4 Dot Test

You can use the Worth 4 Dot Test to assess visual suppression. By using a red/green glass on your client/patient you can easily determine if there is supresrsion or not. If 4 dots are seen, there is no supression. Anything below 4 dots means, there is either supression of the left or right eye. Anything above means the individual is experiencing double images.

Binocular vision is a fundament of all other visual skills. Being able to test it efficiently is a huge plus.
