A novel optical design form for a biocular lens arrangement having a large format focal plane and large eye relief zone is disclosed. Key aspects of a large format biocular lens arrangement are: Lightweight plastic design for all but outermost lens, where more durable glass is desired; a large front aperture for comfortable eye motion; improved eye channel overlapping field of view with minimal distortion; and full color resolution.
