don't know about spectacles but the verge's article about it quote someone saying it's about 10k to make this:

> As Meta’s executives retell it, the decision to shelve Orion mostly came down to the device’s astronomical cost to build, which is in the ballpark of $10,000 per unit. Most of that cost is due to how difficult and expensive it is to reliably manufacture the silicon carbide lenses. When it started designing Orion, Meta expected the material to become more commonly used across the industry and therefore cheaper, but that didn’t happen.
