Prescription spectacle lenses to reduce the progression of myopia consist of spectacle lenses with additional physical optical design lens elements. In addition to optical correction of myopic refractive error, these lenses are intended to be used by children who have myopia to reduce the rate of myopia progression. The lenses are mounted within a spectacle frame classified under 886.5842.
An ophthalmic lens made of glass or plastic that is manufactured in accordance with a specific patient prescription (custom-made) and intended to be worn in front of the eyes to correct the refractive errors of that patient's eyesight, e.g., refractive ametropia (myopia, hyperopia and astigmatism), and possibly to protect the eyes against radiation or mechanical hazards; it has no additional specialized features. This device may require cutting to enable it to be mounted into a selected spectacle frame for patient wear.
