The height of color display screen is adjusted, and meets the needs of each height crowd.
Preferably, the control device includes time set.Facilitate carry out timing, judges to mistake.
Operation principle is as follows：
Myopia checks operation principle：
After the vision tester connection power supply, selection option is shown on the colorful display screen, after selecting near-sighted option,
Distance of the ranging camera head to checked people apart from the colorful display screen is detected and is sent to measured distance
The control device, the size that control device controls on colorful display screen " E " according to distance (answer by the distance of usually test myopia
It it is 10 meters, often row's " E " size is fixed on standard visual acuity chart, and such as distance is n meters, then is shown on the colorful display screen
The size of " E " is n/5 times.).When starting to check, the loud speaker starts to put question to, and colorful display screen is shown since maximum " E "
Show, the time set starts timing, and checked people needs before timing stops by the directional pad or to the microphone
Voice says direction and answers, if answered questions, shows smaller " E ", if not answering or answering mistake, the control device control
It makes the colorful display screen and reveals eyesight level.
Colour blindness checks operation principle：
After the vision tester connection power supply, selection option is shown on the colorful display screen, after selecting colour blindness option,
Distance of the ranging camera head to checked people apart from the colorful display screen is detected and is sent to measured distance
The control device, control device controls the size of colorful display screen colouring blind examination altimetric image according to distance, when starting to check,
Colorful display screen starts to show that colour blindness detection image, the loud speaker start to put question to, and the time set starts timing, is examined
People needs before timing stops through the numeric keypad or says the microphone voice content in pattern to answer, institute
It states control device and collects the information answered, after waiting one group of pattern displaying, according to the information answered is collected, be made whether coloured
Blind judgement.
In conclusion by adopting the above-described technical solution, the present invention at least has the advantages that：It is taken the photograph by ranging
It as head confirms the distance between checked people and the colorful display screen, and is resolved, is determined colored by control device
The size of pattern on display screen avoids that the complex operations that plane mirror is reflected are arranged again.Colorful display screen can be shown closely simultaneously
It can also show that colour blindness detection image, energy one-machine-multi-function facilitate carry out eye test depending on table.
