What is the typical width of an adult human eye?

• A. 20 mm
• B. 24 mm
• C. 28 mm
• D. 30 mm

Answer: (B)

The typical width of an adult human eye is approximately 24 mm. This measurement refers to the horizontal diameter of the eyeball, which is a standardized value used in ophthalmology. Understanding the dimensions of the eye is essential for various clinical applications, such as fitting contact lenses, calculating intraocular lens power for cataract surgery, and assessing overall eye health. The other options present widths that are not consistent with the average anatomical measurements observed in adults. For instance, 20 mm is narrower than what is typically found in adult eyes, while widths of 28 mm and 30 mm exceed the average size and could indicate unusual conditions or larger than normal eyes. Therefore, 24 mm stands out as the most accurate representation of the typical width of an adult human eye.
