An optical lens is a transparent object that can converge or diverge light incident light beam. This lens comes in various shapes, ford, and sizes depending on the use of application ranging from magnification, correction of optical aberrations, image projection, and focusing. Lens are mainly of two types, convex lens which is converging, and concave which is diverging. Most optic Lenses are made of high-tech plastics. The principle of optical lenses has been used in various areas in Optical Lenses, including life sciences, imaging, industrial, or defense and military, etc. These new ones are lighter, don’t break as easily as glass, and can be treated with a filter to shield your eyes from damaging ultraviolet (UV) light. The follodg lenses are lighter, thinner, and more scratch-resistant than glass or the older plastic types. The lens comes in types of shapes just like optical windows concave, convex, plano-concave, plano-convex. Optical lenses are used to converge or diverge light, Optical Lenses, which may consist of a single or multiple elements, are used in a wide variety of applications from microscopy to laser processing.
Types Of Optic Lenses
Single Vision Lenses
This is just the basic lens, which is meant for correcting eye defects be it short-sightedness or long-sightedness. It is simply the cheapest one can get.
Bifocal Optic Lens
This optic lens contains two optical powers to help accommodate vision for both near and far. Most of this list contains the distance lens prescription on top while the near vision prescription info and the down part.
Trifocal Lenses
The trifocal lens comes with three optical powers, which include distance, intermediate, and near vision, with two segmenting lines to delineate the powers. The intermediate segment is located above the segment for near vision and helps view objects at arm’s length, such as a computer, or car dashboard.
Progressive Lenses
The progressive lens allows multiple vision fields to be incorporated into a single lens without any clear distinction between the fields themselves. The power in the lenses changes progressively from far-to intermediate. This is why progressive lenses are often referred to as “no-line” bifocals or trifocals. It is multiple focal, with a similar principle as bifocal and trifocal.
Polycarbonate Lenses
This impact-resistant light lens is thinner than plastic. This lens is strong and shatter-proof and provides 100% UV protection. They are ideal for strong prescriptions since they do not add thickness when correcting vision, minimizing any distortion. This lens is resistant to impact and is 10 times stronger than our conventional lenses. They also come with built-in UV protection and are mostly used in sports.
High Index Plastic Lenses
High Index Plastic lenses are a special kind of corrective lens with a high refractive index more than conventional lenses. This high Index falls between 1.59 to 1.74.
Aspheric lenses
Aspheric lenses are lenses that allow optical designers to correct aberrations using fewer elements than conventional spherical optics and come with so many covertures.
Computer Lenses
Computer glasses are prescription glasses for ocular health, that are designed to wear when doing computer work. They allow you to focus your eyes on a computer screen.
Photochromic lenses
This light comes with a unique feature that allows it to darken up when it is brought out to sunlight but returns to its original color when it’s indoors. And it’s very helpful in patients who have computer vision syndrome.
Polarized sunglasses
Polarized sunglasses remove glare from horizontal surfaces like snow and water. They come with the best coating just like that of film aro research optics.
