This clever manufacturing technique throws out the thick bulging curved plastic lens and replaces it with a thin array of concentric prisms that essentially do the same job. |
| [* icon_note] The Fresnel lens has the same large aperture and short focal length, in a fraction of the weight, which is exactly what VR needs, a lens that can function strapped inches from your face and light enough to be supported by your poor neck muscles. | |
| [* black] Bonus round: by varying the size and shape of the concentric prisms, Oculus was able to fine-tune the lens for this specific application, minimizing spherical aberrations, or distortions, that may result from a traditional curved lens. This probably explains the asymmetrical shape. |
