Read Ez - Colorimetry / Visual Stress Testing

Do words appear to move, wobble or flicker when you read for any length of time? Do your eyes get tired or do you get headaches when reading? You might be one of the 20% of the population who suffers from a condition known as Visual Stress.

Visual Stress is thought to be caused by hyperactivity of certain groups of cells in the brain. 

For reasons that are still not well understood, these disturbing effects can often be reduced or even eliminated by placing a sheet of coloured plastic (an overlay) over the page or using coloured lenses. Interestingly, the colour required to achieve this varies from one person to another and the colour can be different for overlays and lenses.

For some the benefits may be slight but for others the effects can be dramatic, significantly increasing reading speed and fluency and reducing headaches and eyestrain.

A school teacher in New Zealand  (Olive Meares) and and educational psychologist in the US (Helen Irlen) were among the first to report this phenomenon so the condition has become known as Meares-Irlen syndrome or simply Visual Stress.

The ReadEZ system was developed at City University London by a team led by optometrist and visual scientist, Professor David Thomson. The system is used by over 400 Opticians and in many hospitals and schools and our coloured overlays, coloured lenses and screen tinting software are now used by 1000s of people around the world.

We can undertake visual stress / colorimetry testing for a fee of £54.

This includes the testing and a sample of the preferred overlay.

Further overlays and tinted spectacles can be supplied as necessary.
