Melina Joy Opticians Ltd

Melina Joy Opticians Ltd was established in February 1992 and provides all aspects of professional and friendly eye care, contact lenses and precision tinted lenses

We realise the importance of having good vision especially in the young; and the installation of the Intuitive Colorimeter in 2009 has enabled the practice Optometrists to fully investigate Visual Stress. This stress is known to cause visual perceptual problems in both adults and children and subsequently interfere with reading.

The symptoms can occur despite normal vision.

Visual stress is sensitivity to visual patterns, particularly stripes and flickering lights. About 40% of migraine attacks may be visually induced by flickering light, striped patterns or intense reading tasks.

One current scientific explanation is that the perceptual problems are due to a hyper-activation of the Visual Cortex of the brain. Functional MRI scanning has shown that this activity is reduced by the application of Precise Individual Colour.

The Process
1)          The Eye Examination
We recommend that every child or adult who displays the symptoms of Visual Stress, have a full vision examination to make sure there is no defect of sight left uncorrected and those candidates suitable for treatment using colour, are put forward for Coloured Overlays assessment and Colorimetry.
2)          Overlay Assessment
An assessment with Coloured Overlays will be carried out by one of our optometrists. It may be suggested that the Overlay is used for a few weeks to record any improvements. If the improvement is immediate the Optometrist may suggest moving directly to testing with the Intuitive Colorimeter.
3)          The Colorimeter
This may result in the prescribing of spectacles with Precision Tinted Lenses which are much more precise than the overlay and are more convenient to use in everyday life for the student. Precision tints can also be helpful to the adult migraine sufferer.

Wilson, Wilson & Hancock Opticians

Wilson Wilson & Hancock has been established since 1948 and has branches in Hastings, Lewes, Rye and Tenterden. We purchased a Colorimeter when it was first released onto the market and have always had a particular interest in testing adults and children with learning difficulties since our founder Frank Wilson specialised in orthoptics.

The Colorimeter changes the hue, saturation and brightness of colour on reading text and gives a final colour precise to an individuals needs. The colour choice comes from over 10,000 colour combinations and is most effective when incorporated into a pair of spectacles.

Over the years we have had many successes with patients, who have benefited from the use of colour overlays and precision tinted lenses. Reports range from improving reading ability and increased concentration span, to migraine relief.

Please advise our staff if you are booking for any of these services, which are usually carried out of our Hastings and Lewes practices by Paul McDonald, Elizabeth Christie, Georgina Hacker, or Dr Rebecca Daniels-McDonald.

Please telephone Hastings on 01424 421717 or Lewes on 01273 472360 to arrange an appointment.

Visual Stress

Visual stress is not a symptom of dyslexia but 50% of those who have visual stress also happen to be dyslexic.

According to the British Dyslexia Association (

Visual stress is not a symptom of dyslexia but 50% of those who have visual stress also happen to be dyslexic.

People with visual stress may experience one or several of the following:

  • Blurred letters or words which go out of focus
  • Letters which move or present with back to front appearance or shimmering or shaking
  • Headaches from reading
  • Words or letters which break into two and appear as double
  • Find it easier to read large, widely spaced print, than small and crowded
  • Difficulty with tracking across the page
  • Upset by glare on the page or oversensitive to bright lights

In some cases any of these symptoms can significantly affect reading ability. It can also make reading very tiring. Of course a child will not necessarily recognise what they see as a problem, as this is how they always see text.
