- Bridget Riley is Britain's leading exponent of Op art, the school of art that exploits optical phenomena so that a work appears to flicker, pulsate or move.
- Major works of the 1960s are black-and-white paintings in which intricate geometric patterns were designed to produce striking optical effects.
- In 1968, Riley won the International Painting Prize at the Venice Biennale.
- Riley's calming 1983 interior at the Royal Liverpool Hospital is said to have caused a significant fall in vandalism and graffiti.
