What is an important difference between soft and rigid contact lenses?

• A. Durability
• B. Comfortability
• C. Price
• D. Thickness

Answer: (B)

The primary distinction between soft and rigid contact lenses lies in their comfort due to the materials used and their designs. Soft contact lenses are made of flexible, hydrophilic materials that allow them to conform to the shape of the eye and absorb moisture. This flexibility usually offers a more comfortable fit immediately upon application, catering to individuals who may find rigid lenses less agreeable. In contrast, rigid gas permeable (RGP) lenses are made from firmer materials that do not conform to the eye's shape as readily. While these rigid lenses can provide excellent vision corrections and allow for adequate oxygen transmission, individuals new to them might experience a longer adaptation period and report less initial comfort compared to their soft counterparts. This difference in comfort is a crucial consideration for users when deciding which type of lens to wear, as comfort can significantly influence overall satisfaction and adherence to lens-wearing schedules. Other factors such as durability, price, and thickness can vary and depend more on specific products within each category rather than defining characteristics that differentiate soft from rigid lenses.
