The MNREAD app is a vision test that uses full sentences. This
reading-acuity test is a digital version of the printed MNREAD ACUITY
CHART, and is suitable for measuring visual reading performance of people
with normal and low vision. MNREAD uses simple text, suitable for testing
adults and children from age eight years and up.

The printed version of MNREAD is available from http://www.precision-vision.com/

The MNREAD app measures four important reading parameters:

READING ACUITY - The smallest print that a person can read without making
significant errors;

CRITICAL PRINT SIZE - The smallest print that a person can read with
maximum speed;

MAXIMUM READING SPEED – A person’s reading speed when reading is not
limited by print size;

READING ACCESSIBILITY INDEX - A single-valued measure that represents a
person’s visual access to commonly encountered printed material.

The MNREAD app has a wide range of applications in testing normal and low
vision. These include:

Prescribing optical corrections for reading or other near tasks.

Prescribing magnifiers or other reading aids in low-vision assessment.

Use in research as an outcome measure or for evaluating visual reading as a
function of vision status or viewing conditions.
