The Complete Guide to Becoming An Ophthalmic Laboratory Technician

Chapter 1: What Does a Ophthalmic Laboratory Technician Actually Do?

What This Job Really Is

Imagine a workshop where every item that comes in has a written prescription attached, and your job is to turn a flat piece of plastic or glass into a lens that corrects someone's vision. That's the core of what an ophthalmic laboratory technician does. You might work in a lab behind a retail eyeglasses store, or in a large industrial facility that makes lenses for hundreds of optical shops across the country. The setting changes, but the workflow is essentially the same: you take a prescription, you use machines to cut and shape a lens to match that prescription, and you mount it into a frame that the customer (or a shop) has chosen.

Let's be clear about one thing upfront: this is not a job where you work with patients. You will rarely, if ever, meet the person whose glasses you're making. Your interaction is with paper — or more likely, computer files — containing numbers that mean something specific: the sphere (how nearsighted or farsighted someone is), the cylinder and axis (how much astigmatism they have), and the pupillary distance (the distance between their pupils). You'll also see progressive or bifocal prescriptions, which adds a lower section to the lens for reading. Understanding what these numbers mean is part of trainin, and most labs will teach you the basics on the job.
