| Providing an optical lens with a convex surface, where the convex surface is coated with an anti-smudge topcoat, making the optical lens unsuitable for edging. | |
| Fixing a mounting component on the convex surface of the optical lens, preferably at its center, using a paste pad that adheres to both the mounting element and the convex surface of the optical lens, forming a mounting element/optical lens assembly. | |
| Placing the mounting element/optical lens assembly in a grinding machine to securely hold the optical lens in place. | |
| Edging the optical lens to the intended size and shape. Before fixing the mounting element, the anti-smudge topcoat on the convex surface of the optical lens is pre-treated with a solvent selected from alkanols and dialkylketones under mechanical stress. |
The present creation relating to the field of edging optical lenses, such as ophthalmic lenses and more particularly coated ophthalmic lenses for conforming the lenses to the required dimensions and shapes of the lens frames in which they are projected to be accommodated.
Mounting lenses in a frame is a highly specialized stage requiring advanced technology. This operation ensures that the lenses fit the frame shape with precision.
Various types of edging machines are employed during the lens edging process. We also utilize specialized machines for cutting lenses to meet the latest specifications.
Each lens is meticulously inspected for cracks or chips that might prevent it from fitting securely in the frame. The lenses are also checked to ensure they match the correct eyepiece. Holding both lenses over the frame helps verify their proper alignment.
It is absolutely crucial that the ophthalmic lens is firmly and securely held during the edging process, as improper execution can damage or ruin the lens.
At BM Optical Lab Ltd., we employ state-of-the-art machinery to cut and edge all types of high-wrap sports frames available in the market, ensuring precision and excellence in every lens we produce.
