Go4health nurses provide a few different Vision Tests to suit your needs as follows.

Visual acuity test

A visual acuity test is a way to detect vision problems and is used frequently for screening.

A standardized Snelling chart is used for visual acuity testing to determine the smallest letters an employee can read on the chart held 3 meters away.

 

Test for Colour Blindness

The Ishihara colour plate / colour perception test is a screening tool for colour vision deficiencies and is by far the most well- known colour vision deficiency test used all around the world.
