Other countries (i.e. China) have zero problems with achieving this.

• Go to a glasses market

• They quickly scan your eyes w/a machine (1 min, zero cost) to get your prescription

• Pick out frames

• Choose bifocals or not

• 1 hour later, glasses are done, for as cheap as 10$ if you want, although more likely 50$ or so, due to them restricting the supply of cheaper frames which don't look intentionally ugly.

In this US this process takes hundreds of dollars and multiple weeks.

Will California get its act together and allow this to happen before mid year 2029 in ANY in-person or online store?

If someone makes a claim, I will either go there or investigate, or visit the website, and try it. If they do it, even occasionally, for any personalized prescription, even excluding bifocals, then YES immediately otherwise NO at deadline.
