Welcome to the official website of Nanjing Tamso Optoelectronics Co., Ltd.
Dark adaptation ability refers to the ability of the human eye to adapt when the environment changes from light to dark. All motor vehicle drivers must have good night vision and quick dark adaptation ability. The quality of drivers' night vision and dark adaptation ability directly affects the safety of the lives of drivers and passengers.
Instrument Features
1. It uses modern components such as LCD display, keyboard, printer, and microcontroller system, automatically controlling the function conversion of the instrument, achieving human-computer interaction, greatly improving the level of automated control of the instrument, and has a sense of the times;
2. It has complete functions for various night vision examinations, with the entire examination process's operating procedures, working status, and the examinee's reaction status and judgment displayed on the LCD screen, and the examination results are automatically printed, making operation simple and convenient;
3. The examiner can directly observe the eye tremor waves of the examinee's eyes at any time through the monitor, making the examination results accurate and objective; convenient and fast;
4. Reasonable structure, easy to use; can be checked in a general examination room without the need for an absolute dark room;
