You want the best protection for peace of mind when working in daily environments with potential viral exposure.
Eye exposure transmission- Studies has shown the eye is part of mucus membrane and susceptible to airborne transmission from viruses.
Proper fit- Many safety goggles do not provide a tight fit which allows environmental air into eye space. People wearing eye glasses are subject to wearing goggles over them, creating fit and comfort issue. Oversized goggles create a fit issue with respirator masks. Multiple PPE wear causes head gear and strap crossovers.
Sealed goggle- Are not recommended by the CDC. They may create fogging issues over prolong use and intraocular pressure observed in swimming goggles. Intraocular pressure is a risk factor in progression of glaucoma.
Indirect vent goggles- Provides vents into eye space but allows unfiltered environmental air exposure. Face masks can exhale hot air to fog up direct and indirect vented goggles or open eyewear.
Contamination risks- Eyewear without head straps may shift or fall off with physical activity which would lead to exposure or contamination risks.
Comfort issue- Rigid seal materials creates skin discomfort over prolong daily use. A full face mask has optimal protection although uncomfortable for prolong use daily (hot, heavy, hard communication)
