I am one of them — within reason, but how much truth is there to this lore?

Make no mistake: higher-quality glass makes for better optics.

Better glass here refers to glass that has been stored for a decade or longer. Colloquially speaking, glass is a semi-solid liquid. Storing glass for decades allows it to relax internal stresses introduced through manufacturing. It stabilizes its amorphous structure, which results in superior optimal optical quality. For high-precision lenses, even the slightest imperfection can be a problem, so long-term storage before grinding ensures superior performance.

At some level, storing optical glass is similar to curing wood. It takes a while for both materials to achieve a stable state. Uncured wood warps, cracks, or shrinks unpredictably. Cheaply built houses “move” if wood above a specific moisture level is used. Optical glass does not flow like…
