visor

häikäisysuojus, lippa

silmikko A part of a helmet, arranged so as to lift or open, and so show the face. The openings for seeing and breathing are generally in it.
1786, Francis Grose, A Treatise on Ancient Armour and Weapons, page 7:

A close helmet entirely covers the head, face, and neck, having on the front perforations for the admission of air, and slits through which the wearer may see objects around him, this part which is stiled the visor lifts up by means of a pivot over each ear.

No visor does become black villainy So well as soft and tender flattery.
