Visual Stress describes a number of symptoms that make reading and sometimes writing difficult, slow and often unpleasant especially for more than 10 minutes at a time.

Symptoms of Visual Stress:

·         Blurring of print.

·         ‘Squashed up’ print.

·         Movement of print – jumping, swapping, wiggling or vibration of letters.

·         Letters muddling or words ‘falling off the page’.

·         Letters changing or doubling.

·         Letters fading or becoming darker.

·         Patterns appearing in the print.

·         Illusions of colour – blobs of colour moving on the page.

·         Nausea, discomfort or even pain caused by glare from the page.

·         Rivers of light snaking through the text (often described as waterfalls).

·         Headaches, tired or sore eyes.

 

 Signs when reading:

·         Rubbing eyes.

·         Excessive blinking or looking away from the page.

·         Tiring quickly.  Concentration may be poor and attention span may be short.

·         Poor assimilation of reading text.

·         Losing place easily.

·         Poor spelling.

·         Misreading words.

·         Speed or rate of reading is slower than expected for intelligence level.

PLEASE NOTE:

1.  Letter reversal and inversion are associated with dyslexia, and are not helped by colour.

2.  Please ensure you have a standard eye test to check eye health.

3.  An orthoptist will investigate binocular vision anomalies, diagnose and treat strabismus (squint), amblyopia (lazy eye) and ocular motility (eye movement). These conditions may be responsible for blurring and doubling, especially if they do not ease with the use of colour.
