- ‘It is easier to see the effect of parallax the closer the foreground object is to you.’
- ‘Each element was then centered in the lens to decrease distortion from lens curvature or parallax.’

- ‘Their parts evolve in a kinetic parallax of curves and angles that create a shifting perceptual spectacle.’
- ‘The work on double stars had been undertaken as a continuation of his father's work which attempted to measure the parallax of a star.’
- ‘He also gives the tables of the longitudinal and latitudinal parallaxes for certain geographical latitudes, tables of eclipses, and tables of the visibility of the moon.’
- ‘To measure the parallax, Bradley intended to make a series of observations, noticing how it moved against the background.’
Late 16th century (also in the general sense ‘fact of seeing wrongly’): from French parallaxe, from Greek parallaxis ‘a change’, from parallassein ‘to alternate’, based on allassein ‘to exchange’ (from allos ‘other’).
