ESS CDI Replacement Lens

The ESS CDI Replacement Lens is a precision optical component engineered for operators and tactical professionals who demand field-proven eyewear performance. These 2.2mm polycarbonate replacement lenses deliver 100% UVA/UVB protection while reducing glare and eye strain—critical for extended patrol duty, range training, and outdoor operations where optical clarity directly impacts situational awareness and shooter precision.

ESS's CDI Replacement Lenses are available in eight distinct optical profiles: Clear, Smoke Gray, Hi-Def Yellow, Hi-Def Bronze, Mirrored Copper, Mirrored Gray, Mirrored Silver, and Mirrored Gray Polarized options. The polarized variants specifically attenuate reflected glare—essential when operating near water, snow, or high-reflectance surfaces common in maritime, alpine, or desert environments. The 2.2mm polycarbonate construction provides ballistic-rated impact resistance while maintaining optical fidelity. The CDI's Lateral Exchange System (LES) enables rapid lens interchange without tools, allowing operators to switch optical profiles to match changing light conditions or mission requirements within seconds.

These replacement lenses are designed for law enforcement, military personnel, competitive shooters, and outdoor professionals who rely on the CDI platform. Whether transitioning from low-light indoor training to full-sun outdoor operations, or managing glare during extended fieldwork, the modular lens system eliminates the need to carry multiple complete eyewear frames. The quick-swap capability and diverse lens options make this system efficient for budget-conscious operators who want optical versatility without purchasing separate eyewear sets.

ESS Eyewear is recognized within professional tactical and law enforcement communities for manufacturing eyewear that meets rigorous performance standards. Replacement lenses offer cost-effective frame longevity and allow shooters and operators to maintain their preferred frame geometry while updating optical properties to suit seasonal or mission-specific demands. Weighing just 0.04 lbs, the ESS CDI Replacement Lens adds negligible weight while delivering optical performance that directly supports shooter accuracy and situational clarity in the field.
