Collier's sign Unilateral, or more commonly bilateral, eyelid retraction that exposes an unusual amount of the sclera of the eye above and below the iris; it gives the person a frightened or startled expression. It is due to a midbrain lesion. See Parinaud's syndrome.
sign convention A set of conventions regulating the direction of distances, lengths, and angles measured in geometrical optics. The most common is the New Cartesian Sign Convention. It stipulates: (1) All distances are measured from the lens, refracting surface or mirror. Those in the same direction as the incident light, which is drawn travelling from left to right, are positive. Those in the opposite direction are negative. (2) All distances are measured from the axis. Those above are positive. Those below are negative. (3) Angles are measured from the incident ray to the axis, with anticlockwise angles positive and clockwise angles negative. (4) The power of a converging lens is positive and that of a diverging lens is negative (Fig. S7). See focal length; Lagrange's law; law of refraction; Newton's formula; fundamental paraxial equation.
