Abrégé

Conventionally, eyewear is rated in terms of its absorption coefficient (sometimes called the optical density (OD)) or the protection that it provides from ultraviolet (UV) radiation, which can damage the eye at high enough power levels. Infrared (IR) radiation can also damage the eye, but IR damage tends to occur at a much slower rate than UV-induced damage. Rating eyewear in terms of protection from IR radiation and/or in terms of a maximum safe exposure duration (SED) to IR radiation improves consumers' ability to protect themselves from IR radiation. In addition, eyewear rated for more IR protection or longer SED may still provide excellent vision thanks to coatings that reflect or absorb IR light and transmit visible light.

Abrégé

An ophthalmic single vision lens is presented, which is configured in accordance with original prescription parameters for vision correction of a patient. The lens has an aspheric modified surface such that as worn orientation of the lens corresponding to a relatively small physical pantoscopic tilt Ti provides visual quality corresponding to a substantially spherical lens surface having an optical power of the original prescription and orientation with simulated pantoscopic tilt T2 significantly higher than the physical pantoscopic tilt Ti, while maintaining the original prescription parameters within the aspheric modified surface.

Abrégé

An ophthalmic lens is presented being configured for a user's prescribed optical power P0 for far vision correction. The lens comprises: a fitting position; a first region corresponding to a far measuring position having the prescribed optical power P0 a second region corresponding to a near measuring position. The lens is configured with an optical power addition profile such that an optical power, Pƒ, at the fitting position, located at a distance D1 not exceeding 10 millimeters below the far measuring position, is different from the optical power P0 by di, being 0.3D≤di≤0.8D (D is diopter). The optical power addition profile thereby providing an improved intermediate distance vision of the lens.

Abrégé

Various embodiments disclose a quasi progressive lens including a first optical zone capable of providing distance vision, a second optical zone capable of providing near vision and a transition zone connecting the first and second optical zones. Physical dimensions (e.g., length and width) of the transition zone are adjusted to increase the size of the second optical zone in comparison to progressive lenses and to reduce residual cylinder power and aberrations along the convergence path in comparison to bifocal lenses.

Abrégé

Ultraviolet (UV) radiation can harm the eye. Fortunately, a spectacle lens can be coated with a UV anti-reflection (AR) coating to reduce the amount of UV radiation incident on the eye. If the AR coating is on the back side of the lens (the convex surface closest to the eye), the AR coating will reduce the amount of UV light that is transmitted through the lens to the eye. It will also reduce the amount of UV light that is reflected off the back side of the lens toward the eye. The AR coating may include five or more alternating layers of silicon nitride and silicon dioxide or other suitable dielectric materials. It can be sputtered onto the back side of the lens as part of an on-block manufacturing (OBM) process while the ophthalmic lens blank is still attached to the block, before the ophthalmic lens blank is removed and edged.
