16 CFR Part 456 ; Agency Information Collection Activities: Review; Comment Request Ophthalmic Practice Rule (Eyeglass Rule): FTC Project No. R511996
The pupillary distance (PD) should be done by the dispensing optician who is trained to suggest eyewear based on the patients needs. The PD may very based on the application and the patients working distance.. I have had Prescriptions with the PD on them and it was not correct for the application that the patient wanted the glasses for. Because of the incorrect PD the patient may experience visual discomfort, headaches, or other vision problems. Glasses are not a boxed item that is mass produced. Glasses are custom made medical devices that should not be viewed as an item that can be ordered without the direct help of a optician or optometrist. There should be more regulation on the sale of eyewear and contacts rather than less regulation. Seeing is very important to our every day activities. Seeing correctly depends on the correct fitting of glasses with the correct measurements!
