This Heidi occluder is multifunctional. It is used for Cover/Uncover Tests with children.

An occluder is one of the most important tools to detect phorias and tropias. But it can also be used for monocular measurements. The Heidi face is a fixation object and attracts children with a smile, making them more cooperative for the exam. With ojects for testing (animals) and grating for other tests. Handle with printing for pupil size and corneal diameter measurement.
