Signs of dyslexia can vary from person to person. In children, not all with the condition will display the same reading strengths or weaknesses.
There are tests that we can carry out to assess their stress sensitivity to glare and this is where coloured overlays could be of benefit. Read on to learn more about coloured overlays and how they could help mitigate visual perception issues.
Is dyslexia genetic?
It is estimated that up to 20% of dyslexic people experience visual stress and also the general population in varying degrees.
The following symptoms are common in visual stress:
- Tiring easily when reading
- Letters changing shape or size
- Halos of colour surrounding letters
- Red, sore, watery eyes
- Blurring of print
- Patterns on print
What are coloured overlays?
Is colour the right solution?
- Eye examination
If you're showing signs of visual difficulty when reading, we recommend a full eye examination. If symptoms of eye strain and/or visual stress are not helped by glasses, then an assessment of coloured overlays can be considered.
- Overlay assessment
Our optometrists can carry out an overlay assessment and may suggest that you try an overlay when reading for a few weeks, noting any improvements.
- Colorimetry assessment
The colorimetry assessment may result in precision tinted glasses being prescribed to the you. The colour will be more specific to each individual's needs. This is more precise than the overlay assessment and very often produces a different colour to the overlays. Using coloured lenses means any benefit is gained looking at screens and are therefore more convenient and more practical than overlays.
