What the device does.
- + Two Magnum versions — a nighttime amber/red lens and a daytime clear "computer" lens — on the same large metal frame
- + Nighttime lens stated to block blue and green light across roughly 400-550 nm
- + Non-prescription, reader, and prescription options
- + Made in an optics lab; 1-year warranty
The trade-offs.
- + Established biohacking eyewear brand (formerly BLUblox) with a clear daytime/nighttime lens split
- + Nighttime amber/red lens blocks blue and green light across ~400-550 nm — the variant with a real circadian rationale
- + Non-prescription, reader and prescription options on the same frame
- + Lab-made lenses with a 1-year warranty
- − Blue-light-glasses evidence is limited/mixed — a 2023 Cochrane review found little or no effect on digital eye strain
- − The "FDA/TGA registered" label is establishment registration, not clearance for any health claim
- − Premium price (~$130 non-prescription) versus budget alternatives
- − The daytime clear lens does not publish a filtering percentage

Overview
The BON CHARGE Magnum is a large vintage-metal-framed blue-light glass from BON CHARGE — the Australian biohacking brand formerly known as BLUblox. “Magnum” actually spans two products on the same frame: a daytime clear “computer” lens and a nighttime amber/red lens. Which one you want depends entirely on the job, and the honest framing below matters more than any spec.
Daytime vs nighttime — pick the right lens
- Nighttime amber/red lens: designed for the 2-3 hours before bed, stated to block blue and green light across ~400-550 nm. This is the version with a plausible mechanism: cutting evening short-wavelength light may help your circadian timing.
- Daytime clear “computer” lens: marketed for screen use under artificial light. BON CHARGE doesn’t publish a filtering percentage for it, and — see below — the evidence that clear blue-light lenses reduce eye strain is weak.
If your goal is evening wind-down, the amber/red lens is the one to buy. If you’re buying the clear lens to “fix” screen eye strain, set expectations low.
The evidence, honestly
We won’t repeat claims that these glasses boost melatonin, regulate your circadian rhythm, or improve sleep — none of that is established for this specific product. A 2023 Cochrane review of 17 randomized trials found blue-light-filtering lenses likely make little or no difference to digital eye strain, and the American Academy of Ophthalmology doesn’t recommend them for that purpose. The evening-circadian use has a mechanism but only limited, mixed clinical support — and habits like dimming screens and getting morning daylight likely matter more than any lens.
These are eyewear, not a medical device. BON CHARGE’s “FDA registered / TGA registered” language refers to establishment registration, not clearance to treat or prevent anything.
Price
Roughly $129.99 non-prescription, rising to $210-360 for reader and prescription versions. That’s premium for blue-light glasses; budget brands cost far less, though BON CHARGE’s amber/red night lenses block more than most clear “computer” lenses.
Verdict: Not yet tested
We haven’t bench-measured the Magnum’s lens transmission, so no recommendation yet. As a well-made pair of evening amber/red glasses from a known brand, it’s a reasonable low-risk circadian aid if you want one. As a daytime eye-strain fix, the evidence doesn’t support the spend. Buy the night lens for the wind-down ritual, not for a promised sleep upgrade.
How we’ll assess it
If we test it, we’ll measure lens transmission across the visible spectrum to verify the blocking claims, and compare the night lens against amber/red competitors. See our methodology.
