No-Line Bifocals/Trifocals

Another term often referred as Progressive Lenses is "No-Line Bifocals" or "No-Line Trifocals", which eliminates the visible lines of traditional bifocals and trifocals and hides the fact that you need reading glasses. No one needs to know you're wearing glasses for fashion or your arms have "grown too short" for you to see up close.

Why Do I Need Progressive Lenses?

Once you reach the age of 40, give or take a few years, a person's vision gradually changes and increases over a five to seven year period and then it usually stabilizes. The gradual change is caused by the crystalline lens inside the eye to change shape. The changing shape of the crystalline lens allows one to focus from distance to near and back. Tiny attachments to the lens called zonules gradually lose their ability to cause the lens to change shape and hence to allow focusing at different distances. This is a natural maturing (aging) change and will happen to all of us.

Choosing the Right Progressive Lens

For all the powers of progressive lens to fit within a pair of eyeglasses the lenses use to have to rather large but that time has past. Here at SimplyEyeglasses.com, our optical lab provides and recommends three types of progressive lenses:

• Image Progressive - this lens is the least expensive but still its a very high quality progressive lens type can support a vertical height of a lenses as low as 28mm.
• Kodak Progressive - this is our middle tier progressive lens from a name you can trust, this lens can support a vertical height as low as 24mm.
• Kodak Unique Digital Technology - this is a digitally surfaced lens ( new lens design ) that is one of the top progressive lenses on the market, comparable to Varilux Physio 360. If you want better optics through the entire lens then this is the lens for you. It supports a vertical height of 23mm.

Kodak Unique Digital Technology

To further touch on the progressive lens type Kodak Unique, a good comparison in layman's terms would be the difference between a regular TV and an HD TV. Everything is clearer and sharper. Contrast sensitivity is improved therefore making night driving easier and better. Wider reading and intermediate areas are found and larger depth of field can be seen. Almost immediate adaptation occurs from patient feedback. If you cannot adjust to the typical progressive lens then you may want to try this one because we have seen in almost all cases a patient be able to adapt to this lens.

Adjusting to Progressive Lenses If you're new to progressive lenses it could take several days to a couple weeks to adjust.

You must learn to move your head to see things, you cannot simply keep your head straight and move your eyes because you'll be looking through a blurry part of the lens. As mentioned, it could take some time to adapt, one could experience dizziness and headaches during the time that you are adapting. Please call us to speak to optician or consult your eyecare specialist to get instructions on how to use progressive lenses.

With today's lens designs, nearly everyone can wear progressive lenses successfully especially the Kodak Unique Digitally Technology because its only been in rare cases a patient has not been able to adjust.
