Sir Isaac Newton is credited with inventing the first practical reflecting telescope, which used a concave mirror as the primary optical element instead of a lens. This design helped to minimize chromatic aberration, a common issue associated with traditional refracting telescopes that used lenses.

Colored contact lenses are typically made by combining colored pigments with the contact lens material during the manufacturing process. The pigments are embedded within the lens material to give the desired color effect. Additionally, some colored lenses have a printed design on the surface to enhance the color or create special effects.
