Abstract: An article of eyewear comprises a shade 4 that may be worn independently or attached to the frame 3 of spectacles or sunglasses. The shade 4 is shaped and positioned not to obscure the field of view of the wearer when looking straight ahead but to obscure the field of view of the wearer when looking either upwards or downwards, apart from in the areas of two unobscured apertures 8 formed as slots from the edge of the shade 4. If the shade 4 is above the field of view, it permits a player of a racquet sport such as tennis to see the ball during a serve or other overhead shot, while being shielded from the glare of surrounding overhead light. If the shade 4 is below the field of view, it permits a skier to view the piste below, while being shielded from the glare of the surrounding snow. The two apertures 8 may be aligned to converge on a fixation point a metre away or many metres away respectively for racquet sports or for downhill skiing.
