What if your computer screen could heal you instead of harming you?

In this episode of Sunlight Matters, we’re joined by Dr Peter Veto and Liliana Lettieri, the visionary team behind Pixun — a company pioneering solar-powered, full-spectrum displays that use real sunlight instead of artificial backlighting.

Peter and Liliana share their personal journeys with light sensitivity, screen-induced insomnia, and EMF-related health issues, and how those struggles inspired them to engineer a radically new type of screen — one that brings the entire solar spectrum indoors using fiber optics and rooftop solar collectors.

We dive into:

• Why most screens today are making us tired, sick, and unfocused
• The science behind sunlight exposure, blue light toxicity, and circadian disruption
• How Pixun’s screens deliver natural light through displays, supporting everything from sleep health to vision and cellular function
• Real-world applications for urban living, real estate sun studies, architecture, and workspace wellness
• How tools like shadow mapping and sunlight analysis can optimize solar collector placement for homes and commercial buildings

Whether you’re a parent worried about your child’s screen time, an architect exploring better building orientation, or a company looking to improve employee wellness through sunlight-optimized tech — this episode will change the way you think about screens forever.
