Welcome to the MNREAD Acuity Chart web site: Your source for MNREAD information and documentation.
The MNREAD Acuity Charts are continuous text reading acuity charts for normal and low vision.
The charts are used to assess how reading performance depends on print size. Three measures of reading performance are easily obtained: Reading acuity the smallest print that can just be read; Maximum reading speed the reading speed when performance is not limited by print size; and Critical print size the smallest print that supports the maximum reading speed.
The MNREAD Acuity Charts have a wide range of applications in testing normal and low vision: prescribing optical corrections for reading, or other near tasks in the eye clinic, in low vision assessment, prescribing magnifiers or other reading aids, applications in pediatrics and special education, and research.
The MNREAD Acuity Charts were developed at the Minnesota Laboratory for Low-Vision Research, University of Minnesota, by:
The English versions of the MNREAD Acuity Charts are distributed exclusively by Precision Vision Inc.
