Binocular vision is the ability of both eyes to work together to maintain focus on one point or object at the same time to create a single visual image.
The inability of the eyes to coordinate together in this manner can lead to depth perception problems and difficulties with effectively judging distances.
Binocular vision skills develop in the first few years of life. It is important for parents to ensure that children have an eye examination before starting school to assess their vision, or earlier if recommended by your child health nurse or GP.
A child with binocular vision problems will more than likely experience learning difficulties, which can have a broader impact on their development, confidence and well being.
There are two main causes of binocular vision problems:
- Lazy Eye (amblyopia) – when vision in one eye is weaker than the other resulting in the brain effectively switching off the vision in the ‘lazy’ eye.
- Cross Eye (strabismus) – eyes are pointing in different directions resulting in difficulty to focus on one particular point at the same time.
