Circadian & Light

Ra Optics is the industry leader in precision optics for circadian health, utilizing proprietary pigments that provide a sharp 550nm cutoff. Unlike most competitors, they use high-quality CR-39 plastic lenses which offer superior optical clarity compared to cheap polycarbonate.

Bon Charge (formerly BluBlox) offers laboratory-tested lenses that block 100% of the blue and green light spectrum from 400nm to 550nm. Their frames are exceptionally high quality, and they offer prescription, reading, and non-prescription options.

BlockBlueLight offers the best balance of clinical-grade spectrum accuracy and affordability. Their NightLens is specifically designed to block 100% of blue and green light up to 550nm, backed by accessible spectral analysis reports.

The MitoPRO 300 is the industry benchmark for mid-sized panels, offering a quad-wavelength output (630nm, 660nm, 830nm, 850nm) that targets both surface skin and deep tissue. It features a flicker-free driver and very low EMF at treatment distances, making it ideal for circadian rhythm entrainment and recovery.

The BioMax series is the most advanced panel on the market, utilizing a patent-pending 7-wavelength R+/NIR+ spectrum that includes 480nm blue light for circadian rhythm synchronization. It provides the highest irradiance of any panel in its class.

Philips is the industry leader with the most robust clinical backing. The HF3670 uses high-CRI LEDs that accurately mimic the spectral progression of a natural sunrise, which has been shown in independent studies to improve the 'cortisol awakening response'.

Lumie is a specialist light therapy company, and the Luxe 750D is a Class I Medical Device in Europe. It features a dedicated low-blue light setting for the evening, which is critical for protecting melatonin production before sleep.

Widely considered the gold standard by experts at the Center for Environmental Therapeutics (CET), this lamp provides a massive 12x16 inch light surface that ensures 10,000 lux at a comfortable 12-14 inch distance. Its height-adjustable stand and downward-tilting head mimic the angle of the sun, which is critical for stimulating the lower retina where circadian-sensitive cells are concentrated.

The Box Elite is a medical-grade device frequently used in clinical trials for Seasonal Affective Disorder. Its heavy-duty metal construction and high-quality internal components make it a lifetime investment for circadian health.

The best-in-class option for those who need portability or have limited desk space. It offers adjustable color temperature and brightness levels, allowing for customization that larger 'box' lamps usually lack.

Philips is the only brand in this category with extensive peer-reviewed clinical data proving their specific light curves improve waking mood and energy. The HF3670 features high-CRI LEDs that mimic the solar spectrum without the UV hazards or flicker found in cheaper units.

Lumie is a specialist light therapy company, and the Luxe 750D is a certified Class I medical device in Europe. It features a dedicated low-blue light 'sunset' mode to promote melatonin production before bed, which most sunrise-only clocks lack.

Ocushield is the world's first and only medically rated blue light blocking screen protector. Developed by optometrists, it effectively filters harmful blue light (380-460nm) while maintaining high color fidelity and screen clarity.

Iris is the most advanced blue light filtering software available, going beyond simple color shifting to address Pulse Width Modulation (PWM) flicker. It allows for granular control over color temperature and brightness without increasing screen flicker.

f.lux is the original pioneer of circadian-aware screen filtering. It automatically adjusts your screen's color temperature based on your local sunrise and sunset, reducing blue light exposure as you approach bedtime.

The Manta Sleep Mask is the gold standard for circadian optimization due to its guaranteed 100% blackout capability and modular design. By eliminating all light leaks, it prevents the suppression of melatonin, even in bright environments.

Utilizing proprietary TEMPUR material, this mask offers a high-density light barrier that molds perfectly to facial contours. It is specifically designed to block light around the nose bridge, a common failure point for other masks.

Swanwick is the brand that popularized blue blockers for sleep. Their orange 'Swannies' are effective at blocking blue light and are a reliable, well-reviewed entry point for those new to circadian optimization.

The Hooga HG300 is the best entry-level panel for those on a budget. It provides the standard 660nm and 850nm wavelengths with respectable irradiance levels for targeted treatment.

The Hatch Restore 2 excels in user experience and 'habit stacking.' While it has less specific clinical hardware testing than Philips, its integrated routine builder helps users maintain a consistent circadian rhythm through light and sound cues.

Beurer offers a scientifically sound alternative for those who find Philips and Lumie too expensive. It provides the essential 2,000 lux (at close range) needed to influence the circadian clock without the high-end price tag.

The Restore 2 combines a sunrise alarm with a high-quality sound machine and a minimalist aesthetic. While it lacks the medical-grade clinical data of Philips or Lumie, its user experience and 'wind-down' routines are superior for habit formation.

EyeJust offers a high-performance physical filter that blocks the most harmful wavelengths of blue light (up to 50% of 440-460nm) without significantly altering the screen's color profile.

The Alaska Bear mask is the best entry-point for circadian health, using 19 momme natural mulberry silk. It provides a breathable, hypoallergenic light barrier that is far superior to synthetic polyester masks found in retail stores.

Nodpod combines light blocking with Deep Pressure Touch (DPT). This dual-action approach not only optimizes the circadian rhythm through darkness but also lowers cortisol levels through gentle pressure, aiding sleep onset.

Joovv is the most recognized name in RLT and holds the most regulatory clearances. The Solo 3.0 includes 'Ambient Mode' specifically designed for nighttime use to support circadian health without disrupting melatonin production.
