Feature
Differences.
 |
Modern progressive lenses, on the other hand, have a smooth and consistent gradient between differing lens powers. In this sense, they can also be called “multifocal” or “varifocal” lenses, because they offer all of the advantages of the old bi- or trifocal lenses without the inconveniences and cosmetic drawbacks.
|
"No-line bifocals"
Progressive lenses, sometimes called "no-line bifocals," eliminate the visible lines of traditional bifocals and trifocals and hide the fact that you need reading glasses. With progressive lenses, no one has to know whether you're wearing glasses just for fashion — or because your arms have "grown too short" for you to see up close. |

Advantages
 | ● Each lens is customized exactly to the position of the wearer’s eye, taking into account the angles between each eye and the surface of the lens when looking in different directions, providing the sharpest, crispest image possible, as well as enhanced peripheral vision.
● Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision. | |
