All Children and
Adults Need These Visual Skills.
Not All Of Us Have Them
Many different visual skills are involved in our
learning – we must learn to understand what’s going on around us in
order to understand where we fit into things. Understanding and
perception are the keys, and vision plays a major part in clear
understanding and accurate perception.
We must first learn to read so that, later, we can
read to learn. Similarly, the visual skills listed below are needed if
youngsters and adults are to succeed in school and in life. We
specialize in the treatment and enhancement of these vision skills. For
further information please visit www.acbo.org.au

Clearness of vision (acuity):
The ability to see clearly near/far. Clarity at distance is about the
only skill that the usual (Snellen) eye chart examination tests and
tells whether you have 20/20 acuity or you don’t. Generally, people who
have poor distance acuity are nearsighted- that is, do well at reading,
less well at sports. The farsighted person tends to have more
difficulty reading but often does better at sports than the nearsighted
person.
Eye movement skills (fixation ability):
The ability to point the eyes accurately at an object and to keep the
eyes on target whether the object is moving or stationary. Without
these skills: you can’t clearly follow a moving object, such as a
ball in flight; You can’t move your eyes smoothly across a line of text
on a page; You can’t shift the eyes from a close object to a far one,
such as from a notebook to a chalkboard in class.
Eye focusing skills (accommodation):
The ability to adjust the focus of the eyes at the distance from the
object varies. Copying from the board requires constant shifting of
focus from far to near and back again. High level automatic reading for
meaning requires the ability for efficient, minimum demand maintenance
of focus. Most people are capable of a large amount of change of focus,
but fine, accurate control breaks down more easily under stress.
Excellent eye focusing is a skill common to superior athletes.
Eye aiming skills (converging and
diverging):
The ability to turn the eyes inward or outward in looking from objects
close up to objects far away. These skills must be closely coordinated
with eye focusing skills. Inadequacies in these areas seriously hamper
reading ability and athletic performance.
Eye teaming skills (binocular fusion):
The ability to coordinate and align the eyes precisely so that the
brain can fuse the input it receives from each eye.
Even slight misalignment can cause
double vision which in turn the brain may try to eliminate by
suppressing the use of one eye. The brain will react in a disturbed and
defensive manner to confusing signals from the eyes.
Eye-hand coordination:
The ability of the vision system (eye-brain communication) to
coordinate the information received through the eyes in order to
monitor and direct the hands. This skill is important for learning to
write (poor handwriting is often related to poor eye-hand
coordination). It is essential to good performance in most sports.
Visual form perception:
The ability to organise images on the printed page into letters/words.
It is an important skill used in learning to read and is developed
through both experience and practise. It can be taught or improved.
