Whilst analysing the pre-seen, I came across the ideas relating to 3D printing and the concept of using 3D printing technology to produce frames and lenses. Here’s a YouTube video that I found to demonstrate the process.

If 3D printing technology proves to be a success, it could remove the need for opticians to stock frames and lenses, printing items “just in time” to meet customer requirements. In time, customers may also be able to create and design their own glasses.
