3 minutes a day. Based on science.
A pilot study from University College London demonstrated that looking at deep red light (670nm) for 3 minutes per day can significantly improve declining eyesight — particularly color contrast vision, which naturally deteriorates with age.
The study was published in The Journals of Gerontology and covered by major news outlets.
If you have an LED monitor, you may be able to replicate the effect by looking at a deep red screen. Click the button below to start a 3-minute red light session with a built-in countdown timer.
Disclaimer: The original study used a specific 670nm LED device. A computer screen may not reproduce the exact wavelength, and no study has tested this method with monitors. This is based on a single pilot study — we make no medical claims. Consult your eye doctor for professional advice.
