Demystifying Your Prescription
Anatomy of a Prescription
You’ve found the perfect frame, you’ve been to the eye doc and you have a prescription in hand. OD, OS, SPH, CYL, PD—say what? Let’s clarify what it all means.
Your Eyes, Your Prescription
The Federal Trade Commission’s Prescription Release Rule is a law that requires eye doctors to give you a copy of your eyeglass prescription after an exam. The rule protects the "portability" of your eyeglass prescription, allowing you to use it to buy glasses from the vendor of your choice. If you feel your eye doctor isn’t being fair about your prescription, you can contact the FTC at (877) 382-4357.
