What is the main function of goggles in a phlebotomy setting?

In a phlebotomy setting, the main function of goggles is to protect the eyes from splashes of potentially infectious materials, which includes blood and other bodily fluids. Phlebotomists often work with sharp instruments and may encounter situations where liquids can be expelled or splattered inadvertently. This exposure poses a risk of transmitting infections or pathogens that may be present in those fluids. Therefore, wearing goggles serves as a critical safety measure to prevent contamination and protect the mucous membranes of the eyes from harmful exposure.

While improving vision and enhancing tissue visibility might be beneficial in certain healthcare environments, these are not the primary purpose of goggles during phlebotomy procedures. Additionally, while there may be situations where heat protection is relevant in different contexts within medical settings, it is not a concern that goggles address in phlebotomy tasks. Thus, the correct understanding centers on the protective role of goggles against infectious exposure.
