Asphericlenses advantages disadvantages

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.

Learn what you need to know about bifocals and trifocals, including occupational multifocal lenses for work and play, plus optional lens coatings.

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

Learn how prism glasses correct double vision. They affect how light reaches the retina, look like regular glasses and are usually covered by insurance.

Glasses for astigmatism are among the most popular treatment methods. Special lens brands and features are available to correct astigmatism.

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.

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.

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.

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.

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

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.

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.

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

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.

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.

Hyperion Optics has become a influential cylinder lens supplier after so many years development. There is a wide range of optics of cylindrical lenses in ...

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 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.

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.

Lenticular lenses have large magnification in the central portion, aiding in the correction of conditions that cause very blurry vision.

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.

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.

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