In healthcare, the eyes are often overlooked. Gloves protect the hands. Masks protect the nose and mouth. Gowns protect clothing and skin. But the eyes are also mucous membranes, which means they can become an entry point for infectious agents.
The CDC states that infectious agents can reach the eyes through splashes, respiratory droplets, or contaminated fingers, and that regular prescription glasses and contact lenses do not provide enough protection.
That is why eye protection in healthcare is not optional when exposure risk is present. It is a core part of infection control, worker safety, and patient safety.
For healthcare teams reviewing their full PPE program, this guide on essential PPE for healthcare professionals is a useful starting point.
Goggles vs Face Shields: What’s the Difference?
Goggles and face shields are both used for eye and face protection, but they are not always interchangeable.
Goggles
Goggles are designed to fit closely around the eyes. They help protect against splashes, droplets, sprays, and certain airborne particles depending on design.
Goggles are commonly used when:
- There is a direct splash risk
- Eye protection needs to fit close to the face
- A face shield alone may leave gaps
- Staff are working near blood, body fluids, or chemical hazards
Face Shields
Face shields cover a larger area of the face, typically from the forehead down past the chin. They help protect the eyes, nose, and mouth area from splashes, sprays, and droplets.
Face shields are useful during:
- Dental procedures
- Suctioning
- Wound irrigation
- Specimen handling
- Cleaning contaminated equipment
- Procedures with splash or spray risk
A face shield provides broad facial coverage, but it does not always replace goggles. A clinical review notes that face shields provide barrier protection for the facial area and related mucous membranes, but they also have limitations compared with other forms of eye protection.

When Are Goggles and Face Shields Required?
1. During Procedures With Splash or Spray Risk
Eye protection is required when healthcare workers may be exposed to splashes or sprays of blood, body fluids, secretions, or excretions.
The Public Health Agency of Canada recommends facial protection, including masks and eye protection or face shields, during procedures and patient-care activities likely to generate splashes or sprays of blood, body fluids, secretions, or excretions.
Common examples include:
- Suctioning
- Intubation support
- Wound irrigation
- Dental scaling or drilling
- Blood collection with splash risk
- Handling contaminated instruments
- Cleaning bodily fluid spills
2. During Transmission-Based Precautions
In infection control, eye protection is often used with masks, gloves, gowns, or respirators depending on the disease and exposure risk.
CDC Standard Precautions are used for all patient care and rely on risk assessment and appropriate PPE to protect healthcare providers and prevent infection spread from patient to patient.
For higher-risk care, such as suspected respiratory infections or isolation precautions, eye protection may be part of the required PPE bundle.
Facilities focused on reducing contamination risk should also review how PPE helps prevent cross-contamination in labs.
3. During Aerosol-Generating Procedures
Aerosol-generating procedures require extra caution. These may include intubation, bronchoscopy, non-invasive ventilation, open suctioning, or certain dental procedures.
CDC guidance notes that during aerosol-generating procedures for patients with suspected or proven infections transmitted by respiratory aerosols, healthcare workers should wear a fit-tested N95 or higher respirator in addition to gloves, gown, and face/eye protection.
For respiratory protection decisions, this guide on N95 surgical masks can help teams understand where respirators fit into a broader PPE plan.
4. In Dental and Laboratory Settings
Dental and lab environments create unique eye exposure risks.
Dental teams may face splatter from saliva, blood, water spray, and aerosols. Lab staff may face exposure from specimens, chemicals, centrifuges, and contaminated surfaces.
In these settings, eye protection should be selected based on task risk, not convenience. Dental clinics can also review PPE standards for Canadian dental clinics for a more compliance-focused approach.
5. When Handling Chemical Disinfectants
Eye protection is also important outside direct patient care. Staff using hospital-grade disinfectants, chemical cleaners, or sterilization products may need goggles or face shields based on the product’s Safety Data Sheet.
OSHA states that eye and face protection must be provided whenever necessary to protect employees from chemical, environmental, radiological, or mechanical hazards.
For cleaning and infection control programs, this article on hospital-grade disinfectants vs consumer products is a helpful companion resource.
How to Choose the Right Eye Protection
Fit and Coverage
Eye protection should fit securely without leaving major gaps. Staff should be able to move, bend, and work without the goggles or face shield shifting.
Anti-Fog Performance
Fogging reduces visibility and increases the temptation to touch or adjust PPE. Choose anti-fog options when possible, especially for long shifts or procedure-heavy environments.
Compatibility With Other PPE
Eye protection should work with masks, N95 respirators, surgical caps, gowns, and gloves. A poor fit between a respirator and goggles can reduce comfort and compliance.
Disposable vs Reusable
Disposable eye protection may be preferred in high-contamination settings. PHAC states that disposable eye protection or face shields should be worn only once to avoid self-contamination and should not be positioned on the head or around the neck for later use.
Reusable goggles and face shields require cleaning, disinfection, inspection, and storage protocols.
Common Mistakes to Avoid
- Wearing prescription glasses instead of proper eye protection
- Reusing disposable face shields
- Moving eye protection onto the forehead or neck
- Choosing face shields that do not extend below the chin
- Ignoring fogging and comfort issues
- Using damaged or scratched eye protection
- Failing to train staff on donning and doffing
The CDC advises discarding eye protection if it is damaged, cannot fasten securely, or visibility remains obscured after cleaning and disinfection.
Quick Case Example
A dental clinic notices that staff often remove face shields between patients and place them on counters. During an internal audit, the clinic updates its protocol: face shields are stored cleanly, disposable shields are not reused, and goggles are required for higher-splash procedures.
The result is simple but powerful: fewer PPE mistakes, cleaner workflows, and more consistent infection control.
FAQ: Eye Protection in Healthcare
Are face shields required in healthcare?
Face shields are required when there is a risk of splashes, sprays, droplets, or exposure to blood, body fluids, or infectious material.
Are goggles better than face shields?
Not always. Goggles provide closer eye coverage, while face shields protect more of the face. Some tasks may require one or both.
Can prescription glasses replace goggles?
No. Prescription glasses do not provide adequate side and splash protection for healthcare exposure risks.
When should healthcare workers wear both goggles and a face shield?
Both may be used when there is a high splash, spray, or chemical exposure risk, or when facility policy requires added protection.
Should eye protection be disposable or reusable?
Both can be appropriate. Disposable protection is useful for high-contamination settings, while reusable items require proper cleaning, disinfection, and inspection.
Final Thoughts
Eye protection in healthcare is not just about compliance. It is about protecting staff, patients, and the care environment from preventable exposure.
The best approach is practical: assess the task, match PPE to the risk, train staff, inspect equipment, and choose reliable products that support real-world workflows.
