Vision has three components sending the information to the eye processing of the information by the brain and making sense of the information

80% of information is Vision. Vision is motor occurs in the brain and is intra sensory.

vision therapy is a top down approach where we start from the brain.

In the visual system is of two types the central system and the peripheral system

when the central system is compromised we see behaviours like rocking back and forth while reading , side vision etc . most of our visual testing checks for this central system.

06% of our vision is central vision and 94% of our vision is peripheral vision which goes undetected it is this peripheral vision which manifest as

level one reading difficulties difficulties in sports like catching the ball

level two visual organisation in depth perception

Central visual compromises results in behaviours like difficulty in copying from the board and running into things

it is very important to check in kindergarten . after checking the power the check is carried on focusing skills which Includes the amount of time we focus and the ability to shift the focus from distance to near and Vice versa.

Treatment for this is based on trial and error and tints are used and polarity is also changed.

Fixation is the next skill that is checked this manifests as poor eye contact, lack of focus and difficulty in decoding linger words.

Pursuit or slow tracking is the next skill that is checked. this is the ability to track the object and manifest as bad handwriting and Inability to catch the ball.

Saccadic eye movements which is the ability to converge vision is the next assessment .

The complete assessment takes two sessions of 20 minutes each

vision therapy can work for adults as well.
