How Natural Light Therapy Supports Eye Health

I've just returned from a two-week break abroad. It has been an eye-opener (forgive the pun) on many levels—offering time to be still, to read, and to reconnect with nature. Amidst our often-hectic lives, this quiet time brought valuable insights, especially around the healing power of light and nature.
The Truth About Drusen and Inflammation
After reviewing scientific papers and expert literature, it's clear: drusen buildup contributes to inflammation and impedes the vital exchange of nutrients and oxygen to the retina. This is critical for those with Dry Age-related Macular Degeneration (Dry AMD). To protect and potentially reverse the damage, reducing drusen must be a top priority.
Why Sunrise and Sunset Matter for Your Eyes
Ancient cultures—whether through Indian sun salutations or Japanese Tai Chi—engaged in outdoor rituals at sunrise and sunset. These times emit long-wavelength red and near-infrared light, the same spectrum used in Valeda Light Therapy. Scientific studies confirm that this light stimulates cytochrome c oxidase in the eye, boosting mitochondrial function, enhancing energy production, and activating cellular regeneration. This process, known as photobiomodulation, is nature’s way of healing and restoring vision health.
Pro Tip: Spend 10–20 minutes outside at sunrise or sunset. In the UK, sunrise can occur very early during summer, making it challenging to catch the exact sunrise or sunset. Instead, aim for early morning or evening light, as long as your shadow is taller than you. This indicates you're receiving the safer, longer wavelengths of light that support eye health and regeneration.
Why Indoor Light Isn't Enough vs Natural Light
Modern homes—with standard or even double-glazed windows—filter out these healing wavelengths. Most of what gets through is UV, which degrades quickly indoors. So, it’s not just physical movement outdoors that benefits your eyes—it’s the actual light exposure. If you can’t go for a walk, just sit outside, even on your doorstep. Our European neighbors often do—chatting, shelling peas, enjoying the air. A practice worth reviving.
Nature Heals More Than Just Eyes
Spending time in green spaces also lowers cortisol, the stress hormone linked to chronic conditions. Whether it's a stroll in Bolton’s Turton and Entwistle reservoir (which looks like Switzerland!) or time in your garden, Nature builds resilience—mental and physical. Even if mobility is limited, indoor plants can have a similar calming effect.
Updated Valeda Treatment Flexibility
Exciting news from Lumithera, the makers of Valeda: you can now complete your therapy cycle over five weeks instead of three. This gives you greater flexibility, so you don’t have to cancel life’s plans—holidays included!
The Power of Gratitude
Finally, let’s not forget the mental reset. Practicing gratitude helps us appreciate what we have and better face what we don’t. I’m deeply grateful for your time and attention—and hope this post supports your journey to better vision and wellbeing.
Until next week,
Shakti Thakur
