Check your Dominant Eye
The first thing that should be done is to check which is your dominant eye. The reason for this is that although your dominate eye and hand are USUALLY the same, it is actually not that uncommon for those to be different. This can really affect the quality of the HMT performance.
To find your dominant eye, follow the steps below:
Holding your hands out straight in front of you, connect your index fingers and thumbs, creating a triangle:

Using both eyes, focus through the triangle on a small object on your desk, a mouse or phone for example.
Close your left eye, then open. Close your right eye, then open. When you close one of these eyes, the object appears to jump out of the triangle.
Your dominant eye is the eye where the object does not move outside the triangle when you close your other eye.
