Description

Technical Field

[0001] The present application relates to the technical field of vision screening, and in particular to a vision screening device. Background Art

[0002] Visual acuity refers to the ability of the retina to resolve images. The quality of visual acuity is determined by the ability of the retina to resolve images. However, when the refractive media of the eye (such as the cornea, lens, vitreous body, etc.) become cloudy or there is a refractive error (including myopia, hyperopia, astigmatism, etc.), the vision of the eye will still decline even if the retina functions well. Early children cannot describe their vision well, so they need to use vision screening equipment for testing.

[0003] Traditional vision screening devices are mostly handheld. Although they are easy to operate and carry, they need to be held up by the arms when used. Long-term use requires a lot of physical strength and can easily cause damage to the elbow joints and arm muscles, affecting the health of medical staff. Therefore, a vision screening device that does not cause arm damage is needed.

[0004] The Chinese patent with publication number CN214511124U discloses an eccentric light vision screening device, which has a first limiting column and a second limiting column and a limiting groove that can be detached separately, making it more convenient to carry out.

[0005] However, in the above technical solution, after the first limiting column and the second limiting column are disassembled, the number of components increases, which is not easy to carry and is prone to loss of components. Utility Model Content
