ESS Recon High Adrenaline Prescription Sunglasses offer the style and protection that ESS is known for, along with high performance, impact resistant polycarbonate optical lenses, prepared custom to your prescription. Eye Safety Systems understands that not all hazards exist on the battlefield, so they created the ESS High Adrenaline Recon Sun Glasses' frames to be comfortable and cool enough for downtime, yet functional and rugged enough to provide protection against unexpected situations that occur away from the front lines. Only high-impact polycarbonate prescription lenses are used to optimize impact resistance in the frame of these ESS prescription sunglasses. Your pair of prescription sunglasses by ESS will meet and exceed ANSI Z87.1 and MIL-PRF-31013 spectacle impact standards, even in prescription form. A carrying case and lens cleaning cloth are included with your High Adrenaline series sunglasses. Though the Recon comes packaged with prescription lenses, you can modify it with the lens of your choice using the ESS Rx Ready Prescription Lens Inserts. For a high-durability, high-style, highly effective pair of prescription sunglasses, wear the Eye Safety Systems High Adrenaline Recon Medium Frame Rx Sunglasses.
