Lens Rulebook
Two federal rules make your eyeglass and contact lens prescriptions yours to take anywhere. This site explains them, with the words to use and buying guides.
I am Dan Swenson, a data nerd who is also a Minnesota workers' compensation attorney and a city council member. I build these sites as a hobby to make public records, government rules, and license registries easy to find and use. The tools are free. The network pays for itself through disclosed referral links and a few optional paid guides.

Lens Rulebook is an independent educational publication written by a Minnesota attorney. It is not an eye clinic, not a law firm acting for you, and not affiliated with the Federal Trade Commission. Nothing on this site is legal or medical advice about your situation, and reading it does not create an attorney-client relationship.
The rights described here come from two federal regulations enforced by the FTC: the Eyeglass Rule (16 CFR Part 456) and the Contact Lens Rule (16 CFR Part 315). Citations are included so anything on this site can be verified against the rule text.
