The Screen Generation: Why Digital Eyestrain Is on the Rise
Screens are everywhere—from smartphones and laptops to smart fridges and digital dashboards. While this technology keeps us connected and productive, it’s quietly impacting one of our most sensitive organs: our eyes. At Affinity Optometry, we’re seeing more patients with complaints linked directly to excessive screen time—and the numbers are rising, especially among children and remote workers.
What Is Digital Eye Strain (a.k.a. Computer Vision Syndrome)?
Digital eye strain is a collection of vision and eye-related issues that result from prolonged screen use. It’s often caused by:
Reduced blink rate when staring at screens
Poor lighting or glare
Poor posture or screen placement
Long stretches without visual breaks
Common symptoms include dry eyes, blurred vision, headaches, and neck or shoulder pain.
The Science: How Screens Are Changing Our Eyes Physically
While occasional screen use isn’t harmful, extended exposure—especially daily over years—can start to reshape the way our eyes function and even develop.
1. Increase in Myopia (Nearsightedness)
Recent studies show a strong link between screen time and the rising rates of myopia in children and young adults. Lack of outdoor light and long hours focusing up close can influence how the eye grows, leading to elongation of the eyeball.
2. Disruption of the Tear Film
Blinking less often dries out the surface of the eye, reducing tear quality and leading to symptoms of dry eye—something we see more often in screen-reliant professions.
3. Overworking the Eye Muscles
Prolonged focus on screens can fatigue the eye’s focusing system, particularly the ciliary muscles responsible for shifting focus between near and far distances.
Signs It’s Time for an Eye Checkup
If you're experiencing any of the following, it may be time to book an eye exam:
Frequent headaches after screen use
Blurred vision that worsens throughout the day
Eye fatigue or pain after reading or working
Red, burning, or watery eyes
Increased light sensitivity
These may be early signs of screen-induced eye strain or a developing prescription issue.
Tips to Protect Your Eyes in a Screen-Filled World
The 20-20-20 Rule
Every 20 minutes, look at something 20 feet away for 20 seconds. This simple habit relaxes eye muscles and helps maintain focus flexibility.
Blue Light Filtering Lenses
Ask about our blue-light blocking options—especially if you spend evenings on devices. While they’re not a cure-all, they can reduce glare and sleep disruption.
Ergonomics Matter
Make sure your screen is at eye level, about an arm’s length away, and that lighting is adjusted to reduce glare.
Hydration and Blink Reminders
Stay hydrated and consciously blink more often when on screens. Some apps even send blink reminders.
