a delineation between the first transparency region and the second transparency region,
wherein the delineation extends across a width of the single lens,
wherein the difference between visual light transmission of the first transparency region and the second transparency region is between 20% and 80%, and
wherein a user can simultaneously look through the single lens with both eyes of the user when the single lens is worn by the user.
2. The lens of claim 1 , wherein the lens is partially enclosed by a frame.
3. The lens of claim 1 , wherein the lens is fully enclosed by a frame.
4. The lens of claim 3 , wherein the frame comprises a helmet, and wherein the lens comprises a helmet visor.
5. The lens of claim 1 , wherein the second transparency region extends completely across a visual field of the user.

7. The lens of claim 1 , wherein the delineation extends across the width of the lens in a line parallel to a top edge of the lens.
8. The lens of claim 1 , wherein a first lateral edge portion of the lens is configured to be disposed near a right side of the user's face during use, and wherein a second lateral edge portion of the lens is configured to be disposed near a left side of the user's face during use.
9. The lens of claim 1 , wherein the lens comprises composite layers, wherein the first transparency region is formed on a first layer and the second transparency region is formed on a second layer.
10. The lens of claim 1 , wherein the lens is shatter-resistant.
11. A lens comprising:
a first transparency region that is disposed at an upper portion of the lens;
a second transparency region that is disposed at a lower portion of the lens, the second transparency region being less transparent than the first transparency region;
a delineation between the first transparency region and the second transparency region; and
a nose cutout,
wherein the delineation extends across a width of the lens, and
wherein the delineation extends across the lens above the nose cutout.
12. The lens of claim 11 , wherein the lens comprises composite layers, wherein the first transparency region is formed on a first layer and the second transparency region is formed on a second layer.
13. The lens of claim 11 , wherein the delineation extends across the width of the lens in a line parallel to a top edge of the lens.
14. The lens of claim 11 , wherein the delineation comprises an arched line.
15. The lens of claim 11 , wherein a first lateral edge portion of the lens is configured to be disposed near a right side of the user's face during use, and wherein a second lateral edge portion of the lens is configured to be disposed near a left side of the user's face during use.
16. A lens comprising:
a first transparency region that is disposed at an upper portion of the lens;
a second transparency region that is disposed at a lower portion of the lens, the second transparency region being less transparent than the first transparency region;
a delineation between the first transparency region and the second transparency region; and
a nose cutout that bisects the delineation,
wherein the delineation extends across a width of the lens, and
wherein the lens is configured such that both eyes of a user can simultaneously look through the lens.
17. The lens of claim 16 , wherein the lens comprises composite layers, wherein the first transparency region is formed on a first layer and the second transparency region is formed on a second layer.
18. The lens of claim 16 , wherein the delineation extends across the width of the lens in a line parallel to a top edge of the lens.
19. The lens of claim 16 , wherein the delineation comprises an arched line.
20. The lens of claim 16 , wherein a first lateral edge portion of the lens is configured to be disposed near a right side of the user's face during use, and wherein a second lateral edge portion of the lens is configured to be disposed near a left side of the user's face during use.
