Description

Technical Field

[0001] The present application relates to a contact lens removing device, belonging to the technical field of contact lenses. Background Art

[0002] Contact lenses, also called contact lenses or contact glasses, refer to lenses that are worn on the cornea of ​​the eyeball to correct vision or protect the eyes. During the processing of contact lenses, the lenses need to be placed in an extraction tray for extraction, so that the lenses can fully absorb water and become soft contact lenses that are suitable for human eyes.
