What is the purpose of grinding the outer carrier portion of a lenticular lens?

The purpose of grinding the outer carrier portion of a lenticular lens primarily focuses on reducing weight and edge thickness. Lenticular lenses are designed to minimize the amount of material needed while still providing effective optical corrections for vision. By grinding the outer edges, the lens can be made thinner and lighter without compromising on the visual performance or the structural integrity of the lens.

This reduction in thickness and weight is particularly beneficial for patients who may have bulky or heavier lenses in traditional designs, leading to increased comfort and wearability. Lighter lenses are easier to handle and reduce strain on the wearer, especially when glasses are worn for extended periods. Thus, the grinding process is a critical step in the manufacturing of lenticular lenses that enhances their usability and comfort for the wearer.

In contrast, enhancing clarity, improving aesthetics, and increasing durability are secondary effects of the grinding process but do not represent its primary aim. While these factors may be influenced by the manufacturing process, the principal focus in this context remains on the weight and edge thickness.
