WHAT IS VISUAL STRESS?

A condition contributing to reading difficulties, eye strain and headaches when reading. It can be responsible for light sensitivity, appearance of patterns in the text and glare effect.

WHAT CAUSES THE VISUAL STRESS?

The hypothesis is that the stress is due to a hyper excitability of the neurons in the visual cortex, an area of the brain at the back of the head, which fire inappropriately. In other words these cells kind of work a bit too fast which causes the disturbances in the text.

IS VISUAL STRESS THE SAME AS DYSLEXIA?

Visual stress can be due to a number of conditions including Dyslexia, but is not the same.

WHAT ARE THE SYMPTOMS OF VISUAL STRESS?

  • glare
  • headaches when reading
  • movement/blurring of print
  • eye ache
  • rapid tiring

WHAT ARE THE SIGNS OF VISUAL STRESS?

  • rubbing eyes
  • increased blink rate
  • poor concentration
  • using finger as marker
  • low self esteem

WHAT CAN HELP WITH VISUAL STRESS?

Scientific research has shown that visual stress from reading can be reduced by colouring the page using spectral  filters. These filters are either placed directly over the page (these are known as coloured overlays) or they are worn in Spectacles (Precision Tints).


HOW CAN I GET COLOURED LENSES?

The colour of the lenses can only be assessed by using The Intuitive Colorimeter, which uses a much larger range of colour combinations than used with the overlay assessment. This therefore gives a much more accurate colour specific to each patient.

WHERE CAN I GET ASSESSED FOR COLOURED LENSES?

All you need to do is to book in for a eye examination with ourselves.  The eye examination is to check for any need for spectacles or eye muscle problems. After the eye examination we can then carry out a test using the Intuitive Colorimeter. The results are normally instant. Then if needed, the coloured lenses can be ordered to suit

CAN YOU HAVE PERFECT EYESIGHT AND STILL EXPERIENCE VISUAL STRESS?

YES, perfect eyesight means you can read all of the letters on the chart without glasses and both of your eyes work together in the way they should. Visual stress can come from a binocular anomaly, but this will be corrected before any colour is used. If Visual Stress is still occurring after all binocular problems have been sorted the cause is likely not to be due to the eyes but the visual cortex part of the brain. Colour is likely to help on these cases.
