optical? is that supposed to be more durable? last i knew cds and dvds had a pretty miserable shelf-life
Here's an article if you want to read more.

They last pretty long when not exposed to your car floor or living room shelves
unless you're stamping them, the chemical dyes used in dvd/cd-r/rw degrades fairly quickly iirc
Yeah, there are cd's from the eighties and nineties that have started shitting the bed already, which in the grand scheme of things is very quickly
I know Microsoft has been working on glass storage under their project silica moniker that they claim has stability measurable in the centuries and really high capacities but I don't know if it's deployed anywhere yet.
The problem with DVDs at least is they use an organic compound for the dye in the reflective disc backing or whatever that slowly breaks down but I believe blu-rays don't. Only issue for BDs is if they're manufactured incorrectly.
yeah.. i remember being told never to store long-term data on cd-r dvd-rs way back in the early 2000s for the photostudio i was working at because the data would likely be corrupted within 10 - 15 years for most of the discs due to breakdown of the chemicals with time
