Using precise screen calibration and standardized eye charts, combined with AI analysis algorithms, we provide online myopia and astigmatism testing. No appointment needed.

Combining optical principles with artificial intelligence for a trustworthy online vision testing experience
Select your monitor model or manually calibrate to precisely calculate the physical size of each pixel for standardized chart display.
Based on the international Snellen chart standard, testing your visual acuity level by identifying the direction of E optotypes.
Using the astigmatism clock dial test method to detect astigmatism power and axis through differences in line clarity.
Comprehensive analysis of multiple test data points using AI algorithms for cross-validation and reliable diopter estimation.
No need to touch the keyboard from a distance. Simply say 'up/down/left/right' to answer. AI recognizes your voice commands in real-time.
AI uses facial recognition to detect distance and angle in real-time, ensuring standard testing distance before starting.
Point your index finger up/down/left/right to answer. Faster and more intuitive than voice, ideal for distance operation.
Four simple steps to get your vision test report
Select your monitor model or manually enter screen parameters. The system will precisely calculate pixel physical size.
Manually enter or enable camera for AI auto-detection of your distance from the screen with real-time monitoring.
Cover each eye in turn and identify the E-chart direction. Simply say 'up/down/left/right' from a distance.
AI comprehensively analyzes all test data to generate a detailed report including myopia and astigmatism diopters.

The entire process takes only 5 minutes and is completely free. Let AI help you understand your vision.
