The OG 621 IShield is a polycarbonate Side Shield that fits the OnGuard 621 Prescription Safety Glasses. Available in clear, the OnGuard IShield is mounted from the inside, not compromising the look of the frame. In addition, the IShield attachment is less bulky and can be used as a removable shield or locked into position for a permanent installation.
