Aspherical lens

Advanced optical design technology allows aspheric eyeglass lenses to be made with flatter curves than conventional lenses, giving them a slimmer, more attractive profile.

Creating the complicated curves used in aspheric lenses makes these advanced lenses a bit more expensive than conventional lenses. But the outstanding cosmetic and visual benefits of these thinner, lighter lenses make them a good investment.

Since aspheric lenses are flatter and positioned slightly closer to the face than conventional lenses, some wearers may notice more reflections off the front and back surfaces of the lenses. For this reason, anti-reflective coating is highly recommended for all aspheric lenses.

Aspheric designs are available in single vision lenses for the correction of nearsightedness, farsightedness and astigmatism, and in progressive lenses, bifocals and trifocals for presbyopia. Although most aspheric lenses are made from high-index materials, they are available in regular plastic, too.

It also makes it possible for someone with a strong prescription to wear a larger selection of frames without worry of the lenses being too thick.

Eyeglass lenses that correct myopia (concave or "minus" lenses) have the opposite shape: they are thinnest at the center and thickest at the edge.

Whether you are nearsighted or farsighted, aspheric lenses are thinner and lighter and have a slimmer profile than ordinary lenses.

Aspheric lenses have a slimmer profile for virtually all prescriptions, but the difference is especially dramatic in lenses that correct high amounts of farsightedness. Lenses that correct farsightedness (convex or "plus" lenses) are thicker in the center and thinner at their edge. The stronger the prescription, the more the center of the lens bulges forward from the frame.

Conventional spherical lenses with a strong prescription for farsightedness cause unwanted magnification. This makes objects appear larger and closer than they actually are. And because this magnifying effect goes both ways, conventional lenses for farsightedness also give the wearer's eyes an unnaturally magnified, "bug-eyed" look.

For several reasons, frame selection is important with aspheric lenses. In general, the best-looking eyewear results when the frame is not overly large and when the eyes are centered in the middle of the frame opening. Your eye doctor or optician will help you select the best type of frame to complement your new aspheric lenses.

Though the slimming effect of an aspheric design is less dramatic in minus lenses, it still provides a noticeable reduction in edge thickness compared with conventional lenses for myopia correction.

Quality light diffuser panels are essential lighting tools for anyone looking to create professional quality lighting for photography and videography. Light diffuser panels help create even, diffused lighting that is flattering to the subject and enhances the overall quality of the final product without heavy edits. By softening harsh light and eliminating shadows, diffuser screens can produce a natural-looking illumination ideal for portraits, products, and video shoots. This makes light diffuser panels indispensable for achieving the perfect lighting in a variety of settings, from studio shoots to outdoor locations.

Aspheric plus lenses can be made with much flatter curves, so there is less bulging of the lens from the frame. This gives the eyewear a slimmer, more flattering profile.

We carry light diffuser panels, diffuser fabrics, and diffuser screens in a range of sizes, shapes, and styles for all types of lighting setups. Another important feature of these light diffuser panels is their portability and convenience. Made from lightweight materials, the diffuser fabrics and screens collapse into smaller shapes that are just as easy to take down and store as they are to set up.

Most aspheric lenses also are high-index lenses. The combination of an aspheric design with high-index lens materials creates a lens that is noticeably slimmer, thinner and lighter than conventional glass or plastic lenses.

Disadvantages ofasphericlenses

Aspheric lens designs, on the other hand, reduce or eliminate this distortion, creating a wider field of view and better peripheral vision. This wider zone of clear imaging is why expensive camera lenses have aspheric designs.

Light diffuser panels are compatible with various light sources, such as studio strobes, continuous lights, and speedlights. It's crucial to select the right light diffuser panel for your light source. Certain diffuser screens and fabrics are specifically designed to diffuse high-powered light sources, while others may block out weaker light more than desired. Similarly, some light sources may be too strong for less opaque diffuser fabrics.

Taking measurements for aspheric lenses requires greater care and skill on the part of the optician, but this requires only an extra minute or two.

Asphericlenses meaning

Conventional lenses have a front surface that is spherical, meaning it has the same curve across its entire surface, much like a baseball.

Conventional lenses for nearsightedness do just the opposite: They make things look smaller and give the wearer's eyes a small, "beady-eyed" appearance.

Aspheric lenses greatly reduce these undesired magnification and minification effects, so the world looks more natural to the wearer, and the wearer's eyes look more natural to everyone else.

With conventional lens designs, some distortion is created when you look away from the center of the lens — whether your gaze is directed to the left or right, above or below.

Aspheric lenses, on the other hand, have a more complex front surface that gradually changes in curvature from the center of the lens out to the edge.

Because aspheric lenses have flatter curves than conventional lenses, they fit closer to your face. This is a major benefit for anyone wearing a strong correction.

Light diffuser panels can help achieve an even distribution of light from LED lighting, which is prone to producing spots of highly focused light. LEDs are efficient and often adjustable, but light diffuser panels help achieve subtle effects that can enhance the quality of photos.
