Digital Eyeglass Lenses
Do I need them?
Now that you’ve gotten your annual comprehensive vision exam and your eye doctor has ensured that your eyes are healthy but its time to update your glasses. Whether you’ve worn eyeglasses before or purchasing your first pair, there are hundreds of lens options that you can choose from. In recent years, digital eyeglass lenses have become available and has proven to be a valuable addition to the optical market. This article will discuss what digital lenses are and whether it is right for you.
Digital lenses also known as free-form lenses have been available commercially for many years prior to the entry into the optical market. They are in your cameras, microscopes and telescopes. The same reason why we have them in our equipment is the same reason why you want them in your glasses. Digital lenses offer the most crispness and sharpness in vision. These lenses achieve this by minimizing optical distortion created by high-order aberrations. High-order aberrations are created by irregularities on the front surface of your eye or from conventional eyeglass manufacturing processes. Either way, high order aberrations reduce the crispness and sharpness of your vision and in people that wear progressive lens, high order aberrations can minimize your peripheral vision.
With digital lens surfacing technology now available, your prescription can be taylor made to fit your eyes. With traditional lenses, pupillary measurements are used to help position your eyes behind the lenses. In addition to pupillary measurements digital lenses take into account the angle between your eye and the lens as well as the distance of the lens to the frame. These measurements help to fine tune your prescription allowing you to see a more crisper image.
People with higher prescriptions tend to have higher degrees of aberrations, therefore they will notice a greater benefit from digital lenses. People who wear progressive eyeglasses can also benefit from digital lenses b/c digital lenses minimizes peripheral distortion often seen with traditional progressive lenses. This is a great option for first time progressive wearers.
In my opinion, digital lenses are proving to be very successful and has given people a new insight into high definition viewing. It’s not just for your TV anymore. View life in a whole new way.
