In 1978, the Federal Trade Commission passed a regulation rule known as Ophthalmic Practice Rule or Eyeglass Rule. The rule requires eye doctors (optometrists or ophthalmologists) to give patients their eyeglass prescriptions at no extra cost.

One more thing, please ask your doctor to include PD number (pupil distance) in your prescription.
