Selection, Use, and Maintenance of Eye/Face Protection Products

Occupational Eye/Face Hazards

Hazard Type	Typical Harmful Agents	Typical Job Roles
Impact of solid particles	Metal shavings, wood chips, stones	Riveting, assembly, grinding, decoration, weeding
Splash of harmful liquids	Acids, alkalis, organic solvents	Laboratory, chemical handling, transport, disposal
Exposure to harmful light	Ultraviolet (UV) light, laser	Welding
Light intensity	Artificial strong light, sunlight	Outdoor operations
Thermal radiation	Infrared radiation	Welding

Refer to Table 2-2.

Table 2-2 Lens Materials and Performance Note: √ indicates excellent performance; x indicates unqualified.

Protective eyewear lenses must meet the F-level requirement for high-speed particle impact resistance.

F-level: A 6 mm steel ball impacting at 45 m/s (162 km/h) must not cause lens breakage or deformation.

Choose products based on the work environment and usage habits. Refer to Table 2-3.

Table 2-3 Basic Principles for Selecting Eye/Face Protection Products

Function	Product Selection Requirements
Optical performance	High transmittance, accurate diopter, prismatic power; UV filtration, glare reduction, welding compatibility
Physical performance	Impact resistance, high-speed particle resistance
Chemical protection	Corrosion resistance
Coating	Anti-fog coating, anti-scratch coating
Comfort	Ergonomic fit, minimal pressure on nose, ears, or temples

Select eyewear based on face shape and usage habits. Refer to Table 2-4.

Table 2-4 Comfort Requirements

Comfortable Eyewear	Uncomfortable Eyewear
Designed for Asian facial features (Asian version);	Designed for Western facial features (Western version);
Flexible rubber nose pads to evenly distribute pressure;	Nose pads press on nasal wings, causing pain over time;
Soft rubber temple pads; headband size matches user’s head shape;	Temple pressure causes ear/head pain;
No dizziness or vision impairment during prolonged use.	Rapid diopter changes, blurred vision, dizziness, or headaches during prolonged use.

Refer to Table 2-5.

Table 2-5 Selecting Products by Hazard Type/Scope

Hazard Type/Scope	Recommended Products	Industry Applications
General particle impact	Safety goggles	Automotive, electronics, shipbuilding
Dust, mist, or liquid splash	Goggles	Petrochemical, logistics, woodworking, plastics
High-impact or large-area splash	Face shields	Forestry, smelting, mining
Welding light	Welding goggles or face shields	Welding, foundries, heavy machinery

Refer to Table 2-6.

Table 2-6 Lens Color Selection by Harmful Light

Harmful Light Type	Suitable Lens	Visible Light Transmittance (VLT)	Absorbed Radiation	Application Environment	Typical Roles
UV, no other harmful light	Clear	92%	99.9% UV below 385 nm	Indoor/outdoor low-light	Riveting, assembly, light grinding
Low light + UV	Yellow	87%	99.9% UV below 400 nm	Low-light with high contrast	Forestry, QC, labs, shooting
Artificial/sunlight + UV	Silver	45%	99.9% UV below 385 nm	Indoor/outdoor glare reduction	Construction, utilities, roofing
Strong sunlight + UV	TSR Grey	22%	99.9% UV below 400 nm	Outdoor glare reduction	Aviation, transportation, roofing
Infrared + UV + strong light	Welding (IR3/IR5)	17% (IR3), 2% (IR5)	99.9% UV below 385 nm; 88% IR (780–1400 nm)	Welding environments	Welding, foundries, glass production

Refer to Table 2-7.

Table 2-7 Coating Selection by Protection Needs

Protection Need	Suitable Coating	Function
High abrasion, low fog risk	Anti-scratch coating	Enhances durability and clarity
High fog risk	Anti-fog coating	Prevents fogging for clear vision

Clean lenses with specialized lens cleaner and wipe with a microfiber cloth. Avoid hot water.
Store eyewear in a clean case after use.
Replace scratched lenses promptly to avoid vision impairment.
