The Kay Accommodative Rock Chart (Hart Chart) is used to improve accommodative flexibility and accuracy by a series of exercises. Therefore, it is a useful alternative home exercise to using flipper lenses. In addition, the chart is of use in treating those with specific literacy difficulties; especially short-term memory, sequencing and tracking that are required for fluent reading.

Each set comprises an identical near and distance chart, with two size options for near viewing. The chart is positioned on the near card to make it easy to view the distance chart with small eye movements. The Kay Accommodative Rock Chart is available in two variations with letters and numbers or with pictures for pre-literate children.

It comes in a pack of either 5 or 50 sets.

The charts are laminated and can be wiped clean.
