Eccentric rings printed on white opaque cards provide exophoric (patients with overconvergence or “wall eyes”) with base-out vision training. The eccentric circles are designed for both base-in and base-out therapy. These paired cards help improve the ability to coordinate the aiming and focusing of the eyes when the eyes tend to aim at a distance farther from you than the point at which you focus them. Improving this skill will enhance the ability to do close work comfortably.
