In today's fast-paced digital world, our eyes are constantly exposed to screens and off-screen activities, leading to symptoms of digital eye fatigue and dryness. To address these issues, CooperVision, a leading contact lens manufacturer, has developed Digital Zone Optics - a lens design specifically tailored to meet the demands of our digital lifestyles. This article explores the benefits of Digital Zone Optics, the development behind it, and how it can alleviate eye strain caused by excessive digital device usage.

Understanding Digital Zone Optics

Digital Zone Optics is an innovative lens technology integrated into certain newer CooperVision contact lenses (such as Biofinity Energys). CooperVision also calls it DigitalBoost. It is designed to reduce the stress on the eyes' focusing muscle, which can become strained due to prolonged periods of focusing on short distances such as when looking at digital devices or reading books. Lenses with Digital Zone Optics are comprised of multiple front-surface aspheric curves which distribute power more evenly in order to simulate the more positive power from the center of the lens. This design helps the eyes effortlessly shift focus between on-screen and medium to longer-distance off-screen activities, allowing for a more comfortable viewing experience without impacting long-distance vision.

When we view objects up close, a muscle in our eyes contracts and relaxes to change the shape of the lens, enabling us to focus at different distances. This constant muscle movement is comparable to stretching and releasing a rubber band repeatedly, which eventually causes fatigue. Similarly, the repetitive contraction and relaxation of the eyes' focusing muscle during digital device usage can lead to eye tiredness. CooperVision's Digital Zone Optics addresses this issue by reducing the workload on the eyes' focusing muscle. By optimizing the lens design, the strain caused by prolonged near work is reduced, resulting in decreased eye fatigue and improved visual comfort.

Benefits of Digital Zone Optics (DigitalBoost)

  1. Reduced Eye Tiredness: The lens design helps alleviate eye tiredness caused by exhaustive use of digital devices. By minimizing the strain on the eyes' focusing muscle, users can enjoy extended periods of digital screen time without experiencing excessive fatigue.
  2. Enhanced Comfort: Contact Lenses with Digital Zone Optics also feature Aquaform technology, another proprietary technology from CooperVision. Aquaform locks in moisture, providing long-lasting comfort throughout the day. This is particularly beneficial for individuals who experience dryness due to reduced blink rate associated with prolonged screen use.
  3. Effortless Gaze Shifting: With the integration of Digital Zone Optics, contact lens wearer can more easily shift their gaze between on-screen and off-screen activities. This smooth transition helps reduce eye strain and allows for a more natural visual experience.

Development and Availability

CooperVision released Digital Zone Optics in 2016 to cater to the growing needs of individuals living a digital lifestyle. This lens technology is available for the correction of myopia or hyperopia, combining cutting-edge aspheric design principles and years of research to optimize visual comfort and reduce the effects of digital eye fatigue. Check with your eye care professional. They can guide you in determining whether these screen-optimized contact lenses for sphere wearers are suitable for your specific visual needs and digital lifestyle.
