Which type of frame is often recommended for high prescription lenses?

Full-rimmed frames are often recommended for high prescription lenses because they provide the necessary structural support and stability that such lenses require. High prescription lenses can be heavier and thicker, and full-rimmed frames can help to properly encase and support these lenses, reducing the risk of breakage. The design of full-rimmed frames allows for better weight distribution and minimizes the potential for distortion at the edges of the lenses, which is particularly important when dealing with stronger prescriptions. Additionally, full-rimmed frames can accommodate various lens shapes and sizes, providing flexibility in the dispensing process.

In contrast, while thick plastic frames may seem like a sturdy option, they typically are not always designed to handle the weight of high prescription lenses as effectively as full-rimmed frames. Thin metal frames and rimless frames tend to be less durable and can sometimes exacerbate issues such as lens thickness and edge distortion, making them less suitable for high prescriptions. Therefore, for the best performance and comfort when accommodating high prescription lenses, full-rimmed frames are clearly the preferred choice.
