Which frame style is often more accommodating for higher prescription lenses?

Round frame
Cat-eye frame
Full-rim frame
Half-rim frame

The correct answer is: Full-rim frame

The full-rim frame style is commonly more accommodating for higher prescription lenses due to its design and structural integrity. These frames surround the entire lens, providing enhanced stability and support, which is particularly important for thicker or heavier lenses often required with higher prescriptions. The full rim helps to secure the lenses more effectively, reducing the risk of lens distortion and allowing for a wider range of lens shapes and styles that can adequately accommodate strong prescriptions. In contrast, half-rim or rimless frames can be limited in their ability to support thicker lenses. While they may offer aesthetic advantages or a lightweight feel, they often lack the full encasement that helps to stabilize heavier lenses. Styles like round or cat-eye can also be less effective in accommodating higher prescriptions when compared to full-rim frames, as they may not offer the same level of lens stability and could pose challenges regarding lens thickness and edge support.
