Leonardo da Vinci was the first person to propose a contact lens system. In the sixteenth-century he described an optical method
for correcting poor vision. Da Vinci’s idea was to place the eye against a short, water-filled tube sealed at the end with a flat lens. In this process, the water came in contact with the eyeball and refracted light rays much the way a curved lens does. -paraphrased from Charles Panati’s History of Contact Lenses— Which sentence would MOST logically conclude this paragraph?
