Astigmatic forms are lenses with at least one astigmatic surface—a surface that does not have a uniform curvature—and therefore lack rotational symmetry.

As individuals can have unique visual requirements, lens forms sometimes combine elements from different meniscus lens types to provide proper visual corrections.

Convex lens

These lenses have a spherical front surface and an atoric back surface (varying curvatures across the lens) and are also designed to correct ocular astigmatism.

Combining complex curvatures on both lens surfaces results in variable base curves and flatter lenses. Camber technology provides labs with advanced custom lens curves bespoke to a patient’s visual needs. The technology provides an optimal visual experience for even the most complex presbyopic prescriptions.

This is a generic term which technically encompasses all lenses that are not spherical, like progressives and free form lenses. Aspherical lenses are manufactured from spherical semi-finished blanks with one aspherical surface, usually in the form of a conicoid.

Away from the center of the lens, oblique aberrations can reduce optical quality. Minimizing this impact can significantly enhance wearer satisfaction and comfort. Technologies, like IOT’s Digital Ray Path 2, minimize peripheral blur common to lenses such as progressive lenses by incorporating a wearer’s accommodative capacity, creating a high-definition visual experience for wearers.

The focal point is a specific spot along the optical axis where light rays converge after passing through the lens. This spot is crucial because it is where objects come into focus. The distance from the center of the lens to the focal point is known as the “focal length.” Lenses with a short focal length bend and focus light more sharply, giving them greater optical power. This makes them ideal for applications like reading glasses that require magnifying close objects but less suitable for applications that require significant magnification, like intense corrective lenses. Conversely, lenses with longer focal lengths bend light more gently and have lower optical power, making them better suited for observing distant objects, like when piloting planes or viewing faraway horizons in landscape photography.

Combining control of mean power distribution and optimization for binocular performance is achieved with Steady Plus Methodology. This results in the eyes perceiving symmetrical powers for each gaze direction.

These are the simplest form and most commonly used, with two spherical surfaces. Spherical lenses have rotational symmetry around the imaginary line that joins the center of each surface.

Lens

As light moves through a lens, it refracts or bends.  Refraction allows the lens to either converge (focus) or diverge (diffuse) the light rays passing through it. The degree to which the light bends is determined by the lens's refractive index, which dictates how much the speed of light is reduced as it enters the lens material. This slowdown in speed is critical for manipulating light’s path, making it essential for designing optical lenses. Vision is corrected by focusing light precisely on the retina. Additionally, labs can manipulate how and where light converges or diverges by altering the shape and material of a lens.

An optical lens is crafted from transparent materials such as glass or plastic and is designed to manipulate light through refraction. These lenses bend light to bring images into focus, produce magnification, enhance projection, and correct optical aberrations. While cameras and telescopes also use optical lenses, they primarily serve as the foundation for vision-correcting glasses.

Convex lens imaging

Refraction drives optical lens technology, but it also collaborates with other factors, like shape and focal length, to manipulate light and images when a wearer looks through the lens.

The form of a lens refers to the physical curvature of the lens surfaces. The form and material of a lens significantly influence how it refracts light. Lenses can be convex, concave, or a combination of both, each form bending light differently. Convex lenses cause light rays to converge, focusing the light, while concave lenses cause light to diverge, spreading it out. The choice of material affects how much light slows down and must be considered when designing lenses to achieve the desired optical properties.

Though lens shape and lens type are closely related, they have distinct characteristics and impact the lens’s function differently.

Fresnel lens

Thanks to our Steady Methodology, the swim effect found in progressive lenses is reduced by controlling for unwanted cylinder power and changes to mean power in the periphery. The additional technology added to the lens design significantly reduces blurring around the edge.

Within these categories, lens shapes combine in ways that affect light refraction, prompting various changes in vision. The optical industry mainly uses a meniscus lens, while other subcategories are found in equipment ranging from projectors to telescopes.

Tunable lens

These are lenses that consist of a spherical and cylindrical surface. Spherocylindrical lenses were the first lens form used to correct ocular astigmatism.

Commitment to innovation and customization in optical lens technology goes a long way. Tailoring lens designs specifically to the nuanced requirements of a wearer can result in lenses that exceed expectations in performance and quality. Achieving optimal visual clarity involves technologies that achieve the following results:

With a meniscus lens, both sides of the lens have a curve, but the curves bend opposite each other. One side will bend outwards, and the other will bend inwards (as opposed to biconvex, where both sides bow out, and biconcave lenses, where both sides bend inward). When looking at the lens, a positive meniscus lens is thicker in the center and thinner at the edges. A negative lens is the opposite and thinner in the center of the lens while thicker at the surrounding edge. The difference comes from addressing varying spherical aberrations.

Optical lens manufacturers can create custom lenses that fix nuanced and specific visual issues by blending various technologies, shapes, functions, and forms. The most common types of lens designs for vision issues are:

In its simplest form, an optical lens focuses or disperses beams of light through refraction. The oldest optical lens discovered, the Nimrud lens, dates back to eighth-century Assyria. The Assyrians crafted this ancient lens from rock crystal with similarities to modern lenses. The discovery of the Nimrud lens as an early precursor to contemporary eyewear reveals the advanced technology of the Assyrians and the longstanding human endeavor to manipulate light and enhance vision through optical lenses. Fortunately for today's wearers, advancements in optical science have significantly broadened the scope and efficacy of lenses.
