    • An eyepiece for a night vision goggle (NVG) system includes a first lens element axially aligned with second and third lens elements. The first, second and third lens elements are sequentially positioned between a viewer and an object formed on a screen surface. The first lens element is formed as a doublet having two cemented elements. The second lens element includes a convex surface facing the doublet and a concave surface facing toward the third lens element. The third lens element includes a first convex surface facing the second lens element and a second convex surface facing the object. The second lens element is formed with two even aspheric surfaces comprised of only even coefficients and is substantially uniform in thickness.
