Abstract
An article of headwear (10) includes a solid transparent fully carbonate block (18). The block lies on top of the wearer's head and defines a non-straight light path to the wearer's eyes. The block does not obscure the majority of the normal field of vision for the wearer but can be seen when the wearer looks upwards. The upper surfaces 24 of the block allow internal reflection of light through the block and the rear end of the block is open and faces backwards so that by looking upwardly into the block a wearer can obtain a view of what is behind him. The article of headwear may be a motorcycle helmet for example. In another embodiment of the invention a display screen is located at the rear of the block so that it can be seen through the block when the wearer looks upwardly into the block.
