Dyslexia Vision

Dyslexia vision


At Alfred Jay Opticians we provide a specialist dyslexia vision service – specific visual assessments and corrective lenses that have been clinically proven to help children and adults with dyslexia as well as learning and reading difficulties – including visual stress.

Visual stress is a term used to describe visual discomfort and perceptual distortions in printed text, and is suffered by many people who struggle to read. The condition is estimated to be present in approximately 40% of poor readers and 20% of the general population.

Dyslexia vision tests (also known as ‘school vision tests’ or ‘school vision screening’) are not part of the basic NHS eye examination, which only deals with the health of the eyes and how well each eye can see.

When we read, our dominant eye should take over the job of aiming at the words.  However, if both eyes compete to do the same job, the words and letters may appear to shift out of order, sending confused messages to the brain.  This can cause difficulties in reading and spelling.

If this takes place when a child is learning how to read, the effect on confidence, enjoyment of reading and behaviour can be profound.

Problems often appear as fatigue, headaches, frustration and may even manifest as a lack of attentiveness or poor behaviour in class.

In extreme cases, this can also affect other areas of development.

At Alfred Jay Opticians, with a Diploma in School Vision, Rabiyyah is experienced in specialised visual assessments and corrective coloured lenses and glasses for dyslexia and visual stress (including coloured overlays).

Coloured lenses can reduce binocular problems and improve reading and vision for people with dyslexia, visual stress and associated reading difficulties.

It is important to note that whilst the test is termed a ‘school vision test’ or ‘dyslexia vision test’, the test is applicable to children and adults and relates to dyslexia, visual stress and similar visual difficulties.

If a child or adult complains of at least one of the following, they may benefit from special vision tests:

  • Blurred letters or words which go in and out of focus*
  • Letters which move, shimmer or shake or present back-to-front
  • Headaches or fatigue from reading
  • Words or letters which split into two and appear as double
  • Finds it easier to read large, widely spaced print
  • Difficulty with tracking across the page
  • Upset by glare on the page, whiteboard, computer screen
  • Oversensitivity to bright lights
  • Poor reading ability
  • Poor concentration
(*A child may not necessarily recognise what/how they see as a problem, as this is how they always see text.)

Many of the signs and symptoms associated with learning difficulties, visual stress and dyslexia may be due to a binocular visual problem, which, once corrected, will make a significant, positive difference to their reading and learning.

The benefits may include:

  • Better school performance
  • Improved reading ability and speed
  • Improved arithmetic
  • Increased self-esteem & self-confidence
  • Clearer writing
  • Increased concentration
  • Decreased tiredness and anxiety
  • Reduction of headaches/migraines; and
  • Reduced hyperactivity
