Description

Technical Field

[0001] The utility model belongs to the technical field of retinoscopes, and in particular relates to a novel lamp changing mechanism for retinoscopes. Background Art

[0002] The retinoscope uses its lighting system to illuminate the inside of the eyeball. The light is reflected back from the retina. These reflected lights change after passing through the refractive components of the eyeball. The refractive state of the eyeball can be determined by examining the changes in the reflected light.

[0003] The lamp changing structure of the retinoscope currently on the market is not user-friendly. When changing the lamp, the user needs to look at the lamp holder, find the alignment port and insert the lamp holder, which is inconvenient to operate. Moreover, the alignment port of the lamp holder is often an internal structure. When looking at the alignment port, the light is dim, which provides a bad experience. Utility Model Content
