Od6 vs Od7 Laser Safety Glasses: Which One Should You Buy?

od6 vs od7 laser safety glasses: what the ratings mean

OD stands for optical density, and a higher number means the lens attenuates more of the rated wavelengths. That rating only holds inside the wavelength band the listing states, so an OD7 pair rated for one band does not protect at wavelengths outside it. The listings here split into two OD6 pairs and two OD7 pairs, and the bands matter more than the OD number alone.

Protection bands

The OD6 side covers two different band pairs. The JILERWEAR goggles state OD6+ at 180-420nm and 740-1100nm, naming 405nm, 445nm, 450nm, 473nm, 808nm, 980nm and 1064nm lasers. The Hgnova goggles state OD6+ at 900-1100nm and OD5+ at 200-455nm, so the ultraviolet band carries a lower rating than the infrared band. The OD7 side also splits: the MCWlaser glasses state OD7+ at 190-540nm, covering ultraviolet, blue and green wavelengths including 355nm, 405nm, 445nm, 450nm and 532nm, while the JustHot glasses state OD7+ at 800-1100nm for infrared work. No single pair here covers every band, so match the band to your laser first.

Visible light and fit

Visible light transmission decides how bright the view stays through the lens. The MCWlaser glasses state 50% visible light transmission, while the Hgnova and JustHot pairs each state 29%. The JILERWEAR listing states no visible light transmission, so that pair leaves it unclear. For fit, the JILERWEAR goggles and the MCWlaser glasses both state a fit over prescription glasses, with adjustable temples on the JILERWEAR pair and an adjustable non-slip strap on the MCWlaser pair. The JustHot pair states wrap-around side shields with eyebrow protection, and the Hgnova pair states an ultra-light frame in One Size.

Certifications and warranty

All four listings state a certification of some kind. The JILERWEAR goggles state CE PPE certification EN207:2017, the MCWlaser glasses state CE EN 207:2017, and the JustHot glasses state CE EN207 plus FDA standards, with DIR LB5 at 800-1100nm and IR LB7 at 1000-1090nm. The Hgnova goggles state DIR LB4 at 316-455nm and DIR LB5 at 900-1100nm, so the certified ultraviolet range starts at 316nm even though the stated OD5+ band starts at 200nm. On warranty, the Hgnova listing states 1 year, the JILERWEAR and JustHot listings state 30 days each, and the MCWlaser listing states no warranty term.

Choose the OD6 side if

• Your laser runs at 1064nm, which the JILERWEAR and Hgnova listings both cover.
• You want the 1 year warranty stated on the Hgnova listing.
• You want a wraparound fit over prescription glasses, as the JILERWEAR listing states.

Choose the OD7 side if

• You work with blue, green or ultraviolet wavelengths in the 190-540nm band the MCWlaser listing states.
• You work with infrared lasers in the 800-1100nm band the JustHot listing states.
• You want the 50% visible light transmission stated on the MCWlaser listing.

Project Match

• Blue diode engraving and green laser marking: the MCWlaser pair, with 190-540nm OD7+ coverage.
• Infrared welding: the JustHot pair at 800-1100nm, which names welding and cutting, or the Hgnova pair at 900-1100nm, which names welding.
• YAG work at 1064nm: the JILERWEAR pair or the Hgnova pair, both stating 1064nm coverage.
• Work over prescription glasses: the JILERWEAR pair or the MCWlaser pair, both stating an over-glasses fit.
• Ultraviolet work: the MCWlaser pair at 190-540nm, or the Hgnova pair at 200-455nm OD5+.

FAQ: lasers and CNC

Is OD7 always better than OD6?

Not on its own. OD7 means stronger attenuation at the wavelengths the listing rates, but a pair only protects at the wavelengths it states. An OD7 pair rated 190-540nm does not cover a 1064nm fiber laser, while an OD6 pair rated 900-1100nm does. Match the pair to your laser’s wavelength first, then compare OD within that band.

Can I wear laser glasses over prescription glasses?

Two listings here state it: the JILERWEAR goggles and the MCWlaser glasses both state a fit over prescription glasses. The Hgnova and JustHot listings do not state an over-glasses fit, so check before you buy if you wear prescription lenses.

What wavelength range do I need?

It depends on your laser. For work at 1064nm, the JILERWEAR, Hgnova and JustHot listings state bands that include that wavelength. Blue, green and ultraviolet work falls in the 190-540nm band the MCWlaser listing states. Check your laser’s stated wavelength, then pick a pair whose stated band includes it.

Do these glasses work for diode and fiber lasers?

It depends on the pair. The MCWlaser listing names diode laser systems, and the JILERWEAR and JustHot listings name fiber lasers or YAG work. The Hgnova listing names welding and marking work without naming a fiber laser or YAG system. No single pair here covers every wavelength, so match the band to the machine.

How do I check the certification?

Look for the OD rating and wavelength band on the listing, plus the certification it names. The pairs here state CE EN207:2017, DIR LB ratings or FDA standards, depending on the listing. If a listing states no OD and no band, it is not rated protection.
