Advances in spectacle lens technology have transformed the appearance and performance of glasses in recent years. The days of metal frames and glass lenses are long gone, as are visible horizontal lines across bifocal lenses. Today, it’s hard to tell what prescription strength lenses contain simply on appearance, due to advances in materials and manufacturing.
As we get older, our eyes struggle to switch quickly between viewing objects at different distances. For patients over forty, varifocal lenses provide sharp and well-defined vision at various distances, with no obvious seams between different lens compositions. Similarly, you’d struggle to identify someone needing a high index prescription, thanks to lens-thinning technology and lightweight materials which fit into a larger array of frames. The advanced technology used to produce digitally surfaced lenses can fully adapt each lens to that eye’s precise visual needs. It’s possible to incorporate a variety of lens coatings, offering benefits from UV protection to blue light reduction. The blue light emitted by computer/smartphone screens can affect sleep patterns, and reducing it is important – especially if you’re in the habit of using phones or laptops at night. Other coatings repel water, grease, scratches and dirt.
