Computer Vision Syndrome (CVS), also called digital eye strain, is a cluster of symptoms that arise from prolonged use of screens. It happens because digital viewing places unusually high demands on the visual system, especially from high energy visible (HEV) blue light and electro-magnetic emissions.
Key symptoms
- Eyestrain, tired eyes, or aching around the eyes
- Blurred or fluctuating vision
- Dry eyes (from reduced blinking)
- Headaches
- Neck and shoulder pain
“Digital eye strain isn’t just a screen problem — it’s a light‑nutrition problem that happens when screens dominate your day, and sunlight disappears from your morning. Light is information. When the only light your body gets is from screens, your biology runs on the wrong data. Photo Nutrition helps people restore the light their biology expects… especially near infrared light (NIR).
Medical literature does not list NIR light as a standard treatment for CVS. However, NIR light is widely studied for photobiomodulation (PBM)—its ability to support cellular energy production, reduce inflammation, and improve tissue recovery. That’s where the connection to eye strain becomes interesting.
Most people treat digital eye strain with blue‑light glasses that at best block or simply reduce blue light emissions. By comparison, near infrared light “counters” HEV blue light and in fact actually supports cellular repair and regeneration. The real fix starts with morning Photo Nutrition that stabilizes your circadian rhythm and the counter effects of NIR light therapy.
