Free visual assessments

The Dyslexia Research Trust (DRT) was set up to investigate visual causes of reading difficulties and to develop treatments to overcome these. We carry out research studies as well as providing specialised visual assessments and measurements of reading and spelling to compare with general ability, in order to evaluate whether literacy skills are lower than they should be.  But please note that we are not authorised to diagnose 'dyslexia'.

Research Studies

Children between the ages of 7-11 years are invited to take part in our research studies in our Reading Clinic.

Visual Investigation

We test near and distance vision. If reduced, we try to improve the responses through blue and yellow lenses. We assess binocular vision, how well the two eyes work together, particularly in the reading position. This is important to ensure that the child never sees double and the words stay still and clear.

We test 3D vision, as another indicator of how well the eyes work together and the way the brain is processing the visual information.

We use the Ishihara test of colour vision to identify colour blindness and low contrast sensitivity.

Eye movement control is assessed from observation and also using an eye tracker. The fixation, pursuit and saccadic control systems all affect the accuracy of tracking across the page which is vital to determining the order of letters in a word.

Our main research studies the way in which our special blue and yellow glasses can help to relieve visual symptoms and influence the processing of information in the brain.

Recommendations

Finally, we discuss all the results with the parents and children, suggesting ways to improve each individual child’s particular problems.

Treatment can be with blue or yellow glasses. Also we often suggest the value of taking omega 3 fish oil supplements to help visual concentration and immediate auditory recall. We have also found that we may be able to help improve a child’s abilities in tests of similarities and matrices. We offer advice as to how parents can work with their child at home. We follow up most children for at least 6 months, but if necessary we continue to monitor the child’s progress over a longer period of time.

A full report of all findings is sent to the parents for them to show to school if they wish.

We would like to emphasis that all the results we obtain remain entirely confidential and nothing we may publish or talk about could ever be identified with individuals.

Referral can be made by parents direct to the clinic in Reading, phone: 0118 9585950, or via email:drtorthoptics@yahoo.co.uk.

Cancellations
