I worked at Oculus on every headset from Rift DK1 to Quest 2 from 2012-2019 and this statement could not be more wrong.

> That was Corning, not Meta.

You need more than a glass maker to build novel optical designs, besides which, none of the headsets at least within that time window used any material from Corning. The lenses in DK1 and DK2 were essentially straight copies of an off the shelf magnifier. The first consumer Rift used a Fresnel lens design that was re-optimized internally off of a design that started at Valve. The design was just the tip of the iceberg though. A colossal amount of engineering work went into manufacturability, especially around coatings. Rift S, Quest, and Quest 2 all used an evolution of that design that took in further advancements done internally within both the product and the research teams. One general note on all of this is that "lens design" for isn't a matter of drawing some curves and throwing it out to a factory.
