I. Core Protection Principles of Tactical Goggles

1. High-Strength Impact-Resistant Core Layer

1. The lenses are integrally injection-molded with super-tough polycarbonate (PC), whose impact resistance is 250 times that of ordinary glass. It can resist the direct impact of hard objects such as 9mm pistol bullet shrapnel, high-speed steel balls and gravel, with an impact protection level up to EN 166 Class F. When impacted, it only produces tough deformation without cracking, avoiding secondary eye injury from lens fragments. The frame is made of high-strength TR90 elastic material, which can withstand severe collisions and bends, is not easy to break when dropped or impacted, and fits the facial contour without displacement or falling off during intense tactical movements.
2. Multi-Coating All-Scenario Optical Protection

1. The lens surface adopts a vacuum coating process, superimposed with five protective coatings: anti-fog, anti-scratch, anti-ultraviolet, anti-glare and anti-blue light, adapting to the visual needs of different environments. The anti-fog coating solves the problem of lens fogging in high temperature, humidity and large temperature difference scenarios; the anti-scratch coating improves lens wear resistance and prolongs service life; the anti-ultraviolet/anti-glare coating resists direct strong light in deserts and snowfields to avoid visual vertigo; the anti-blue light coating is suitable for night tactical lights and electronic equipment usage scenarios to protect eyesight.
2. Ergonomic Tactical Adaptive Design

1. Adopting a panoramic wide-view lens design, the field of view is 40% larger than that of ordinary goggles with no optical distortion, ensuring the accuracy of close-range aiming and long-distance observation; the temple is equipped with adjustable telescopic buckles and anti-slip silicone pads, adapting to different head shapes and bulletproof helmet wearing needs without squeezing the head; the part of the frame in contact with the face is equipped with a soft sponge sealing pad, which fits the eye socket contour, effectively preventing sand, dust and splashes from entering, and improving wearing comfort while reducing the sense of oppression during long-time wearing.

II. Core Classifications and Applicable Scenarios of Tactical Goggles

1. General Tactical Goggles

1. Basic core protective goggles, equipped with transparent anti-fog and anti-scratch lenses, the frame is made of lightweight TR90 material, with a single pair weight ≤30g and a protection level up to EN 166 Class F. Suitable for conventional scenarios such as daily patrols, tactical training and urban law enforcement. Its advantages are light weight, comfort and wide field of view. It can be worn alone or in conjunction with ordinary police helmets to meet basic eye protection needs.
2. Outdoor All-Terrain Tactical Goggles

1. Designed for complex outdoor terrains such as mountains, jungles and deserts, equipped with replaceable transparent/tea/gray three-color lenses. Tea/gray lenses resist strong glare, and transparent lenses are suitable for low light and cloudy days; the frame sealing performance is upgraded, and the thickened sponge sandproof pad effectively prevents sand and gravel from entering. Suitable for missions such as border patrols, field reconnaissance and desert stability maintenance, and is suitable for equipping border troops and field combat units.
2. Riot and Chemical-Resistant Tactical Goggles

1. Reinforced protective goggles, the lenses are made of PC + aramid fiber composite material, with a protection level up to EN 166 Class B, which can resist machete slashes, chemical liquid splashes and Molotov cocktail spark impacts; the frame is fully sealed with a chemical-resistant rubber sealing pad to effectively block the penetration of acidic and alkaline chemicals. Suitable for high-risk scenarios such as riot control, chemical emergency disposal and anti-riot stability maintenance, it is the core equipment of anti-riot police and emergency disposal units.
2. Night Vision Compatible Tactical Goggles

1. Designed for night tactical missions, equipped with high-transmittance infrared lenses that can transmit the infrared band of night vision goggles without affecting the use effect of night vision goggles, thermal imagers and other equipment; the lenses are superimposed with an anti-blue light coating to resist blue light stimulation from tactical lights and laser pointers; the frame adopts a low-profile design, seamlessly adapting to bulletproof helmets and tactical face shields to form a "helmet + face shield + goggles" full head protection system. Suitable for low-light scenarios such as night counter-terrorism, urban warfare clearance and underwater reconnaissance, and is suitable for special police and special forces to perform night missions.

III. Core Materials of Tactical Goggles: Technical Balance Between Protection and Optical Performance

IV. Global Mainstream Certification Standards for Tactical Goggles

1. European EN 166 Standard

1. The world's most authoritative general standard for tactical goggles, divided into multiple levels such as A, B and F according to impact resistance and shrapnel resistance performance. It clearly specifies core indicators such as lens light transmittance, impact resistance, scratch resistance and optical distortion, and simultaneously tests the protection stability in high and low temperature (-40℃~+70℃), humidity and sand dust environments. Products must be marked with a CE label to enter the European and EU member states markets.
2. North American ANSI Z87.1+ Standard

1. A mandatory certification standard for military and police protective equipment in North America. On the basis of basic impact and puncture resistance tests, it adds high-speed particle impact test and chemical splash protection test, requiring the lens to withstand steel ball impact at 190 meters per second without cracking. At the same time, it has strict requirements on the durability of the lens coating and the structural stability of the frame, which is the core basis for North American military and police procurement.
2. Middle East SABER Certification

1. Mandatory in Saudi Arabia, the United Arab Emirates, Qatar and other Middle Eastern countries. It is necessary to complete Product Conformity Certification (PC) and Shipment Conformity Certification (SC). The product label must be marked with Arabic protection level, high temperature resistance parameters and lens coating functions, adapting to the high temperature, strong ultraviolet and dusty use environment of the Middle East desert, ensuring that the lens anti-fog and anti-glare coatings do not fall off under extreme high temperature and the protection performance is stable.

V. Core Points for Selecting Tactical Goggles

1. Match the Protection Needs of the Mission Scenario

1. Choose general pure PC lens goggles (EN 166 Class F) for regular patrols and training; choose outdoor all-terrain replaceable lens goggles for outdoor mountain and desert missions; choose riot and chemical-resistant goggles (EN 166 Class B) with PC + aramid fiber composite lenses for anti-riot and chemical operations; prioritize night vision compatible goggles with high-transmittance infrared lenses for night missions to avoid eye injuries due to insufficient protection.
2. Prioritize Optical Performance and Field of View

1. Choose lenses with light transmittance ≥92%, no optical distortion and panoramic wide field of view to ensure the accuracy of aiming, observation and tactical judgment; avoid choosing styles with overly thick lenses and narrow field of view to prevent affecting tactical movements and field of view.
2. Balance Tactical Compatibility and Wearing Comfort

1. Confirm that the goggles can be seamlessly compatible with existing bulletproof helmets and tactical face shields, with adjustable temples and good frame sealing performance; prioritize styles with TR90 elastic material frames and soft sponge pads at the facial contact points to reduce the sense of oppression and skin abrasion during long-time wearing, and ensure that the equipment does not displace during intense tactical movements.
2. Pay Attention to the Practicality and Durability of Lens Coatings

1. Choose coating combinations according to the mission environment: focus on super anti-fog coating in high temperature and humid areas; anti-glare + anti-ultraviolet coating in deserts and snowfields; anti-blue light + high-transmittance infrared coating for night missions; at the same time, check the coating adhesion to avoid products with easy-to-peel and poor wear-resistant coatings, and prolong the service life of the equipment.
2. Recognize the Compliance Certification of the Target Market

1. Export products must strictly match the target market certification (EN 166/ANSI Z87.1+/SABER), and domestic procurement must comply with the public security department's industry standard for Police Protective Goggles, to ensure that the product has passed authoritative agency testing and meets both protection and optical performance standards.
