288275 - Miller HDV Clear Replacement Lens for Industrial Face Shields

Technical Overview of the Miller 288275 Replacement Lens

The Miller 288275 is a premium replacement clear lens designed specifically for Miller Industrial Strength Face Shields. This component is engineered to meet the rigorous demands of industrial environments, providing essential protection during chipping, wire brushing, and grinding operations. The lens is manufactured from high-grade polycarbonate, a thermoplastic polymer chosen for its exceptional impact resistance and optical clarity. With dimensions measuring 8.4 inches in height, 8.6 inches in width, and a structural depth profile of 0.8 inches, it offers comprehensive facial coverage that integrates seamlessly with the compatible headgear assembly.

A defining technical feature of this lens is Miller's proprietary High-Definition View (HDV) technology. Unlike standard injection-molded lenses that often introduce refractive aberrations and peripheral distortion, HDV technology is developed to maintain optical neutrality across the viewing surface. This ensures that operators perceive the workpiece with absolute sharpness and accurate spatial depth, which is critical for precision material removal tasks. The optical quality is further complemented by the material's inherent filtration capabilities, blocking up to 99.9% of harmful UVA, UVB, and UVC radiation, thereby protecting the user's eyes from non-ionizing radiation sources often present in industrial settings.

From a compliance and safety perspective, the 288275 lens is certified to meet both ANSI Z87.1+ and CSA Z94.3 standards. The ANSI Z87.1+ designation specifically indicates that the lens has passed high-mass and high-velocity impact tests, ensuring it can withstand the kinetic energy of flying debris generated during aggressive grinding or machining. It is important to note that while this lens provides robust impact protection, it is a clear lens intended for mechanical protection only and does not provide the shade filtration required for arc welding. It serves as a critical maintenance component for safety managers ensuring their PPE inventory meets current regulatory safety requirements.
