Patented Axial PointSource Optics
This proprietary technology makes it easy to enter undilated pupils, and provides a 25° field of view, resulting in a view of the fundus that's 5X larger than you see with a standard ophthalmoscope in an undilated eye.

The eyecup establishes and maintains proper viewing distance, provides image stability, serves as a pivoting point for panning around the retina, helps with orientation, and screens out ambient light. The eyecup is cleanable and reusable.
