Infrared is invisible. The danger to the eyes is not.

Infrared radiation remains invisible to the human eye, yet it poses a significant risk in many work environments. Reliable eye protection must block these dangers without restricting the view of the work environment, displays, or warning signals. The Zhi IR 1.7 safety glasses from UNICO Graber close precisely this gap in occupational safety.

What is infrared radiation and what are the dangers?

Infrared radiation (IR radiation) is part of optical radiation and lies outside the spectrum visible to humans. It is primarily perceived as heat radiation and occurs wherever high temperatures, glowing materials, or intense heat sources are used.

Depending on the intensity and duration of exposure, IR radiation can permanently damage the anterior eye areas as well as deeper structures. Since the natural blink reflex often does not trigger with invisible radiation, the risk is frequently underestimated without professional assessment.

The problem with conventional IR safety glasses

Classic infrared protective filters effectively absorb radiation, but usually lead to a strong darkening of the field of vision. In addition, they cause significant color distortion, which can be critical in daily work.

In many industrial and laboratory areas, signal colors such as red, yellow, and green are essential for recognizing operating statuses or warning messages. If these colors are distorted by the filter, orientation decreases and the risk of accidents increases.

The strengths of the Zhi IR 1.7

The Zhi IR 1.7 was specially developed for the low-level infrared range. Its tested protective lens reliably filters dangerous infrared radiation, while natural color perception is largely maintained.

The scratch-resistant polycarbonate protective lens is certified according to EN 171 with protection level 4C-1.7. It meets the requirements for mechanical strength according to EN 166 F and additionally offers 100% UV protection up to 400 nanometers.

Wearing comfort for everyday work

Safety glasses only unfold their effect if they are worn continuously. With a weight of only around 30 grams and a sporty design, the Zhi IR 1.7 offers maximum comfort.

A soft nose pad prevents pressure points, while the adjustable TPU temples allow for individual adaptation to the head shape. This ensures a secure and comfortable fit even during long periods of use.

The most important features at a glance

• Low-Level IR Protection: Specifically developed for workplaces with lower infrared exposure.
• Certified Standards: IR protection level 4C-1.7 according to EN 171 and mechanical strength according to EN 166 F.
• High Color Fidelity: Reliable recognition of signal colors and visual checks.
• Comprehensive Glare Protection: Integrated 100% UV protection up to 400 nm.
• Robust Material: Scratch-resistant protective lens made of highly durable polycarbonate.
• Ergonomic Design: Lightweight at 30 grams, soft nose pad, and malleable temple ends.

Application with private infrared and therapy lamps

In the private sector, infrared and heat lamps are increasingly used for muscle relaxation or health care. When applied to the face, the eyes are often close to the radiation source, and closed eyelids do not provide sufficient protection.

If the device manufacturer prescribes protection level 4C-1.7, the Zhi IR 1.7 is also a comfortable solution here. Important: For pure red light or LED devices, different requirements apply. The manufacturer's specifications of the respective lamp are always decisive.

Typical areas of application

• Metal and Steel Processing: Control work with moderate heat and radiation exposure.
• Glass Processing: Precise optics during thermal process steps.
• Laboratory & Electronics: Work on technical test benches and under infrared light.
• Medicine & Therapy: Protection of personnel during therapeutic IR applications.
• Private Use: Application with infrared lamps according to manufacturer's specifications.

The correct risk assessment as a basis

Every radiation source requires an exact matching of eye protection. The Zhi IR 1.7 is not a substitute for welder's safety glasses for high intensity, but covers the weaker IR range. Radiation intensity, exposure duration, and working distance are crucial.

Conclusion: Optimal protection without loss of perception

The Zhi IR 1.7 combines reliable infrared protection according to EN 171 with high color fidelity and excellent wearing comfort. UNICO Graber will gladly assist you in selecting the appropriate safety glasses based on your individual risk assessment. Contact our experts for a personal consultation.
