Based on the data reported by National Health Commission of the People's Republic of China, the myopia rate for the children and adolescents is approaching 53.6%, the overall myopia rate is growing in young age, including primary students is 35.6%, middle school student is 71.1%, high school student is 80.5%. As television, computer, tablet, mobile phone invaded people’s life, and the home-based online course, less outdoor activities made the youth’s myopia rate increased rapidly, the myopia control has updated to the national strategy.
To better control adolescent myopia rate, it requires to do dynamic monitoring for the children and adolescent’s eyesight, The eyesight test is the required items as a primary and secondary schools and even kindergarten’s health examination. Create the eyesight health e-record, to achieve eyesight abnormalities and eye lesions monitoring, detection, warning, intervention early.
Along with the medical technology development, eyesight inspection instruments are needed as a portable device, portable eyesight inspection instruments are based on the optical refection principle, it could inspect eyes within seconds, it could measure eye data of myopia, farsightedness, astigmatism, strabismus, anisopia, pupil distance, refraction, axial position, etc. The result is accurate, and it meets the demand for infant eyesight screening and mass screening.
Portable Eyesight Device comprised of lens, optical lens, distant sensor, control board, touch panel , battery, etc.
Optical system combined of lens and optical lens is responsible for radiating, receiving the reflecting signal from eye, obtain picture information from eye; The device should be 1 meter distant from the subject, the distant sensor should ensure the subject is within best testing range.
The control board is the core component which do image processing, functional control, data calculation, to control device light, collect image and process, then use the software to provide the diagnosis result; The touch screen are used for displaying image ,diagnosis result, and it could be operated to control the screening device; Battery power on the device.
To record the testing subject and output the inspection information, it requires the screening device be equipped with WIFI, BT, and connects with the scanner or printer to record the data or to upload the data.
To achieve eyesight screening device portability, rapid diagnosis, the control board must be equipped with strong performance and compact size, it also needs rich data ports, to achieve device control, data collection process and display output etc.
