Examples
- Dioptrics explains how light bends when passing through a lens.
- The study of dioptrics is essential for designing eyeglasses and cameras.
- Newton made important contributions to dioptrics through his experiments with prisms.
- Dioptrics differs from catoptrics, which focuses on reflection rather than refraction.
- Modern optical engineering relies heavily on principles of dioptrics.
