[0025] Example 1
[0026] like Figure 1A , Figure 1B and figure 2 As shown, the present invention is a contact lens for treating fungal keratitis, which is a curved contact lens as a whole, and the contact lens includes a soft layer, a hard layer, a hollow microcavity, and a micro fluid channel , liquid outlet and other structures (hollow micro-cavities and micro-fluid channels can be set in the soft layer; the hard layer has a certain strength, such as the Young's modulus of 0.1-10GPa level, the soft layer and the hard layer The difference lies in the softness and hardness of the materials used. The hard layer is harder than the soft layer. Correspondingly, the soft layer is also softer than the hard layer. The softness and hardness of the material can be compared according to the degree of local plastic deformation on the surface of the material. , the soft layer can be, for example, a material with a Young's modulus of 0.1-10 MPa).
[0027] The contact lens has a spheri...
