Lightweight black imported PC material frame, unique curved surface design, comfortable wearing, impact resistance, lighter and durable.
With flanking and eyebrow protection, it can fully protect the eye from laser damage.
Large-sized lenses can be set over myopia.The temple has round holes, which comes with free adjustment silicone lanyard.
The lens uses imported optical material, hardened and strengthened, anti-impact, anti-scratch, explosion-proof, alcohol-resistant, hot-water resistant.
Q: How many types of protective glasses are there? What is the difference？
A: Two types in total, absorption and reflection type.
Absorptive goggle: The laser absorber was added to lens material
Reflective goggle: The surface of the lens was covered with a reflective film.
Q: How often to replace the protective goggle?
A: Absorptive goggle: Normally replace in 1-3 years, depending on actual use.
Reflective goggle: Normally replace in 1-2 years. If the reflective film is scratched, it can no longer be used and needs to be replaced.
Q: What is the optical density?
A: Used to indicate the percentage of laser light of a specific wavelength that can pass. through the laser goggles.
For Example:
OD1+: This means that 10% of the laser light of a certain wavelength can pass through the laser goggles.
The same principle is as follows.
OD2+: 1% ; OD3+: 0.1%; OD4+: 0.01%; OD5+: 0.001%; OD6+: 0.0001%; OD7+: 0.00001%
Q: What is the visible light transmittance?
A: Used to indicate the percentage of visible light that passes through the laser goggles. The higher VLT%, the brighter the lens and the clearer the field of vision.
For low-power (≤1mw) lasers, protective measures should be taken, otherwise it will cause cumulative laser damage to the eyes; for lasers with laser output powers greater than 1mw and less than 0.5w, direct laser beams are only allowed to wear laser protective glasses, otherwise In the blinking reflection time of about 0.25s, its output laser can cause eye damage; for lasers with power> 0.5w, it is the most harmful to the eyes. Whether it is directly looking at the light beam or irradiated by its reflected light can cause eye damage. Strict protective measures must be taken for this type of laser. No person wearing laser protective glasses is allowed to operate such lasers.
