What is the Central Posterior Curve (CPC) commonly referred to?

• A. Intermediate Curve
• B. Base Curve
• C. Peripheral Curve
• D. Optic Curve

Answer: (B)

The Central Posterior Curve (CPC) is commonly referred to as the Base Curve. This term is used in optics, particularly in the design of contact lenses, to describe the primary curvature of the lens that sits closest to the eye. The Base Curve is essential in ensuring proper fit and comfort, as it helps determine how the lens will align with the curvature of the cornea. A correctly chosen Base Curve allows for optimal oxygen transmission, stability on the eye, and an appropriate level of tear exchange, which is crucial for eye health. While the other terms like Intermediate Curve, Peripheral Curve, and Optic Curve refer to other aspects or components of lens design, they do not specifically encapsulate what the Central Posterior Curve represents. The focus of the term "Base Curve" in relation to the CPC highlights its critical role in the overall functionality and fit of contact lenses.
