Reading rulers are ideal for sufferers of visual stress. They can be used not only to help prevent the glare off a white background, but also to track progress on a page. The unobtrusive size makes them convenient for users to carry anywhere with them. The plain rulers have a simple panel with an underline designed for use with diagrams or ordinary reading.
Colours provided are: Orange, Sky Blue, Aqua Blue, Yellow, Grass Green, Pink, Magenta, Celery Green, Jade Green and Purple.
