Image display apparatus (26) comprising a display panel (28), a screen (30), and image relay apparatus (2), the optical relay apparatus (2) comprising at least one aspherical polymer lens (8, 10, 12,14) and at least one spherical glass lens (4, 6), the said lenses being such that an image is able to be relayed from the display panel to the screen with a predetermined distortion, the optical relay apparatus (2) being such that it has a final aspherical polymer lens (14) which is the said aspherical polymer lens (8, 10, 12, 14) or one of the said aspherical polymer lenses, the final aspherical polymer lens (14) has a first depression (16) on a first side (18) and a second and larger depression (20) on a second side (22), the first side (18) being nearer to the display panel (28) than the second side (22), and the final aspherical polymer lens (14) directs light towards the screen (30) such that the direction of light rays complements the operation of an eyepiece used to view the screen (30).
