Marsden Ball

Marsden Ball is a vision therapy tool that expands your vision therapy into new dimensions. 

What is a Marsden Ball?

The typical Marsden ball has numbers or letters printed over its surface. It has a string attachment point, and a good length of string, roughly 5 feet, attached to it.Our AmblyoPlay Marsden Ball has letters printed on a red and blue background so that it can also be used binocularly.

Exercises can be performed with an eye patch over the stronger eye or with red and green glasses. If we use it with a patch we improve eye movement, tracking, and depth perception, while the use of filter glasses also helps improve binocularity. With the filter glasses, we split the image each eye receives so we force our brains to start using both eyes simultaneously.

Benefits of Marsden Ball Activities

Marsden Ball exercises might not look very complex and advanced, but this tool offers big benefits to individuals.

Strengthening Eye Muscles

Vision therapy with the Marsden Ball involves performing various eye exercises, which can contribute to the strengthening of the eye muscles. This is particularly beneficial for individuals with conditions like convergence insufficiency.

Increased Range of Motion

Following the Marsden Ball’s movements with your eyes encourages a broader range of motion. This can be particularly beneficial for individuals experiencing stiffness or discomfort in the eye muscles.

Convergence Training

Convergence refers to the ability of the eyes to work together when focusing on a near object. Exercises challenge the ability to converge with eyes and maintain focus.

For Whom is Marsden Ball Suitable?

It is suitable for patients who have problems with binocular vision and conditions such as Amblyopia, Strabismus, and other vision problems. Everyone can use it, children and as well as adults.

Marsden Ball Activities

  • Attach the Marsden Ball to the ceiling or have someone hold the rope in the air so the ball is swinging in the height of the patient’s eyes.
  • Put on AmblyoPlay Glasses (red and green glasses) or other anaglyph glasses.
  • Set the therapy ball in motion.
  • Have an individual call out a letter they are about to press on the ball and then touch that same letter to push the ball away. Repeat for 1-2 minutes. If the swinging gets too fast, stop the ball and restart. You do not need to restart the time!
