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.
Ingredients & Purity
High-quality acetate frames and CR-39 lenses. Available in multiple lens tints (Sleep/Amber) to suit specific circadian needs.
Scientific Evidence
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.
