A lens is a transparent optical component that refracts light or other electromagnetic radiation and directs it to either a magnified or diminished image.<\/p><\/blockquote>\n

The vast majority of lenses are made from transparent materials, such as glass, plastic, and polymers. A Lens is a spherical device in which an incident beam of light converges to a single point, while also being refracted at its surface in a direction parallel to itself. It can be used as both convex and concave.<\/p>\n

Applications:<\/strong><\/p>\n

They are available in various sizes and shapes which fit on a spectacles frame. The main application is to eliminate or reduce eyestrain as well as strain on vision especially for people who spend long hours in front of computer screens or work under harsh lighting conditions. They can be used by people who have undergone cornea transplant, cataract surgery, and certain cases of glaucoma, short-sightedness and far-sightedness.<\/p>\n

They can be worn over prescription glasses too. Generally opticians offer a range of standard lenses that come with anti-reflective coating to make them comfortable while reducing glare and eye fatigue caused due to reflections from light sources like computer monitors, mobile phones etc. These lenses generally give clear vision at all angles from horizontal to vertical planes but are not suitable for extreme high impact activities that involve sudden acceleration or deceleration like sports.<\/p>\n

Manufacturing Process<\/strong><\/p>\n

The two stages of the plastic optical lens manufacturing process are preform and final processing. Preforms are created in a range of shapes and sizes at major plastic extrusion machines. The optical quality of raw materials is influenced by their properties during processing, whereas technical parameters (flow rate, temperature, and barrel length) and processing conditions influence their attributes during processing (running speed).<\/p>\n
