Eye alignment, or better alignment of focus between the two eyes, is indispensable both for clear seeing and for seeing the world as three dimensional.

This month’s technique is particularly valuable for anyone with strabismus (squint), amblyopia (lazy eye), diplopia (double vision), and of course everyone else who wants to enjoy the depth of the world. If you currently see your surroundings as flat this may be a valuable step in getting the third dimension into your visual repertoir.

Enjoy the lesson and may your eyesight be boundless.

• Small sticker to mark your target (optional) - cutting out a little square from the sticky part of a post-it works great and it is easy to remove when your practice is finished
