Sleep Blue Light Blocking Glasses
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.
Quality & Materials
High-quality acetate frames and CR-39 lenses. Available in multiple lens tints (Sleep/Amber) to suit specific circadian needs.
Evidence & Testing
Lenses are tested in a laboratory environment in Australia to ensure they meet the specific spectral requirements for circadian rhythm protection.
Brand Transparency
One of the few brands that publicly displays their spectral transmission reports for every lens type they sell.
Value Assessment
Premium pricing but offers frequent sales and a significantly better build quality than entry-level sleep glasses.
Why Not Alternatives?
They provide specific lab reports for their lenses, whereas brands like Gunnar or Felix Gray focus primarily on digital eye strain (daytime use) and fail to block the green light necessary for optimal nighttime melatonin production.

Ra Optics
Sunset Lenses (Clyde Frame)
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.
BlockBlueLight
NightLens Blue Light Blocking Glasses
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.
Swanwick
Classic Night Swannies
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.
Mito Red Light
MitoPRO 300
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.
