Screen time is damaging our eyes—and that’s harming our ability to lead

We talk a lot about visionary leadership. You know, the ability to see around corners, spot emerging patterns, and imagine futures that don’t yet exist. These are all very important activities for strategic work. But something we rarely consider is what happens when the physical instrument of vision itself is under siege. Said more bluntly, what happens when our eyes succumb to the daily assault of screen time?

I recently spoke with Dr. Valerie Sheety-Pilon, SVP of clinical and medical affairs at VSP Vision Care, whose organization has spent three years tracking the state of vision health in the American workforce. The data she shared stopped me cold—and it reframed how I think about the infrastructure of creative, imaginative work. Here are three of my takeaways.

Insight #1: The Visual Crisis Is Accelerating Faster Than We Think

Three years ago, VSP’s Workplace Vision Health Report found that 50% of workers were experiencing at least one eye issue. I would definitely fall into that category—I have spare pairs of plus-one readers in every room in our house. But by last year, that number had climbed to 63%. Today it’s 66% and rising. That’s a 16-percentage-point jump in just three years, and it spans both desk workers and non-desk workers alike.

The culprit isn’t mysterious. We are now spending upward of 100 hours a week in front of screens: phones, tablets, monitors, and televisions. That sustained “visual load,” as Sheety-Pilon calls it, is generating screen-related visual discomfort at a rate our workplaces haven’t been designed to absorb. The downstream effects, according to VSP’s research, are reduced productivity, diminished ability to focus, and a declining quality of work output.

When I asked Sheety-Pilon whether visual fatigue might also affect higher-order thinking—the kind of imagination, problem-solving, and creative association that I call wonder —she didn’t hesitate. “There are studies that connect visual fatigue as a component of that imaginative deliverable of creativity,” she told me. “High visual load is impacting cognitive health as part of that.”

Insight #2: The Body Is a System, Not a Collection of Silos

This is the point where Sheety-Pilon’s perspective aligned deeply with my own perspective about what we need in our current Imagination Era. In my book Move. Think. Rest., I point out that our sentient intelligence constantly picks up cues and data through our bodies that inform and enrich our cognitive, rational decision-making. We are hardwired to use our whole selves, not just our prefrontal cortex.

Sheety-Pilon frames it as the “visual sensory capacity,” one critical component within a dynamic, interconnected sensory system. “If we improve our vision, and then our hearing, and then the other senses that all come together,” she explained, “we can get that perfect package where we can be the best we can be every day.”

In other words: The eye is not an isolated organ. It is a gateway to neural tissue, to sensory processing, and to the imagination itself. When we treat vision health as a stand-alone wellness checkbox rather than organizational infrastructure, we are, as she put it, failing to understand “the connection between ocular health, systemic conditions, and overall well-being.”

This resonates with what neuroscientist John Medina writes about in Brain Rules for Work, which argues that ideally we should be stepping away from the desk every 35 to 40 minutes, not as a perk, but as a neurological necessity for sustained high performance.

Insight #3: Vision-Forward Culture Is a Leadership Responsibility, Not an HR Benefit

When I pushed Sheety-Pilon beyond ergonomic tactics—beyond the blue-light glasses and screen-distance reminders—and asked what a genuinely vision-forward organizational culture might look like, her answer was pointed: “Allowing the time and space, encouraging the moments of breaks.” Organizations that prioritize health literacy within the employee network can significantly shape work culture.

She also introduced me to the 20-20-20 rule: For every 20 minutes of near-work screen time, take a 20-second break and look at something at least 20 feet away. It’s the ocular equivalent of what I call movement hygiene in the MTR framework: deliberately alternating between modes of engagement to preserve the capacity for both rigor and wonder. I’ve been giving this one a try and feel my eyes relax immediately!

The leaders and organizations that will thrive in the Imagination Era won’t just invest in cognitive tools or AI capabilities. They’ll protect and cultivate the full sensory capacity of their people. Because you cannot lead with vision (metaphorical or otherwise) if you’ve systematically depleted the organ that makes vision possible.

As Sheety-Pilon summarized near the end of our conversation, “You have better quality of work. You have the focus and the ability to deliver better work when you have a supportive employer that understands the importance of overall mental health and visual and physical well-being.”

The hidden cost of screen-era work isn’t burnout or disengagement, it’s the slow erosion of the very sensory capacity leaders need most. Visionary leadership starts with healthy vision. It’s time to build the organizational infrastructure to protect it.
