly is used to clamp the first optometry lens, and a limit assembly is arranged on the adjusting mirror rod to limit the first optometry lens between the first frame and the second frame. When confirming the degree in a small range, by rotating the rotating seat, different first optometry lenses are placed on the first frame or the second frame for degree adjustment, and there is no need to take and place from the placement table, which simplifies the operation steps and effectively improves the optometry efficiency.

[0004] However, the above patent has the following shortcomings: when adjusting the distance between the first frame and the second frame by adjusting the mirror rod, the distance between the first frame and the second frame can only be adjusted to several specific distances, which is not practical; in addition, the first trial lens is clamped by the clamping assembly, but the clamping assembly is located on the outside of the sleeve rod on the adjusting mirror rod. When the adjusting mirror rod adjusts the distance between the first frame and the second frame, the clamping assembly will also be offset, which is not convenient for ensuring that the first trial lens can be rotated to the front of the first frame or the second frame. For this reason, we propose an optometry trial lens device. Utility Model Content
