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.
