Summary
A new smart visual acuity measurement (VAM) system uses a Raspberry-Pi and touchscreen for precise eye exams. This system simplifies testing for visual acuity, astigmatism, and color blindness.
Area of Science:
- Ophthalmology
- Biomedical Engineering
- Computer Science
Background:
- Traditional visual acuity testing methods can be cumbersome.
- There is a need for more efficient and user-friendly diagnostic tools in eye care.
Purpose of the Study:
- To design and implement a smart visual acuity measurement (VAM) system.
- To evaluate the system's performance in examining visual acuity, astigmatism, and color blindness.
Main Methods:
- A hardware setup comprising a wireless remote controller with a touchscreen and a Raspberry-Pi controlled high-resolution LCD.
- A smart application developed in Visual Studio software for data processing and task execution.
- Automatic adjustment of optotype size based on patient distance.
Main Results:
- The system successfully performed visual acuity, astigmatism, and color blindness examinations.
- Practical evaluation under expert supervision confirmed the system's precision.
- The VAM system offers an easier and more comfortable examination experience.
Conclusions:
- The developed smart VAM system provides a precise and user-friendly solution for eye examinations.
- This technology has the potential to improve the efficiency and comfort of optometric assessments.
