Colorimetry is used to explore colour to find the optimal tint which provides relief of visual stress.
Joanna Williams is our Senior Optometrist and an expert in colorimetry and visual stress. She has many years’ experience using a colorimeter and regularly visits children in schools to screen for the condition.
We have two tests available.
The first is an assessment using coloured overlays, which is usually carried out on children as a screening test. This can be done by Joanna at Sudbury, Halstead or Haverhill and costs £20 or free when booked with an eye test.
The second uses the Intuitive Colorimeter and provides a specific tint for spectacles if required. This can only be done at the Sudbury practice. The cost for this is £50. Should you require tinted spectacles, you will require an up-to-date eye examination prescription.
The cost of single vision Precision Tinted lenses is £189, less the value of any voucher that you are entitled to, plus a frame.
Watch Optometrist Joanna Williams explain the Science of Colorimetry below. Joanna is an expert in visual stress and offers coloured overlay assessments at Sudbury (Suffolk), Halstead (Essex) and Haverhill (Suffolk); and colorimetry only at the Sudbury practice of Wardale Williams, the only opticians in the local area who offers this – call to make an appointment.
All or some of the following symptoms may be present:
Signs to look out for that may indicate visual stress:
Some people may have all these symptoms but often people only suffer with one or two. It’s also harder for children to describe their symptoms or for them to know that what they’re seeing isn’t normal.
No. Dyslexia is a specific learning difficulty which causes the person with the condition to have problems with reading, writing, spelling as well as other things. People with dyslexia often suffer from visual stress and can benefit from overlays or tinted lenses. However, you can have visual stress but not be dyslexic.
We can diagnose and treat visual stress but not dyslexia. If a patient is diagnosed with visual stress and is struggling in other areas than just reading, we would advise a referral to an Educational Psychologist, as they are the only ones who can diagnose dyslexia.
The degree of improvement for each person differs. Some people experience improvements in reading age of one to two years very quickly. In others, the lenses may make it easier to read, but the improvement may be less dramatic because of other difficulties.
We have had some great success stories. You can read the story of Ethan here.
