Which of the following is a passive laser protective countermeasure?

• A. Take Cover
• B. NVGDS
• C. Protective Goggles
• D. Squinting

Answer: (C)

The main idea here is using equipment that reduces laser energy reaching the eyes without needing power or active action. Protective eyewear does this by filtering the laser wavelengths and attenuating the light before it enters the eye. Laser protective goggles are designed with filters that absorb or reflect the specific wavelengths used by lasers, lowering the energy that would otherwise reach the retina. Because you simply wear them, they provide immediate, passive protection. Other options don’t fit as well. Taking cover is a defensive move that can help, but it’s not a protective device and its effectiveness against lasers isn’t guaranteed. NVGDS isn’t a protective eyewear item and doesn’t serve as eye protection against laser energy. Squinting attempts to limit light but is unreliable and can still allow dangerous energy to reach the eye.
