Description

Brock string excercise improve the extraocular muscle ability to converge and control the outward deviation of the eye.

PURPOSE: To develop better coordination between your two eyes when you are looking at objects located at different distances. You will know that you are using both eyes correctly in each exercise when you can look at a small object and see it as one, while
noticing that all other small objects in front of and behind it are double.

Step:
1,Look at the red ball closest to the eye until you see the phenomenon as shown.
2,Look at the yellow ball in the middle of the eye until you see the phenomenon as shown.
3,Look at the green ball farthest from the eye until you see the phenomenon as shown.

Description:
Brock String – used in fixing convergence insufficiency and sports training.
The basic purpose of the Brock String is to develop good binocular functions;  in other words to get both eyes working together well.  This activity teaches convergence – the ability to point both eyes more accurately at a target.
