1.56 Progressive Multifocal HMC Optical Lens

Short Description:

How Do Progressive Lenses Work?

Progressive lenses have zones meant for close-up, intermediate, and distance vision. These zones blend into one another, so the change in power is—you guessed it—progressive, rather than abrupt.

Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision.

Progressive lenses sometimes are called "no-line bifocals" because they don't have this visible bifocal line. But progressive lenses have a significantly more advanced multifocal design than bifocals or trifocals.
Premium progressive lenses (such as Varilux lenses) usually provide the best comfort and performance, but there are many other brands as well. Your eye care professional can discuss with you the features and benefits of the latest progressive lenses and help you find the best lenses for your specific needs.


What are progressive lenses?

Progressive lenses are no-line multifocal eyeglass lenses that look exactly the same as single vision lenses. In other words,
progressive lenses will help you see clearly at all distances without those annoying (and age-defining) "bifocal lines" that are
visible in regular bifocals and trifocals.

The power of progressive lenses changes gradually from point to point on the lens surface, providing the correct lens power for
seeing objects clearly at virtually any distance.
Bifocals, on the other hand, have only two lens powers — one for seeing distant objects clearly and a second power in the lower
half of the lens for seeing clearly at a specified reading distance. The junction between these distinctly different power zones
is defined by a visible "bifocal line" that cuts across the center of the lens.


Progressive Lens Benefits

Progressive lenses, on the other hand, have many more lens powers than bifocals or trifocals, and there's a gradual change in power from point to point across the surface of the lens.

The multifocal design of progressive lenses offers these important benefits:

* It provides clear vision at all distances (rather than at just two or three distinct viewing distances).

* It eliminates bothersome "image jump" caused by bifocals and trifocals. This is where objects abruptly change in clarity and apparent position when your eyes move across the visible lines in these lenses.

* Because there are no visible "bifocal lines" in progressive lenses, they give you a more youthful appearance than bifocals or trifocals. (This reason alone may be why more people today wear progressive lenses than the number who wear bifocal and trifocals combined.)


--Hardness: One of the best quality in hardness and toughness, high impact resistance.
--Transmittance: One of the highest transmittance as compared with other index lenses.
--ABBE: One of the highest ABBE value providing the most comfortable visual experience.
--Consistency: One of the most reliable and consistent lens product physically and optically.

New anti-reflective coating


The new anti-reflective film layer has super anti-ultraviolet function, and can filter a large amount of stray light, enhance the imaging quality of the lens, and the imaging effect at night is better, which greatly improves the safety of night driving.

Scratches on lenses are distracting, unsightly and in certain conditions even potentially dangerous.
They can also interfere with the desired performance of your lenses. Scratch-resistant treatments toughen up the lenses making them more durable.
