Our Reading Guides are similar to Overlays but are A6 sized, with your preferred colour in the middle and darkened areas above and below. This helps you track as you are reading, while the colour helps to minimise the symptoms of Visual Stress.
ReadEZ Clip-Ons are available in 12 colours and two saturations making a choice of 24 shades. Simply attach the clip-ons to your glasses whenever you need them. The lenses are ophthalmic quality and the colours have been carefully selected by Vision Scientists to minimise the symptoms of Visual Stress.
ReadEZ tints are available in 24 shades which can be applied to spectacle lenses. Our network of ReadEZ Test Centres will carefully assess you for signs of Visual Stress and determine which colour tint will minimise your symptoms. They will then help you select glasses and order the lenses with the optimum ReadEZ tint. To find your nearest ReadEZ Test Centre, select Test Centres.
If you suffer from Visual Stress and use a PC, our unique Virtual Overlay software will allow you to tint your screen at the click of a button. Select form an almost unlimited range of tints and cover part or all of your screen with the Virtual Overlay.
Visual Stress is thought to be caused by hyperactivity of certain groups of cells in the brain. The good news is that the symptoms can often be reduced by using a coloured overlay, coloured lenses or by changing the background colour of the screen or tablet that you are looking at.
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.
