Ra Optics Sunset Lenses

What Are Ra Optics Sunset Lenses?

Ra Optics Sunset Lenses are premium blue and green light blocking glasses designed for evening wear to support circadian rhythm alignment and natural melatonin production. Founded by Matt Maruca, whose background in ancestral health and light biology informs the product philosophy, Ra Optics differentiates itself with broader spectral coverage: the Sunset lenses block 100% of both blue light (400–500 nm) and green light (500–550 nm), compared to most competitors that block only blue light.

The inclusion of green light blocking is based on emerging research suggesting that wavelengths in the 500–550 nm range can also affect melatonin production, though the effect is less pronounced than blue light. Ra Optics positions this broader coverage as providing more complete circadian protection for users who are serious about optimizing their light environment.

How It Works

The Sunset Lenses use precision-tinted CR-39 optical-grade lens material—the same base material used in prescription eyeglasses—rather than the polycarbonate used in most consumer blue light glasses. CR-39 provides superior optical clarity, meaning less distortion and truer visual perception through the tinted lens. The deep amber-red tint filters both blue (400–500 nm) and green (500–550 nm) wavelengths, allowing only longer-wavelength light (red, orange, yellow) to pass through.

The science behind green light blocking is more nuanced than blue light. While blue light in the 460–490 nm range is the primary melatonin suppressor acting on melanopsin receptors, research published in the Journal of Physiology and other peer-reviewed journals has shown that green light can contribute to melatonin suppression at sufficient intensity, particularly in combination with blue light. By blocking up to 550 nm, Ra Optics aims to eliminate both primary and secondary circadian disruptors.

The recommended protocol is the same as other blue-light blocking glasses: wear them for the last 2–3 hours before your target bedtime. The deeper tint means more color shift than blue-only blocking glasses—the visual experience is notably warmer and redder, which some users find more immersive for evening relaxation and others find initially disorienting.

Key Features

• Blue + green light blocking (up to 550 nm): Broader spectral coverage than blue-only blockers, addressing both primary and secondary melatonin-suppressing wavelengths
• CR-39 optical-grade lenses: Premium lens material used in prescription eyewear, providing superior clarity and reduced distortion compared to polycarbonate alternatives
• Multiple premium frame options: Curated frame designs ranging from classic to modern, with an emphasis on aesthetics that make the glasses something you want to wear
• Ancestral health philosophy: Founded on the premise that modern artificial light environments are mismatched with human circadian biology
• Prescription-compatible: Available with prescription lenses for those who need vision correction

Our Testing Experience

We tested Ra Optics Sunset Lenses alongside BON CHARGE Sleep+ glasses for four weeks to directly compare the two approaches. The optical quality difference was immediately apparent: the Ra Optics lenses are noticeably clearer and sharper. Text on screens was crisper, and the amber-red tint felt more uniformly distributed with fewer visual artifacts. This is the CR-39 advantage—it simply produces a better visual experience than polycarbonate.

The deeper tint (blocking green light in addition to blue) creates a more dramatic color shift. Evening TV watching took on a distinctly warm, red-toned quality. Three of four testers preferred this deeper tint after the initial adjustment period, describing it as more "calming" for evening wind-down. One tester found it too dark for activities requiring accurate color perception, such as photo editing.

In terms of sleep onset, our testers reported comparable subjective improvements to the BON CHARGE glasses, with a slight edge for the Ra Optics among the two testers who were most sensitive to evening light. We cannot isolate whether this was due to the green light blocking, the better optical quality, or placebo expectations from wearing a premium product. The research on green light's independent contribution to melatonin suppression is real but less robust than the blue light evidence.

At $169–229 depending on frame selection, Ra Optics costs approximately 50–100% more than BON CHARGE. The premium buys you better lens material, broader spectral coverage, and more refined frame aesthetics. Whether that premium is worth it depends on how seriously you take light optimization and how much you value optical quality in something you wear for 2–3 hours every evening.

The Bottom Line

Ra Optics Sunset Lenses are the premium choice in evening blue-light blocking eyewear, offering the broadest spectral coverage (up to 550 nm) and the best optical quality (CR-39 lenses) of any consumer product in this category. The higher price point is justified for users who want maximum circadian protection and appreciate the difference in lens clarity. For most users, the BON CHARGE Sleep+ provides effective blue-light blocking at a lower price—but for those who want the best available, Ra Optics sets the standard.
