Follow all calibration instructions carefully. Many apps require measuring your screen or setting viewing distances. Accurate calibration directly impacts result reliability, so invest time in proper setup before testing.
📊 Understanding Your Vision Test Results
Interpreting app-generated results requires understanding basic vision metrics and terminology. This knowledge empowers informed decisions about when professional care becomes necessary.
Visual acuity measurements typically appear as fractions like 20/20 or 6/6 in metric systems. The first number represents your testing distance, while the second indicates the distance at which people with normal vision read the same line. Therefore, 20/40 vision means you read at 20 feet what others read at 40 feet.
Color vision tests classify deficiencies by type—protanopia (red-blind), deuteranopia (green-blind), and tritanopia (blue-blind). Understanding your specific deficiency type helps adapt to daily challenges and informs professional discussions.
Astigmatism results may indicate axis and degree measurements. These numbers describe irregular corneal curvature’s orientation and severity, guiding corrective lens prescriptions if professional examination confirms app findings.
