In our last post, we discussed options of correcting for astigmatism. Today, we will discuss the newest technology in opticals, specifically digital lenses, for high-definition vision.
Remember the evolution of the television? The clarity of pictures and moving images when we made that much needed upgrade from analog to HDTV? We’ve made the same revolutionary jump in the optometric world too!
From traditional lenses, comes the new and improved digital, free-form lens! Traditional lenses were originally made with the prescription being ground into blank lenses without much other details taken into account. The new digital, free-form lens, however, utilizes a more updated technique to make prescription lens. Computer-controlled surfacing equipment are used to make lenses with much more precision than conventional tools (kind of like 3D printers!).
The best part about these digital lenses are that they are made so that they are highly customized and tailored for you. Some of the details and measurements that are considered in the production of the lenses are:
- How does the frame sit on your face? How far does the frame tilt forward or backward?
- What’s the distance between the front of your eye to the back of the lens?
- What’s the curvature of the glasses? Does it wrap snuggly around your face?
- What’s the distance between your eyes? (This is commonly known as the PD).
- How low does the frame sit on your face? Where exactly are your pupils looking out of the glasses?
All five of these minute details you never would have thought could affect your vision, are all taken into consideration when we customize those lenses for you! Some of our favorite digital lens are the Zeiss Individual SV and the Hoya SV iQ (if you’re looking for single vision lenses), but also the Zeiss Individual 2 and the HOYA iD Lifestyle (if you’re a progressive lens wearer). Imagine seeing the world in a whole new light – in high quality, high definition!
In our next post, we’ll talk about the different lens materials that are used to make your lenses!
