The Graham Field 9678 (Grafco) safety glasses are specifically engineered for outdoor clinical and industrial applications where lighting conditions vary. These glasses feature high-visibility amber lenses that block the blue visible light spectrum, providing maximum contrast enhancement in low-light or overcast conditions. The lightweight, contemporary frame includes extended wraparound coverage and a molded nose bridge for a secure, comfortable fit during long shifts. Like the rest of the Grafco line, the polycarbonate lenses are treated with a scratch-resistant hard coating and provide critical UV protection.
