1. An eyepiece for projecting an image to an eye of a viewer, the eyepiece comprising:
a first planar waveguide positioned in a first lateral plane at a first longitudinal position, wherein the first planar waveguide comprises a first diffractive optical element (DOE) disposed at a first lateral position in the first lateral plane, the first longitudinal position being measured along an axis normal to the first lateral plane;
a second planar waveguide positioned in a second lateral plane adjacent to the first lateral plane and at a second longitudinal position, wherein the second planar waveguide comprises a second DOE disposed at a second lateral position in the second lateral plane, the second lateral position being different from the first lateral position and the second longitudinal position being different from the first longitudinal position;
a third planar waveguide positioned in a third lateral plane adjacent to the second lateral plane and at a third longitudinal position, wherein the third planar waveguide comprises a third DOE disposed at a third lateral position in the third lateral plane, the third lateral position being different from the first lateral position and the second lateral position and the third longitudinal position being different from the first longitudinal position and the second longitudinal position; and
an optical filter positioned between the second planar waveguide and the third planar waveguide, wherein the optical filter is disposed at the third lateral position.
