PA Vision Infant Acuity Flip Test

The PA Vision Infant Acuity Flip Test is a quick and convenient flip chart for testing and quantifying visual acuity. The test is designed to measure the visual acuity of children ages one to three years in age, but it can also be used to test the vision of older children and adults with intellectual impairment. The technique used requires no recognition or communication from the patient, and as a result this test is effect for diagnosing visual impairment in otherwise hard-to-test individuals.

• Designed for testing visual acuity in infants and toddlers
• Can be used to test children and adults with intellectual impairment

About the Testing Method

The PA Vision Infant Acuity Flip Test is a collection of grey pages, each with a "vanishing optotype" made up of black and white outlines. The outlines of these optotypes (images) vary in narrowness, and, as a result, an image will appear invisible to the patient when the lines of an optotype exceed their range of vision. The test exploits our preference for looking at images rather than blank spaces, and this preference for images allows the examiner to quantify the patient's visual acuity simply by noting their eye movements when shown an image. 

The PA Vision Infant Acuity Flip Test

The convenient flip chart design of the PA Vision Infant Acuity Flip Test enables the test to be quickly and easily reset for the next test patient. It also allows the examiner the choice of holding the test pages on their lap or placing the flip chart on a table.
