  • the principle of providing appropriate visual acuity to a user by tears can be explained by taking, for example, an aquarium.
  • the aquarium aquarium glass is not optically graded, but fish and objects in the aquarium can be seen clearly even by those with abnormal vision. This is because the refractive index of light in water is different from the refractive index in air, so that even those with abnormal vision can clearly see things in water.

Therefore, in the future, a product development strategy such as purchasing the smart contact lens 100 according to the present embodiment will be possible as if the user selects sunglasses at a general merchandise store.
  • the lens 100 for a smart contact lens provides an appropriate visual acuity to a user depending on the thickness of the retained tear fluid, and therefore, the lens itself corrects the shape of the cornea. It is not necessary to have an optical function, and has a feature that a plano lens can be used.
