Digital eye strain (also referred to as computer vision syndrome [CVS], is a condition characterized by visual disturbance and/or ocular discomfort related to the use of digital devices.

As an emerging public health concern, digital eye strain results from a range of stresses on the ocular environment.

An estimated 50 to 90 percent of digital device users experience symptoms of digital eye strain. Studies suggest multiple factors are associated with CVS.1,2

Nationwide concern
Americans have reported experiencing the following symptoms associated with digital device use:3

• 32.4 percent report experiencing eye strain
• 27.2 percent report experiencing dry eyes
• 27.7 percent report experiencing headaches
• 27.9 percent report experiencing blurred vision
• 35 percent report experiencing neck and shoulder pain

Close to 80 percent of Americans report using digital devices-including TV-in the hour before going to sleep, with almost 55 percent in the first hour they are awake.

Similarly, American adults report their children experience the following after being exposed to two or more hours of screen time:3
• Headaches (8.8 percent)

• Neck/shoulder pain (5 percent)

• Eye strain, dry or irritated eyes (9.1 percent)

• Reduced attention span (15.2 percent)

• Poor behavior (13.3 percent)

• Irritability (13.5 percent)

Addressing digital eye strain
A 2018 study investigated the influences of smartphone use on ocular symptoms, status of the tear film, and oxidative stress indices in the tears and at the ocular surface.4
Results found that smartphone use could not only aggravate subjective symptom scoring indices of dry eye but also induce tear film instability and oxidative stress indices in the tears and at the ocular surface.

Suggested management strategies for digital eye strain include:4
• Correcting refractive error, including astigmatism and presbyopia
• Managing vergence anomalies
• Managing accommodative anomalies
• Blinking exercises/training to maintain a normal blinking rate
• Lubricating eye drops to help alleviate dry eye-related symptoms and/or increasing ambient humidity with the use of a room humidifier or moisture-loss preventing glasses
• Prescribing spectacle color filters, especially blue light-absorbing filters
• Computer or gaming glasses with decentered optics (creating small amounts of base-in prism)
• Attention to work and recreational digital device ergonomics

I believe that the amount of time patients report using digital devices is well-underestimated. 

Prevention
Depending on the cell phone manufacturer and operating system, a mobile phone may be equipped to monitor how much time the owner spends using the device, as is seen in the latest iPhone update. 

Other manufacturers allow for programming downtime, setting locked time limits on applications for the individual or shared family users, and setting content blocking.

Prevention is the main strategy for management of digital eye strain. This includes ensuring an ergonomic work environment and visual hygiene practice through patient education.

Be a “dry eye hero” and share cell phone screen-time monitoring information with your patients so that they can be proactive participants in their ocular health.
