📝 New blog post by Dr. Alexander Wunsch, M.D., Ph.D. One of the world’s leading experts in photobiology breaks down how to use sunlight intelligently—for healing, not harm. 📖 Read the full article on our website: raoptics.com/blogs/news Sunlight is essential for life. It boosts mood, energy, and healing. But like any medicine, the dose and timing matter. Too little = deficiency. Too much = damage. According to Dr. Wunsch, sunlight’s benefits depend on intelligent use—not blind exposure. Gradual adaptation is key, and after a therapeutic dose (~20–30 mins), more isn’t better—it’s harmful. And protection? Non-negotiable. But most sunglasses block circadian light and some block infrared—the very wavelengths your body needs. That’s why we created BlueSync: A lens that specifically filters the harmful and protects the helpful. It’s not about more sunlight. It’s about smart sunlight.
