The Centers for Disease Control and Prevention (CDC) recommends eye protection for a variety of potential exposure settings where workers may be at risk of acquiring infectious diseases via ocular exposure. This document provides background information and specific details on eye protection that can be used to supplement eye protection recommendations provided in current CDC infection control guidance documents. It is intended to familiarize workers with the various types of eye protection available, their characteristics, and their applicable use. Workers should understand that regular prescription eyeglasses and contact lenses are not considered eye protection. ---CONTINUED---

4. Eye Protection/Face Shield
4.1 Eye protectors (face shields or goggles) should be worn when in direct face to  face contact with a person suspected or confirmed to have pandemic influenza or their environment to protect mucous membranes of the eyes from direct transmission of the virus onto the eye or from indirect transmission from a contaminated hand touching the eye.
4.2 If goggles are used, they should fit snuggly (but comfortably) around the eyes.  
4.3 For aerosol-generating procedures (e.g. nebulizer treatments, intubation), a face shield may be worn over goggles to protect exposed areas of the face but should not be worn as a primary form of eye protection for these procedures.
4.4 Clean, disinfect and store re-usable face shields or goggles as recommended by the manufacturer.
4.5 When resources are limited, consider assigning each health care worker needing eye protection one eye protection/face shield, consider postponing non-emergency procedures where the use of eye protection is necessary.
