Double asphericity is not a new concept. The benefits of aspheric lenses Laser Optics - White Light Laser and its Application . In addition to spherical aberration correction, aspheric lenses are very powerful in correcting off-axis/ field dependent aberrations such as field curvature, astigmatism, and distortion. Aspheric lenses are flatter, thinner and lighter in weight than the conventional "best form" lenses. You can also go for double Aspheric lens that has more advantages than single aspheric. LE1VO20. No charge . Double Aspheric glass optics provide Clear imaging . Aspheric lenses have a slimmer profile for virtually all prescriptions, but the difference is especially dramatic in lenses that correct high amounts of farsightedness. What is a Bandpass Optical Filter? The Wynne-Dyson projection lens is a classical design for unity magnification projection system.

LENSES . -Unique glass surface curves and coating minimize distortion and reflections. The surfacing is on both sides of the lenses which make them more flat that regular lenses and thinner . The GOV® M4 lens is a double reverse geometry lens with the aspheric alignment zone, which is applied to every GOV® design for better centration, makes M4 unique among similar designs. High magnification provides excellent views of the optic. SEIKO developed the world's first double-aspherical lenses to minimize distortions and improve peripheral vision right up to the edge of the lens. Deluxe Progressive . Brand : Dr.Onic Features & Benefits of 20D Aspheric Lens :- Double aspheric glass optics provide Clear imaging. High magnification provides excellent views of the optic. Aspheric lenses—those de-signed to avoid adding positive spherical aberration to an optical system—are in wide use in today's world. Conventional spherical lenses with a strong prescription for farsightedness cause unwanted magnification. High magnification provides excellent views of the optic. If you're strongly farsighted (+) double aspheric lenses will reduce lens-bulk in the centres of your lenses due to their convex profile. Aspheric lenses are more prevalent in high indexes such as 1.61, 1.67 and 1.74 designed to reduce thickness for strong prescriptions. High magnification provides excellent views of the optic disc and macula. To determine if they're right for you and if you'll get the most out of your investment, let's review the characteristics of 1.74 high index lenses and the effects of aspheric lenses.

This can be done on one side of the lens (Aspheric), or both sides of the lens (Double Aspheric) - the latter double option being the thinnest and lightest. Benefits of Aspheric Lenses It displays a flatter front curvature and excellent visual quality. Aspheric lenses use varying curvature on the front of the lens to reduce bulk, whilst double aspheric lenses do this on both the front and the rear of the lens. These benefits will increase the higher the index lens option selected. This combination results in flat, thin and light lenses which provide excellent visual quality. There is a number"2" etched on the side opposite the II in the Volk II name. Double-aspheric free-form design lenses are thinner & lighter with flatter curves on both sides.
