Fixing Scratched Lenses on your Glasses. Tips worth knowing to help removing scratches from your glasses lenses. There are fewer things in life more annoying than the pesky distraction of a scratched lens on your glasses, especially when it's right in your eye line and distracts you from concentrating on your current task!

Before the lens undergoes further grinding, the lens must be blocked, or mounted, to begin the process. Blocking involves mounting lenses onto a convex or concave surface (inverse of the tool being used) with pitch or wax. A lens can be blocked individually (Figure 3a), but more often, many lenses with the same radii are mounted on one surface

In the beginning grinding of spectacle lenses was done entirely by hand. Thus chroniclers report dozens of unqualified workers spending days giving the blanks supplied by the glassworks their desired shape. On grinding machines, whose antecedent was the potter's wheel, one side of the lens was ground to a shape corresponding to a spherical ...

A spherocylinder lens is usually made by grinding a spherical surface on one lens surface (the front surface for most spectacle lenses) and a toric surface for the other lens surface (the back surface for most spectacle lenses). barrel form tire form

When the lens is removed from the generator the back surface is rough, with a frosted appearance, from the process of grinding the prescription onto the blank. This multistep process is called "Fining and polishing". The process involves placing the lenses into a Finer which uses a polishing block called a lap. The first step in the finer ...

The power of a spectacle lens is obtained from a combination of the powers of its front and back surfaces. Each surface of a lens may be either convex, concave, or flat (plano or zero power), resulting in six general lens shapes ().Spectacle lenses used to correct refractive errors are almost always meniscus lenses, with both lens surfaces concave toward the eye.
