Diamond turning is widely used in industries such as aerospace, defense, telecommunications, and photonics, where precise optical components are required for various applications, including laser systems, imaging systems, and precision instrumentation.

Glasses with lenses that help the wearer see things up close. Many people need reading lenses as they get older due to a common condition called presbyopia.

All single vision EyeBuyDirect lenses come standard with an anti-reflective coating. High-index lenses naturally reflect more light, so this is an important addition if you’re interested in thinner lenses.

Precision: Diamond turning is capable of achieving extremely high levels of precision and accuracy, with tolerances in the sub-micrometer range. This makes it ideal for manufacturing optical components, such as lenses, mirrors, and prisms, where precise surface shapes and dimensions are critical.

Blue light filtering lenses filter blue-violet light (blue-violet light is between 400-455nm, as stated by ISO TR 20772:2018​ and can accelerate aging of the retina) emitted mainly by the sun outdoors and indoors through windows, plus some artificial light sources like digital screens and fluorescent lights.

Cost-effectiveness: While diamond turning equipment and tooling can be expensive, the process offers cost advantages for producing small to medium quantities of high-precision components compared to traditional grinding or polishing methods.

Diamond turning, also known as diamond machining or diamond cutting, is a precision machining process used to produce high-quality optical surfaces and components with extremely tight tolerances. It involves the use of a single-point diamond cutting tool to remove material from a workpiece, typically made of metals, plastics, or optical materials like glass or crystals.

Glasses with Transitions® lenses automatically darken in sunny conditions and become clear when it’s darker. This allows them to work as both eyeglasses and sunglasses.

Versatility: Diamond turning can be used to machine a wide range of materials, including metals, plastics, ceramics, and optical materials. It is particularly well-suited for hard and brittle materials that are difficult to machine using conventional methods.

Anti reflectivecoatingdisadvantages

In diamond turning, the cutting tool, which has a diamond tip, is controlled with high precision and moved relative to the workpiece along multiple axes using computer numerical control (CNC) or other automated systems. The diamond tool is brought into contact with the rotating workpiece, and material is gradually removed in a controlled manner to achieve the desired shape and surface finish.

Glasses with single vision correction lenses. They help with seeing either at a distance or near, depending on the wearer’s needs.
