BON CHARGE Sleep+ Glasses

What Are BON CHARGE Sleep+ Glasses?

BON CHARGE Sleep+ Glasses are amber-lens blue-light blocking glasses designed to be worn 2–3 hours before bed to support natural melatonin production and circadian rhythm alignment. Unlike clear-lens "blue light glasses" marketed for daytime computer use, the Sleep+ line uses deep amber lenses that block 100% of blue light in the 400–500 nanometer range—the specific wavelength band that research has shown suppresses melatonin secretion.

A widely cited Harvard Medical School study found that evening blue light exposure can suppress melatonin production by up to 85% and shift circadian rhythm by up to 3 hours. The premise behind blue-light blocking glasses is straightforward: by filtering out this wavelength before bed, you allow your body's natural melatonin production to proceed unimpeded by artificial light from screens, LED bulbs, and overhead lighting.

How It Works

Melatonin, the hormone that signals your body to prepare for sleep, is primarily regulated by light exposure to specialized photoreceptor cells (intrinsically photosensitive retinal ganglion cells, or ipRGCs) in your eyes. These cells are most sensitive to blue light in the 460–490 nm range. When blue light hits these receptors in the evening, it signals the brain's suprachiasmatic nucleus to suppress melatonin release, effectively telling your body it is still daytime.

BON CHARGE Sleep+ lenses use a deep amber tint that absorbs wavelengths across the full 400–500 nm blue light spectrum. The result is that ambient room light, screen light, and LED lighting reach your eyes without the melatonin-suppressing wavelengths. The recommended protocol is to wear them for the last 2–3 hours before your target bedtime, allowing melatonin to rise naturally.

The amber tint does alter color perception—everything takes on a warm, orange-yellow tone. This is a direct consequence of effective blue-light blocking and is actually a useful indicator: if the lenses do not meaningfully shift your color perception, they are likely not blocking enough blue light to affect melatonin. Clear-lens blue light glasses, by contrast, block only 5–20% of blue light and do not produce a noticeable color shift, which is why sleep researchers generally consider them insufficient for circadian purposes.

Key Features

• 100% blue light blocking (400–500 nm): Deep amber lenses filter the complete melatonin-suppressing wavelength band, unlike clear lenses that block only a fraction
• Evidence-based approach: Aligned with Harvard and other peer-reviewed research showing 85% melatonin suppression from evening blue light exposure
• Multiple frame styles: Available in prescription and non-prescription options across various frame designs for comfort and aesthetic preference
• Lightweight construction: Designed for 2–3 hours of comfortable evening wear, with spring hinges and anti-slip nose pads
• Carrying case and cleaning cloth included: Practical accessories for daily use and travel

Our Testing Experience

We had four team members wear BON CHARGE Sleep+ glasses for three weeks, each beginning wear at 8:30 PM with a target bedtime of 11 PM. Three of the four reported subjective improvements in sleep onset—falling asleep felt faster and more natural, with less of the wired, alert feeling that often accompanies evening screen use. One tester, who already practiced strict screen-off protocols after 9 PM, noticed minimal additional benefit.

The amber tint takes a day or two to adjust to visually. Watching television, reading on a tablet, or browsing your phone is entirely possible, though colors are shifted toward warm tones. We found the glasses most useful on evenings when avoiding screens was impractical—late work sessions, evening movie watching, or scrolling before bed.

At $90–120 depending on frame style, the Sleep+ glasses sit in the mid-range. Ra Optics Sunset Lenses ($169–229) offer broader spectral coverage (blocking green light up to 550 nm in addition to blue) and premium CR-39 optics, but at a significant price premium. Clear-lens blue light glasses from brands like Felix Gray or Warby Parker are less expensive but block far too little blue light to meaningfully affect melatonin—sleep researchers consistently note that clear lenses are cosmetic rather than functional for circadian support.

Build quality is good for the price range. The frames feel sturdy without being heavy, and the spring hinges accommodate different head sizes without discomfort during extended wear. After three weeks of nightly use, the lenses showed no scratches or coating degradation. BON CHARGE also offers a Sleep+ range with different lens tints—their red-tinted lenses block even more of the spectrum (similar to Ra Optics), though the amber Sleep+ remains their most popular and well-reviewed model. The company provides a 30-day return policy, which gives enough time to evaluate whether the glasses make a subjective difference in your sleep.

The Bottom Line

BON CHARGE Sleep+ Glasses are an effective, evidence-aligned tool for evening blue light management at a reasonable price point. The 100% blue light blocking across the 400–500 nm range is consistent with the research on melatonin suppression, and our testers experienced subjective sleep onset improvements. They are not a substitute for good sleep hygiene overall, but for anyone who uses screens in the evening and struggles with falling asleep, they address one of the most well-documented circadian disruptors at a fraction of the cost of premium alternatives.
