The application discloses a wireless intelligent iris system, which comprises a controller and an electronic corneal contact lens located on the visual axis, and the controller is wirelessly connected with the electronic corneal contact lens. The controller comprises a light intensity sensor, a microprocessor and a wireless energy emission module. The electronic corneal contact lens comprises a wireless energy receiving module, a ring-shaped transparency adjustable diaphragm and a corneal contact lens front base and back base for encapsulating the wireless energy receiving module and the transparency adjustable diaphragm. The light intensity sensor on the controller converts the environmental light intensity into an electric signal and transmits the electric signal to the microprocessor. The microprocessor controls the electric energy to act on the specific diaphragm through the wireless energy emission module and the wireless energy receiving module on the electronic corneal contact lens, thereby independently controlling the visible light transmittance of each layer of diaphragm. When the transparency of the diaphragm gradually changes and expands from the inner circle to the outer circle, the light entering the eye can be adjusted, thereby improving the vision and visual comfort.

The application discloses a kind of corrective lens design equipment, storage medium and lens, it is related to medical equipment field, for solving the problem of existing refractive correction improves visual acuity or the effect of improving visual quality is poor.Refractive lens design equipment includes acquisition device, selection device and design device, acquisition device obtains the central refractive power of target individual eyeball, selection device finds out target refractive topography from refractive topography group, central refractive power is in the central refractive power range corresponding to target refractive topography, and refractive topography describes the retinal refractive power distribution of eyeball with corresponding central refractive power in preset field angle;Design device obtains refractive power distribution correction scheme in conjunction with target refractive topography, to obtain the corrective lens for target individual.The present application combines the peripheral defocus characteristics of human eye retina to design semi-personalized lens for individual, to achieve the purpose of improving visual acuity, improving myopia prevention and control effect or improving peripheral visual quality.
