The invention of soft contact lenses in the 1960s by [[Otto Wichterle]] revolutionized the industry. Made from hydrogel, these lenses offered greater comfort and oxygen permeability compared to rigid lenses. The development of soft lenses was facilitated by the synthesis of [[hydrophilic]] polymers, which allowed lenses to retain water and remain flexible. This breakthrough expanded the market for contact lenses, making them accessible to a broader audience. | The invention of soft contact lenses in the 1960s by [[Otto Wichterle]] revolutionized the industry.
