Digital Lens Technology for a Digital Life

By on

Technology has invaded all aspects of our life. For most, technology has become an addiction, leaving us waiting, wanting and needing the most up-to-date device. Whether it’s the newest tablet, smartphone or wearable technology, we can’t wait to get our hands on tech that improves our lives, entertainment and even well-being. However, one of the biggest advancements in technology is not what we carry in our pockets, wear on our wrist, or keep in our homes; it’s what we wear every day on our faces—our eyeglasses. Digital lens technology has redefined how people see and upped the ante with a new level of customization for glasses-wearers.

How do digital lenses work?
 While there is only a slight difference in ordering digital lenses as opposed to old technology lenses, there is a lot of high-tech work that goes on behind the scenes.

  • Once you get your eye exam and select your frames, your eye doctor or optician will take a series of measurements. Digital lens measurements are extremely precise and measure not only unique characteristics of your eyes but also how your eyes are positioned in your chosen frame and how that frame fits your face.
  • From there, the lenses are sent to a lab. Your prescription is digitally mapped onto lens blanks and diamond cut with sophisticated, laser-guided machines. This high-end technology ensures accuracy to 1/100 of a diopter, which is much more accurate than the traditional abrasive-ground lenses.
  • Next, coatings or tints are added to customize the look of the lens and reduce smudging, glare and scratches. The anti-reflective coating, which is most popular among glasses-wearers, is actually a complicated series of chemical reactions that take place in a giant vacuum chamber!
  • Once the lenses are put in your frames and quality tested, they go back to your doctor for any final fitting adjustments, and then you’re on your way with new high-tech specs.

Are you protecting your eyes?
Another benefit of digital lenses is that they can protect your eyes from your digital life. How many hours do you spend in front of a computer, tablet or smartphone screen each day? If it’s more than a couple hours, you may want to consider computer vision lenses to help relax your eyes and avoid digital eye strain. Plus, those screens emit a harmful blue light that can, over time, damage your eyes and cause diseases like macular degeneration. If you’re a serious techy, you should opt for UNITY lenses with BluTech, which are specially formulated lenses that filter out harmful light and sharpen contrast.

The bottom line
Because they offer such a high level of customization, UNITY digital lenses will help you see more clearly no matter what you use them for. And if you’re a progressive-wearer, you’ll appreciate how easy it is to adapt to them. Most importantly, you don’t have to break the bank for this high-tech upgrade. With vision coverage, digital lenses are just a few dollars more than older technology lenses. VSP members also get exclusive access to special pricing on UNITY lenses.
