A maker setting up a diode laser needs glasses that match the machine wavelength, not just any dark lens. This comparison covers blue vs green laser safety glasses through two blue-side FreeMascot examples, and says plainly where the green side stays unclear because no green-side listing is listed here.

Verdict: pick blue-side glasses for blue diode laser work at 405nm, 445nm or 450nm, where both examples state OD 6+ and EN207 approval. Pick green-side glasses only when the listing states a wavelength range that matches a green laser; neither listing here states a green range, so this comparison cannot confirm a green figure from these listings.

| FreeMascot Frame 5 | 190nm-490nm | OD 6+ | 55% | 6 Months |

Specifications are manufacturer rated, as published on each listing and collected 29 October 2026. Both examples here are blue-side listings, so the green side is judged on what is missing, not on a stated figure.
Blue vs green laser safety glasses: wavelength coverage
Both FreeMascot listings state a 190nm to 490nm wavelength range with OD 6+ at 405nm, 445nm and 450nm, and both list compatibility with 275nm, 365nm, 405nm, 445nm and 450nm laser light. That range covers the blue diode wavelengths named on the listings, but the title on each listing also names 473nm, which appears in neither the OD 6+ statement nor the compatible list. Treat 473nm as unclear on these listings rather than covered. No green wavelength range is stated on either listing, so a green laser needs a different listing with its own stated range.
OD figure and certification
Both listings state OD 6+ and EN207 approval, which is the core of their safety case: eyewear protects only when the listing states an OD figure and a wavelength range that matches the machine. The two listings differ in how the approval is printed. Frame 5 prints a garbled line mixing EN207 editions 1998 and 2002, while Frame 4 prints EN207 approval to 2017 plainly. The OD figure itself is identical on both, so certification does not separate them on protection.
Visible light and comfort
Both listings state 55% visible light transmittance, so the view through the lens should match between the two frames. Both use a fit-over frame in a black frame color, though neither listing describes fit beyond the frame name and a size of 5.5*18cm. Neither listing states padding details, so comfort beyond the fit-over style is left unclear.
Fit and frame
The two listings share the same model code TUB-2, the same size, the same color and the same stated range; they differ in frame number, stated warranty and the printed EN207 edition. Neither listing gives a fit guide or a range of head sizes, so fit has to be judged from the stated size alone. If the frame number matters to a buyer, it is a further reason to pick one over the other, beside the stated warranty.
Warranty and support
Frame 5 states a 6 Months warranty in the spec table, while Frame 4 states no warranty term at all. That warranty difference is why Frame 5 ranks above Frame 4 here; the range, OD figure, visible light figure and frame style match, and only the printed EN207 edition and the frame number differ besides the warranty. Neither listing states a support channel or a replacement policy, so warranty is the only support figure available.
Choose blue laser safety glasses if
- You run a blue diode laser at 405nm, 445nm or 450nm.
- You want OD 6+ with EN207 approval and 55% visible light transmittance.
- You want a fit-over frame, with Frame 5 adding a stated 6 Months warranty.
Choose green laser safety glasses if
- You run a green laser and need glasses matched to that machine.
- You find a listing that states OD and a wavelength range covering the green laser.
- You do not rely on a blue-side listing for green work, since neither listing here states a green range.
Eyewear protects only when the listing states an OD figure and a wavelength range that matches the machine. Tinted shields without a stated OD figure are not protection. Match the stated range to the machine before buying, and never assume a blue-side pair covers a green laser.
Project Match
- Blue diode laser work at 405nm, 445nm or 450nm: both FreeMascot examples state OD 6+ at those wavelengths.
- Work with light at 275nm or 365nm: both listings name those wavelengths as compatible.
- Green laser work: Not stated in these listings; no green-side example is listed here.
- Materials and project types beyond wavelength work: Not stated in these listings.
FAQ: lasers and CNC
Do blue laser glasses work for green lasers?
Not from what these listings state. Both examples state OD 6+ at 405nm, 445nm and 450nm, and neither states a green range. Match the listing range to the machine before buying.
What does OD 6+ mean?
OD 6+ is the optical density figure both listings state at 405nm, 445nm and 450nm, within a stated 190nm to 490nm wavelength range. Check that the stated range covers the machine wavelength, since the figure alone does not name the machine.
What is visible light transmittance?
Both listings state 55% visible light transmittance. That figure describes how much visible light passes through the lens, as stated on the listing.
Can these glasses fit over prescription glasses?
Both listings describe a fit-over frame. The listings do not state prescription compatibility beyond the fit-over frame description, so check the stated frame size of 5.5*18cm.
Which FreeMascot frame should I pick?
Frame 5 states a 6 Months warranty and EN207 approval across 1998 and 2002 editions, while Frame 4 states EN207 approval to 2017 and no warranty term. Pick Frame 5 for the stated warranty term; otherwise the two listings state the same range, OD figure and visible light figure.
