I. Basic Definitions & Protection
Mechanisms
Medical isolation face shields are
typically made of transparent polycarbonate or PET materials, covering the full
face or upper facial area. They create a physical barrier against droplets,
blood, and bodily fluids through:
• Splash-proof design: Curved
extension structure intercepts multi-angle splashes
• Ventilation balance: Top vents
maintain protection and wearer comfort
• Anti-fog treatment: Dual-sided
coatings prevent visual obstruction
Goggles feature sealed frames and elastic
headbands for ocular protection, with key characteristics:
• Side protection: Wraparound
design seals canthal gaps
• Impact resistance: Complies
with EN166/ANSI Z87.1 standards
• Adjustable nose pads: Ensure
airtight fit for various facial structures
