These lens defects can frequently be reduced by limiting the outer edges of the lens from exposure to light using diaphragms, and also by utilizing aspherical lens surfaces within the optical system. The highest-quality modern microscope objectives address spherical aberrations in a number of ways including special lens-grinding techniques ...
Optical fiber lens, is a kind of special optical fiber. It is made by grinding the tip of the fiber into the shape of a certain lens such as angle-polished, wedge-shaped, and tapered. The optical fiber lens is used to minimize the spot size, change the optical path, or transform the optical mode in the optical system.

Figure 2: Lens-grinding machine of Christiaan Huygens (From his 'Opuscula Posthuma', published posthumously by Janssonio Waesbergios, Amsterdam, 1728 ) What made it very difficult to produce usable lenses, as the Huygens brothers soon found, was that the whole art of lens grinding was surrounded by secrecy.

Lens Grinding Optical lens manufacturers use our custom developed torque and moisture resistant lens grinding tapes to place and stabilize lenses during various stages of their production processes. Tape solutions for pads and laminates designed to perform on glass surfaces, including coated, mineral and organic glasses.
Over the next several decades, lens-grinding and polishing techniques improved gradually. A specialized craft community of telpe makers slowly developed. These craftsmen worked to produce better spherical lenses with decreased curvature (and a longer focal length ) which improved the quality of telpes but made them longer.

In a traditional cast plastic lens, 80% of the original lens blank material is wasted as the prescription is ground into the blank. With the same amount of material, ARfusion™ can produce five lenses. Grinding the semi-finished blank also requires 50-100 liters of water, which becomes filled with polymeric waste (micro plastic).

Plastic as well as glass lenses are produced by successive stages of fine grinding, polishing, and shaping. While the same process is used to produce lenses for telpes, microscopes, binoculars, cameras, and various projectors, such lenses are usually larger and thicker and require greater precision and power.
The lens would then go to the surface finers and polishers to complete the grinding process. Traditional surfacing is limited in the number of customizations of the progressive designs because of the physical constraints of traditional tools. ... Digital surfacing technology allows labs to produce higher quality lenses. Digital surfacing also ...
Canon has achieved an overwhelming level of machining precision, including the ability to grind a lens surface to a tolerance within 100 nm (nanometers) 3, then polish it to an even higher degree of precision, reducing surface roughness reduced to within a 1 nm range.
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
