Abstract
A face mask safety shield structure having a shield support formed of a fire-retardant material with an adjustable head band for adjusting the structure to fit various sizes of user heads. A visor is attached to opposite sides of the shield and enables a user to raise the visor from a frontal horizontal position with respect to the shield support. The structure has a full length lens assembly of a length to fully cover the user's eyes and face and is removably secured to the visor to extend vertically downward from the visor when the visor is in the horizontal position to cover a user's eyes and face. The assembly has a tinted section positioned above a clear section with the tinted section formed to have a length less than the length of the clear section for shielding the eyes of the user. With the visor in the frontal horizontal position the user may look through both the clear and tinted sections and move the visor upward in an arc to swing the lens assembly away from the user's eyes and face.
