I. Core Protection Principle of Bulletproof Face Shields

1. Hard Impact Resistance: High-strength transparent bulletproof materials are used as the core panel to directly resist low-speed bullets, shrapnel, gravel and chemical liquid intrusion, avoiding facial soft tissue damage and eye injuries.
2. Transparent Visibility: The light transmittance of the panel is ≥85%, meeting the requirements for visual clarity in tactical operations. Some high-end models are equipped with anti-fog coatings, which can adapt to harsh environments such as alpine and humid conditions, ensuring all-weather combat capability.
3. Lightweight Bearing: The face shield is connected to the bulletproof helmet through a quick-release bracket, with a weight controlled between 0.5-1.2kg, which does not add extra head load. It also supports quick disassembly to meet the switching needs of different mission scenarios.

II. Core Classifications and Applicable Scenarios of Bulletproof Face Shields

1. Anti-Shrapnel Face Shield

1. The protection level reaches NIJ Level Ⅰ/ⅡA, with polycarbonate (PC) as the core material, which can resist low-speed impactors such as pistol bullet shrapnel, glass bottle fragments and stones. With a weight of only 0.5-0.8kg and high light transmittance, it is suitable for low-to-medium risk scenarios such as daily patrols and riot control, and is a basic protective equipment for grassroots law enforcement personnel.
2. Bulletproof and Stab-Resistant Face Shield

1. The protection level reaches NIJ Level ⅢA, adopting a composite panel of polycarbonate + aramid fiber, with both bulletproof and stab-resistant performance, which can resist direct pistol bullet fire at close range and sharp instrument puncture. Weighing 0.8-1.0kg and equipped with anti-scratch coating, it is suitable for medium-to-high risk scenarios such as street conflicts and arrest operations, and is ideal for special police and security forces.
2. Special Tactical Face Shield

1. The protection level can reach NIJ Level Ⅲ, with a composite layer of alumina ceramic + transparent bulletproof glass as the core material, which can resist rifle bullet shrapnel and high-speed flying debris impact. It integrates functional modules such as tactical light interface, communication headphone bracket and gas mask adapter. Some models support night vision device adaptation, weighing 1.0-1.2kg, suitable for ultra-high risk scenarios such as counter-terrorism assaults and hostage rescue, and is a core equipment for special forces.

IV. Global Mainstream Certification Standards for Bulletproof Face Shields

1. North American NIJ Standard: Tested according to NIJ 0106.01 standard, divided into multiple levels such as Ⅰ, ⅡA, Ⅱ, ⅢA, Ⅲ according to protection capabilities, clearly specifying the bullet types, speeds and impact angles resisted by each level, and is the authoritative basis for military and police procurement in North America.
2. European EN Standard: The core is EN 166 standard (eye protection) and EN 1522 standard (bulletproof performance), focusing on the light transmittance, anti-fog property and environmental adaptability of the face shield. It must be marked with CE label to enter the European market.
3. Middle East SABER Certification: Mandatory in Saudi Arabia, UAE and other countries. It is necessary to complete Product Conformity Certification (PC) and Shipment Conformity Certification (SC). The label must be marked with Arabic protection level, production date and compatible helmet model, suitable for the high-temperature and sandy use environment in the Middle East.

V. Core Points for Selecting Bulletproof Face Shields

1. Match Protection Level: Choose anti-shrapnel face shields for low-risk scenarios, bulletproof and stab-resistant face shields for medium-to-high risk scenarios, and special tactical face shields for ultra-high risk scenarios to avoid excessive or insufficient protection.
2. Adapt to Helmet Model: Select face shields compatible with the interface of existing bulletproof helmets (such as ARC rails, MOLLE systems) to ensure firm installation and convenient disassembly.
3. Focus on Environmental Adaptability: Choose models with anti-fog coatings for alpine and humid areas; choose face shields with sand and dust proof design for desert areas to ensure clear vision.
4. Recognize Compliant Certifications: Exports need to match target market certifications (NIJ/EN/SABER), and domestic procurement must comply with relevant standards of the public security department to avoid failure to be equipped due to lack of certifications.
