According to Duane, a reduced NPC is actually considered the “most consistent clinical sign found in persons with CI28.” The proper target for NPC is varied depending on which study you look at: some use an accommodative target where others use penlights, and a red lens with a penlight (the former has been proposed to help pick up more subtle CIs29). Convergence insufficiency is a sensory and neuromuscular anomaly of the binocular vision system, characterized by a reduced ability of the eyes to turn towards each other, or sustain convergence.. With normal vision, your eyes make a series of adjustments to work together to form a single image. This can cause eyestrain, headaches, or vision problems like blurred or double vision.
