Test your peripheral vision:
If you need reading glasses, please wear them while you use the Amsler grid. The grid should be at about the same distance from your eyes that any other reading material would be.
Cover one eye, then focus on the dot in the center.
VERY IMPORTANT: Report any irregularity or sudden change to your eye doctor immediately.
