AI Technical Summary

Technical Problem

The existing bench-top vision correction device is large in size, high in cost and inconvenient in portability, and cannot effectively use natural light for myopia prevention and control.

Method used

A wearable device is designed, including optical element units, support members, optical power sensors and control modules, and myopia prevention and control is used to use natural light sources to measure the incoming pupil light energy through the optical power sensor and generate control signals to adjust the transmittance of the optical element to avoid excessive light energy from harming the eyes.

Benefits of technology

The use of natural light for myopia prevention and control is achieved, which reduces equipment costs, improves portability and market value, and avoids the damage to the eyes caused by excessive light energy.

Abstract

The embodiment of the invention provides wearable equipment. The wearable device comprises an optical element unit, a supporting piece, an optical power sensor and a control module. The support connects the optical element unit to enable the wearable device to be worn by a user to maintain the optical element unit within the user's field of view. The optical power sensor and the control module are carried by the support member. The optical element unit allows light in a target wave band to pass through and can change self transmittance according to a control signal from the control module. The optical power sensor is arranged on a user-facing side of a corresponding optical element unit. Each optical power sensor obtains the actually measured optical power of the light penetrating through the corresponding optical element unit in the target wave band and transmits the actually measured optical power to the corresponding control module. A single control module calculates entrance pupil light energy from measured light power from a corresponding light power sensor within a target time period, and generates a control signal from the entrance pupil light energy.
