Which of the following is a correct eye-protection requirement for fiber optics?

• A. UV tinted lenses
• B. Side shields
• C. Both UV tinted lenses and side shields
• D. No eye protection required

Answer: (B)

Eye protection for fiber optics focuses on guarding against laser light that could reach the eyes, including light that can come from the side due to reflections. Side shields on safety glasses help block those off-axis rays, reducing the chance of retinal exposure when handling fiber ends, connectors, or during inspection and splicing. UV tinted lenses aren’t the standard protection because many fiber-optic systems operate at infrared wavelengths, and a UV tint won’t provide the necessary attenuation. Saying no eye protection is required ignores the real risk of laser exposure. In practice, wear laser-rated eyewear matched to the specific wavelength in use, and make sure it includes side shields.
