In the process of implementing the invention, the inventor finds that the prior art has at least the following problems:
contact lenses are worn on the eye and cause some change to the eye. Ophthalmology has only learned that the cornea needs to take up nutrients from the air for normal metabolism, and that once a contact lens is placed in front of the cornea, the cornea is slightly hypoxic because it cannot get enough oxygen from the air. This can lead to a series of pathological changes in the eye, such as mild edema of the corneal epithelium. Contact lenses are prone to water or foreign body contamination that can further damage the wearer's eyes.
