#BeFirst Fusion


We have two eyes, the retina of each eye forming an image of its own. When we look at an object, we do not see it double because our brain processes the two images and fuses them into one. Fusion is possible only if the two images are almost similar in size and clarity. Our brain cannot fuse two considerably different images. The images on the two retina will be different if the visual status of the two eyes is different. If one eye is weaker or crossed or cannot cross properly. Dissimilar images confuse the brain. The brain, therefore, concentrates only on the BEST image and ignores the other. This is called suppression.

The suppressed eye can work quite well on its own and most people will not ever notice that they have a suppression issue. Both eyes will be open, healthy and look relatively normal during normal activities. This is why it is so important to test and train. People with suppression can have difficulty locating the exact distance of objects in relation to themselves.

This therefore affects depth perception, timing, reactions, speed and accuracy for an athlete. The athlete may feel they have to work so much harder at their skills compared to team mates or other competitors. Particularly in sports that involve a ball, object or person coming towards them.

Its a lot! considering the eyes are so important. If you want to #BeFirst then Fusion is one of the most important features to be using. Fusion will allow you to check if you possibly have a suppression. You can then train your eyes to work together more effectively and develop more strength and endurance in your eye muscles.

Take a look at the diagram below. Then open up Fusion, have a go and check which diagram fits with you.


1- X with the bead in the middle. You should see two strings entering the bead and two exiting the bead

This is the ideal. You want a PERFECT X with the bead in the centre.

- If you have an X BEORE the bead you likely are perceiving things to be closer than they are.
- If you have an X AFTER the bead you are likely perceiving things to be further away than they are.

This affects your depth perception! Think about how this can hinder your performance in your sport!

2- I straight line one string with the bead in the centre.

This indicates a FULL suppression. One of your eyes may not be converging AND/OR the brain can have suppressed the information coming in from that eye.

Common complaints of people with suppression are,

  • trouble catching balls and other objects thrown through the air
  • avoidance of tasks that require depth perception (games involving smaller balls traveling through the air, handicrafts, and/or hand-eye coordination, etc.)
  • poor posture while doing activities requiring near vision
  • one shoulder noticably higher
  • frequent head tilt
  • problems with motion sickness and/or vertigo
  • frequent mishaps due to misjudgment of physical distances (particularly within twenty feet of the person’s body), such as:
  • trips and stumbles on uneven surfaces, stairs, and curbs, etc.
  • frequent spilling or knocking over of objects
  • bumping into doors, furniture and other stationary objects
  • sports and/or car parking accident avoidance of eye contact

3- An incomplete X with one or more strings faded or not visible.

- It is likely that one of your eyes is partially suppressed and is weaker than the other eye. 
- This issue can switch from eye to eye.
- You may notice one or more of the issues from the bullet points above.

To summarise

  • You need both eyes working together perfectly.
  • Many people have a partial or full suppression and this causes a multitude of issues you may not have been aware of until now.
  • Suppression will hinder your performance in your sport.
  • Even if you do not have suppression, the eyes and brain can still reap massive benefits from training the eyes to work together.
