“I use the Frisby Stereotest as the first part of every examination of a very young patient after obtaining History and Symptoms from the parent. Quick and easy for both young patient and Optometrist, it brings a smile to child and parent. Watching the child’s preferential eye gaze is often enough for a response.”

“Possibly the most useful subjective test of stereopsis for young children is the Frisby Stereotest, as it provides real depth in the display and does not require the child to wear dissociating spectacles.”  

“A very useful screening method.. easy to explain to the patient in terms of what they are supposed to be seeing due to its size and simplicity …the screener is a useful size, handy to have a portable test for stereopsis at an inexpensive price. The test easily fits into my equipment bag so is a very useful addition.”

"The FD2 is a great distance stereo test and one that I enjoy teaching our students about."
