Eyesight detector

Abstract

The invention relates to an eyesight detector, and comprises an eyesight test device connected with a test head hoop and a signal transmitting device; the test head hoop comprises a spectacle frame, and a distance-measuring sensor transmitting module arranged on the spectacle frame and eyeglasses rotationally connected with the spectacle frame; the signal transmitting device includes a key moduleand a signal transmitting module electrically connected with a first microcontroller; and the eyesight test device includes a magnetic levitation base and an optotype box levitated above the magneticlevitation base through magnetic force; and the optotype box includes a second microcontroller arranged in the box, a distance-measuring sensor receiving module electrically connected with the secondmicrocontroller, a signal receiving module, an LED indicator set and a data transmission module. The eyesight detector provided by the invention can improve the efficiency of eyesight detection, reduce the workload of medical staff, and meet the requirements of actual application .

Description

technical field [0001] The invention relates to the technical field of vision testing equipment, in particular to a vision testing instrument. Background technique [0002] Vision is the ability of the retina to distinguish images. The quality of vision is determined by the ability of the retina to distinguish images. However, when the refractive media of the eye (such as cornea, lens, vitreous body, etc.) Eyes with a well-functioning retina can still lose vision. In order to correct and treat the patient's vision in a timely and effective manner, it is necessary to test the patient's vision, so the application of the eye chart was born. [0003] The eye chart mainly checks the central vision, that is, checks the central visual acuity in the macular area of ​​the retina, so that the preliminary situation of visual function can be learned simply and quickly, which is of great significance for the clinical diagnosis and treatment of eye diseases. The light box vision tester...

Problems solved by technology

The light box vision tester is used to measure the visual acuity chart. The LED vision tester is a new type of light box based on the principles of energy saving, low carbon, green environmental protection, and accurate detection. However, the light box vision tester still needs manual guidance when performing vision testing. Optotype

However, there is currently a shortage of medical staff, and the use of traditional light box vision testers not only requires a lot of manpower, but also the speed of such vision tests is slow
