What is used in the eyes to keep the shape of the eye intact and prevent wearing?

• A. swivels
• B. thimbles
• C. clips
• D. rings

Answer: (B)

The correct choice refers to thimbles, which are used in various applications to maintain the integrity and shape of an object by providing a supportive structure. In the context of the eyes, thimbles can be likened to the components that ensure the eye retains its spherical form and assists in resisting deformation under pressure. These components are crucial because they help maintain the optimal shape necessary for proper vision.

Other options like swivels, clips, and rings are not typically associated with the function of shaping and supporting the eyes. Swivels are more related to jointed connections in mechanical contexts, clips serve primarily for fastening or holding, and rings might be used in other structural roles but do not directly relate to maintaining the form of the eye. Understanding the role of thimbles in this context clarifies their function as essential elements that contribute to the structural integrity of the eye.
