What do vented goggles protect the eyes from?

Vented goggles are primarily designed to protect the eyes from heat and splashes. The vented design allows for airflow, which helps to prevent fogging of the lenses while maintaining protection against direct exposure to heat, liquids, and possible splashes from work activities, particularly in environments where fluids are handled or heated. This design is crucial for maintaining visibility and comfort, as well as ensuring safety by providing a barrier against potentially harmful substances that could cause eye injury.

Large flying objects, on the other hand, are typically addressed by goggles that have a solid shatter-resistant construction, but the main purpose of vented goggles is not specifically to guard against projectiles. Therefore, while these goggles can offer some protection from debris, it is not their primary function. Instead, their role in shielding eyes from heat and splashes is what makes them valuable in various working conditions, particularly in laboratory or industrial settings.
