Hyperacuity Grid

by

Hyperacuity Grid

This uses your hyperacuity to easily locate areas of visual distortion possibly caused by fluid or blood leakage in your retina. Print this page, then cut out the strip of dots below. With one eye shut, gaze at the center of the graph from a distance of about 12 inches (30 cm). Slide the strip from top to bottom of the grid, marking the location of any dots that fall out of line. Repeat periodically, and report any sudden changes to your doctor.
