| Providing an optical lens having a convex surface, the convex surface being provided with an anti-marked top coat representing the optical lens unsuitable for edging. | |
| Fixing a mounting component on the convex surface of the optical lens, preferably on its center, by means of an paste pad sticking both to the mounting element and the convex surface of the optical lens to form a mounting element/optical lens assembly | |
| Placing the mounting element/optical lens assembly in a grinding machine so that the optical lens is definitely maintained | |
| Edging the optical lens to the intended size and shape, wherein, prior to step (b) of fixing the mounting element, the anti-smudge topcoat on the convex surface of the optical lens is pre-treated with a solvent selected from the group consisting of alkanols and dialkylketones under a 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.
The mounting of lenses in a frame is a little-known stage which requires leading-edge technology. This operation results in lenses which fit the shape and frame to perfection.
Various kinds of edging machines are used during the process of lens edging. We also use special machines for cutting the lens to adjust in as per the latest specification.
Lenses are checked for any cracks or chips that might prevent them from staying in the frame.
The lens is Inspected to make sure you have the correct lens for the eyepiece. You can hold both lenses over the frame to match up proper sides.
It is extremely essential that the ophthalmic lens be firmly and safety held during the edging step as an improperly executed edging step can ruin the ophthalmic lens.
We, at BM Optical Lab Ltd., also have new and most modern machines to cut all kinds of high wrap sports frames available in the market.
