Arunalight is purpose-built for the ocular region with strictly red light at 670 nm and a conservative, low dose: >
Irradiance: 45 mW/cm²
Time: 3 minutes (auto shut-off)
Dose per session: 8.1 J/cm² (45 mW/cm² × 180 s)
Cadence: every other day
This combo is designed to sit inside the beneficial window—enough to engage mitochondria without pushing into the inhibitory zone. The automatic shut-down and every-other-day schedule do a lot of the “dose discipline” for you.
Wrong intensity: Many panels run far higher irradiance and invite overexposure within minutes—especially dangerous if users keep eyes open.
No ocular-specific dosing: Panels are made for backs/knees, not delicate ocular surfaces; “copy-pasting” body doses to eyes often overshoots.
No built-in guardrails: Without auto shut-off and an every-other-day protocol, it’s easy to “dose stack” and cross the line from help → irritation.
Optical geometry matters: The eye’s optics focus red light onto the retina if the eyes are open. Arunalight is meant for eyes-closed, periocular use at a planned dose.
Panels emit light across a broad field and from a distance, but a significant portion of red light—up to 80%, according to reports—is lost due to reflection and scattering. For precise ocular dosing, a close-proximity, eyes-closed delivery method offers far greater reliability and consistency.
If the goal is eye comfort and mitochondrial support around the eyes, don’t try to hack it with a bright body panel or mask. Use a purpose-built, low-dose, eyes-closed device like Arunalight that keeps you in the sweet spot.
Wavelength for Eye vs. Body Therapy
For eye health, the most studied and effective wavelengths are 670nm (red) and 810–850nm (near-infrared). These wavelengths penetrate the eye with over 95% transmission and target the retina’s high mitochondrial density, supporting cellular energy and potentially slowing degeneration in conditions like macular degeneration and glaucoma. Studies also show benefits from 630nm and 780nm. In contrast, body therapy primarily uses 630–660nm (red) for skin and superficial tissue, and 800–850nm (near-infrared) for deeper penetration into muscles, joints, and bones.
Intensity (Irradiance) Differences
Eye therapy requires lower intensity due to the eye’s sensitivity. Effective treatments typically use 50 mW/cm² or less, with doses around 10 J/cm², to avoid damage. For the body, higher intensities are used—30–100 mW/cm² for skin and 80–100 mW/cm² for deeper tissues—because the skin and underlying structures can tolerate more energy. The power density must be carefully calibrated to avoid overheating or overstimulation, especially in sensitive areas.
Critical Safety Note
Laser light is unsafe for the eyes due to its focused beam, which can concentrate energy and cause retinal burns. LED-based red and near-infrared light is safe for ocular use when properly dosed. Always use FDA-cleared, low-intensity LED devices for eye treatments.
