"During the average shift (as if there was one), officers can be exposed to spills and splashes, long days in sunlight, projectile objects and people who simply don't cover their mouth when they cough. The potential for exposure to caustic solids and liquids is enormous, and eyes can even be a portal to common diseases like SARS and measles. Research also suggests that ultraviolet (UV) exposure can cause painful eye injuries and contribute to cataract formation and other long-term injuries.
Tactical eyewear creates a protective barrier to these harmful elements. Most people will don glasses when using machinery or working around chemicals. It is only logical that eye protection should be standard issue for law enforcement officers, as well."
