In general, which of the following indicates a frame is a good option for strong prescriptions?

When considering frames for strong prescriptions, thicker rims stand out as the most beneficial choice. Strong prescriptions necessitate certain accommodations in frame design to ensure both visual clarity and structural integrity. Thicker rims help to better support high-index lenses, which are often used for stronger prescriptions to minimize thickness and weight. By providing additional support, thicker rims can also help reduce the chances of lens popping out of the frame and mitigate the visual distortions that may arise from thinner frames.

In contrast, round shapes and narrow bridges might not provide sufficient stability or support for heavy lenses, making them less suitable for strong prescriptions. Lightweight materials, while advantageous for comfort, do not inherently provide the necessary strength or support needed for thicker lenses associated with high prescriptions. Thus, the emphasis on thicker rims aligns correctly with the requirements for accommodating strong prescriptions while ensuring both durability and aesthetic appeal.
