re: Where can I get an updated contact prescription?

Try Visionworks. They also have some contacts in stock so you could possibly walk out wearing them today. They never have mine in stock, but I am very nearsighted.

There are some in Baton Rouge call them even though in the search it says temporarily closed.

The one in metry is open and I got my updated prescription a couple of weeks ago and then wound up ordering the contacts from lens.com. Visionworks does a temperature check and gives you a mask to wear.

Lens.com apparently has an online vision test that you can take with certain limitations.

The yearly prescription has something to do with having a reliable revenue stream, but online tests won't pick up on eye issues like a retinal tear.
