Stressed Woman

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.

How ReadEZ Can Help You?

Visual Stress is thought to be caused by hyperactivity of certain groups of cells in the brain. Some people with no apparent problems with their eyes report that it is uncomfortable to look at certain patterns, including a page of words, where words appear to move, wobble or flicker, while others see colours or patterns in the words. This tends to make reading for any length of time uncomfortable and can lead to eyestrain, headaches or even migraines.

How ReadEZ Can Help You
