Brass Knuckle bifocal corrective safety glasses

Bifocal safety lenses provide close-focus accommodation for those with presbyopia, a normal part of aging vision that causes a decrease in the ability to focus sharply on nearby objects. Brass Knuckle’s protective readers help prevent the hazardous practice of switching back and forth between regular safety glasses and reading glasses on the job. BKReaders’ 9 base curve clear lenses are made for clear, crisp and distortion-free vision. Tough 100% polycarbonate lenses block 99.9% of the sun’s ultraviolet rays.
