Binocular vision (Stereoscopy) is the ability to align and focus both eyes accurately on an object and then combine the visual images from each eye into a single, clear three dimensional perception. Difficulty seeing in 3D can arise when eye fatigue occurs, forcing the eyes to make adjustments to focus simultaneously on images that are near and far away.
Symptoms indicating a potential problem viewing images in 3D can vary, but some common symptoms include headaches, blurred vision, nausea and dizziness.
