1. of or relating to refraction of light through a lens or transparent medium
Usage: technical; optics
2. of or relating to the science of dioptrics, which deals with the refraction of light
Usage: technical; physics

Examples

• The dioptric properties of the lens determine how light is bent as it passes through.
• A dioptric system uses refraction to focus light onto a focal point.
• The telescope's dioptric design allows for clear magnification of distant objects.
• Dioptric power is measured in diopters for corrective eyeglasses.
• The dioptric effect of the curved glass surface was carefully calculated by the engineer.
