Digital Eye Strain

Couple smiling at a screen

As Americans spend a significant portion of their days fixated on digital devices, they are frequently experiencing digital eye strain.

Your patients of all ages rely on digital devices to stay connected, productive, educated, and entertained. More than 67% of adults report using two or more digital devices simultaneously1.

How Digital Devices Affect Vision

Using digital devices can reduce a person’s blink rate2, sometimes causing eye tiredness and dryness, common symptoms of digital eye strain, which is ocular discomfort felt after only two or more hours in front of a digital screen3.

Your Patients Want Solutions

Nearly 4 out of 5 contact lens wearers are interested in knowing more about reducing eye strain and tiredness associated with digital devices4.

The Winning Technologies Behind MyDay Energys® and Biofinity Energys®

The unique combination of DigitalBoost technology and Aquaform® Technology in MyDay Energys® and Biofinity Energys® lead to robust contact lenses designed to help with eye tiredness and dryness associated with digital device use.

DigitalBoost Technology

DigitalBoost technology is an innovative single vision aspheric lens design that delivers a +0.3D boost, to help eye tiredness associated with digital device use.

DigitalBoost technology may help ease ciliary muscle stress from overworked muscles during digital device use and may help ease accommodative burden. This aids sphere patients’ eyes to better adapt when shifting focus between digital devices and the real world.

DigitalBoost technology wearers were significantly more likely than sphere wearers to say6:

  • Their eyes felt less tired during or after working with a computer*.
  • They didn’t have to strain to see well after some time working with a computer**.
  • Their eyes hurt less when working with a computer.
  • They didn’t have to blink a lot while using the computer at work.
  • They didn’t have heavy eyes at the end of a work day.

Aquaform® Technology

Aquaform® Technology is an advanced material technology that hydrates contact lenses to twice their weight in water7 for natural wettability and incredible comfort all day, which can help eyes to feel less dry, even during times of reduced blinking.

The main challenge with any silicone hydrogel contact lens material is finding the right balance of moisture content, oxygen transmissibility and modulus. CooperVision overcame this challenge by pioneering Aquaform® Technology, with a unique set of structures that are integrated throughout the lens material. More than 24 million wearers experience the great vision and incredible comfort that their eyes deserve thanks to Aquaform® Technology8.

How Aquaform® Technology works:

  • It starts with a proprietary network of long and short silicone chains, which are then purposefully interlinked to deliver the right balance of high oxygen transmission7 and optimal modulus.
  • Powerful hydrophilic arms on the silicone chain network attract and anchor water molecules making it highly compatible with the polymers throughout the entire lens matrix7.

What This Means for Your Practice

With MyDay Energys® and Biofinity Energys®, you have the opportunity to prescribe a lens that can help your patients with eye tiredness and dryness associated with digital device use—exactly what they need and want right now. Giving your spherical contact lens wearers a better lens-wearing experience could lead to higher patient retention and loyalty.
