Which tool can verify the lens diameter, optic zone, and peripheral curve width simultaneously?

The measuring magnifier is particularly effective for simultaneously verifying the lens diameter, optic zone, and peripheral curve width due to its design and functionality. This tool combines magnifying features with measuring scales, allowing professionals to closely examine the contours and measurements of contact lenses without the need for multiple instruments.

When utilizing a measuring magnifier, the user can enhance their ability to measure specific features directly on the lens surface while observing any defining characteristics that may require more detail than typical calipers would provide alone. The integrated magnification facilitates precise measurement and assessment, aiding in ensuring that lenses meet prescribed specifications effectively.

In contrast, other options have limitations. A microscope is primarily used for detailed examination rather than direct measurement, focusing on microscopic details rather than the larger dimensions needed for contact lenses. A caliper is excellent for measuring but does not provide magnification, which can hinder visibility when examining intricate features of lens components. The optical comparator, typically used for more complex dimensional analysis, may not provide the simultaneous convenience that a measuring magnifier offers, as it often requires a more elaborate setup and is focused on profile comparisons rather than real-time direct measurements.

Therefore, the measuring magnifier stands out as the preferred choice for this task.
