Many of us have jobs that require spending hours in front of a computer or laptop screen. That means being prone to eye problems associated with prolonged screen exposure.

According to Dr. Kristine Corpuz-Velasquez, an ophthalmologist and consultant at St. Luke’s Medical Center, “Spending most of your day staring at [the] computer or phone screen can result to digital eye strain or accommodative spasm,” a condition that is characterized by blurred vision, eye fatigue, and headaches.  

To prevent eye strain, Dr. Corpuz-Velasquez suggests the 20-20-20 rule: for every 20 minutes of screen time, you have to look at something 20 feet away for a total of 20 seconds.

Another common culprit for eye problems is the blue light emitted from screens, which could cause more than just headaches, fatigue, and eye irritation.

“Studies suggest that continued exposure to blue light over time could lead to damaged retinal cells. This can cause vision problems like age-related macular degeneration,” an article on Prevent Blindness says. This eye condition affects the center of the retina in the back of the eye, the macula, which can impair vision quickly, making it hard to do daily tasks such as cooking, reading, driving, and even recognizing faces.

To prevent blue light from causing your eyes damage, doctors recommend wearing protective glasses that can block or reduce exposure to blue light. 

Do protective blue light glasses really work?

Blue light-blocking glasses have specially designed lenses that claim to have the capability to filter out the blue light from digital screens.

In a 2017 study, it was concluded that “Blue-light filtering spectacle lenses can partially filter high-energy short-wavelength light without substantially degrading visual performance and sleep quality. These lenses may serve as a supplementary option for protecting the retina from potential blue-light hazard.”

Even though there are only few studies regarding its effectiveness, this type of eyewear is already popular in the market especially among office workers.

Here are a few stylish, non-grade, and transition eyeglass brands that offer protection from blue light.

Tips to prevent digital eye strain

Dr. Corpuz-Velasquez lists other tips to prevent damage to your eyes while working from home, aside from the 20-20-20 rule:

  • Use FDA-approved artificial tears eyedrops for lubrication.
  • Limit glare from screens and work in a room with balanced lighting -- not too bright or too dim.
  • Use dark mode settings when possible (white font against a dark background).
  • Observe good posture. Make sure that your digital screen is at eye-level when seated.
  • Observe a good distance from your screen. The recommended distance is between 18 and 24 inches.
  • Don’t work on screens when lying down or in an awkward position.
  • Avoid having the electric fan or air conditioner blow air directly to your eyes and face.
  • Increase physical activity and limit screen time at night.
