IMPROVEMENTS IN AND RELATING TO VISORS |
摘要 |
A glare visor (13) for reducing ambient light intensity perceived by a wearer viewing a head-up display (3) employing display light (7) including a given wavelength(s) of light. The visor includes a visor body comprising optically transparent material which is partially absorbing of light of visible optical wavelengths thereby to reduce the intensity of ambient light transmitted therethrough to the wearer. A transparent optical coating (12) is formed upon a surface of the visor body which is partially transmissive of light of visible optical wavelengths amongst which it is preferentially transmissive of light of a sub- range of wavelengths for including therein the wavelength(s) of display light. This permits a perceived enhancement of contrast between display light (7) relative to ambient light (8). |
