What is the radius of the cornea?

• A. 6.85 mm
• B. 7.25 mm
• C. 7.55 mm
• D. 7.85 mm

Answer: (D)

The radius of the cornea is an important measurement in ophthalmology and optics, as it relates to the curvature and optical properties of the eye. The typical average radius of the cornea falls within the range of approximately 7.5 to 8.0 mm. Therefore, a radius of 7.85 mm is consistent with the common values used for the corneal radius in clinical practice. This curvature significantly influences how light is refracted as it enters the eye, ultimately impacting vision quality. Additionally, the radius of curvature can vary from one individual to another, with some people having flatter corneas and others having steeper ones. However, the value of 7.85 mm reflects the average radius found in many sources, making it a reasonable answer in this context for understanding normal corneal dimensions.
