Study Notes
Early Contributions to Contact Lens Development
- In 1508, Leonardo da Vinci designed the first refracted surface on the cornea, a precursor to modern contact lenses.
- Da Vinci's concept involved a large glass bowl filled with water, which theoretically corrected vision by immersing the eyes in water.
- In 1636, Descartes proposed a more direct approach, suggesting the application of a water-filled tube to the eye to correct refractive errors.
- The first contact lens was created by Friedrich Anton Müller, a manufacturer of artificial eyes.
