Burning Questions
Viewers are seeking clear, evidence-based red and near-infrared light protocols for eye health: correct wavelengths, intensity, and exposure duration. Safety concerns surfaced frequently—especially regarding cataracts, post-surgery eyes, macular degeneration, and implants. Many wanted to know how to distinguish authentic devices, whether cheaper options or LEDs are safe, and how to apply morning sunlight as a substitute.
Others focused on circadian rhythm and melatonin: how to manage light exposure for better sleep, especially among shift workers, older adults, and those in low-sunlight regions. Questions spanned UVA vs UVB benefits, sunscreen timing, and how to safely integrate artificial lighting or SAD lamps for biological balance.
