An apparatus for releasably locking a protective eye lens to the housing of a protective face cover is disclosed. The apparatus is configured to have an inner and outer lock. The inner lock couples the protective eye lens to the housing. The inner lock can release the protective eye lens from the housing through the use of a release unit. An activator on the release unit is guarded by the outer lock to prevent inadvertent movement of the activator and consequent unintended release of the protective eye lens from the housing.
