Good-Lite Z-Axis Accommodative Rock Charts are vision therapy tools for distance-to-near focusing exercises designed to help patients develop accommodative facility and control. They can be prescribed for home-based exercises that help patients become more aware of, and practice control over, their focusing mechanisms.

By positioning a distance chart and a transparent near card directly in front of one another, patients can practice shifting the accommodative plane of focus from distance to near and to points in between. As one plane comes into focus, the other becomes blurred. This arrangement isolates the z-axis from the x- and y-axes, highlighting focusing as a distinct experience from eye tracking.

These charts can be prescribed by primary care optometrists for home exercises or used as part of a vision therapy program. They provide a learning experience for patients with accommodative dysfunctions or emerging presbyopia. Available selections include distance styrene charts, paper distance charts, a clear bullseye, clear near cards, and opaque near cards. Choose the required chart or card from the available options.

Patient-oriented instructions are included.
