The disparity between the images seen in each eye affects our depth perception similar to the depth of field effect from lens. If the vergence point (where eyes are focused) is further from our eyes, the range of depths for which our eyes cannot visibly distinguish between is larger. If the vergence point is closer, then the range of depths is smaller.
