Do Face Shields Alone Count as Eye Protection Under ANSI Z87?

• Face shields are secondary protection and require primary eyewear like safety glasses.
• Particles and liquids may bypass shields through the “bottom gap” near the cheeks.
• OSHA 1910.133 mandates wearing primary Z87 protection under any face shield.
• The Z87+ mark proves a shield passed high-velocity and high-mass impact tests.

The ANSI Z87.1-2003 standard draws a hard line between two levels of gear. Primary eye protection, like safety glasses or goggles, is your first defense against direct impact. We classify face shields as secondary protection. They cover the whole face but aren’t enough to guard eyes alone.

If you are out in the field without glasses under that shield, you are one stray chip away from a recordable injury. A shield stops large debris or heat, but it does not meet the legal eye protection requirement by itself. You must wear Z87-rated spectacles or goggles underneath the visor.

The ANSI Z87.1-2003 text defines these devices as supplemental. They add a necessary layer for the face during heavy grinding or chemical handling. However, they rely on primary protectors to stop high-velocity fragments. Jobsite safety depends on understanding this specific distinction.

Section 14 of the standard outlines the High Mass Impact Test. We drop a 500g conical, pointed projectile from a height of 127 cm. If the lens fractures or the frame lets go of the window, it fails. This test simulates a heavy tool or a large piece of debris hitting you at a low speed.

Testers also use a 6.35 mm steel ball for velocity testing. For a shield to earn the Z87+ mark, it has to withstand that ball moving at 300 ft/s. This is significantly faster than the requirements for safety glasses. This marking tells you the gear is rated for high-impact environments.

Velocity requirements for high impact:

• Spectacles: 150 ft/s
• Goggles: 250 ft/s
• Face shields: 300 ft/s

OSHA 1910.133 is clear: employers have to provide protection that actually works for the hazard. For impact or chemical tasks, the law requires a shield to be used with safety glasses. Wearing a shield alone is a citation waiting to happen and leaves a worker’s vision at serious risk.

Think of the shield as a supplemental wall. It takes the brunt of the heat or heavy chemical splashes that glasses cannot handle. But those glasses or goggles are the final line of defense. They catch the smaller projectiles that inevitably navigate the gaps left open by the curved plastic shield.

Prescription wearers do not get a pass. You cannot just throw a shield over your street glasses and call it a day. You need Z87-rated protection, either through safety glasses designed to fit over your frames or by using Z87-rated prescription safety lenses.

Contact lenses are not protective gear. In a dusty or chemical shop, they can trap irritants against your cornea. If you wear contacts, the rules do not change. You still need that primary layer of goggles or safety glasses underneath your secondary face shield to remain compliant.

Face shields alone do not count as sufficient eye protection. Layered safety is the only way to operate on a professional jobsite. Before you pick up a grinder or open a chemical drum, look for the Z87 or Z87+ markings. Choosing the right combination of primary and secondary gear is what keeps you out of the hospital and on the clock.
