For accurate testing you must print the Visual Acuity Chart, which appears on one side of RPB's Visual Acuity Card.
Do not use screen images to perform the test as they are not to scale.
Visual Acuity Chart
Use this side of RPB's Visual Acuity Card to test your Visual Acuity. If, after following the instructions, you can read the 20/20 line, your vision is normal.
