Best Distance Design
Progressive Lens Example - Best Distance Design

We optimize your distance vision for the eyeglasses you use most for driving, going to the theater, or out-and-about town.


Best Intermediate Design (Computer Distance)
Progressive Lens Example - Best Intermediate Design

We'll emphasize on the intermediate distance on the pair of eyeglasses that you use most for working on the computer for extended periods of time on a daily basis.


Best Reading Design

We'll give you the widest reading area on the pair of eyeglasses you want to use for close up reading.

Lens Technology

We partnered with the leading lens manufacturer to develop our own free-form lenses, which combine the latest technology and an extremely competitive price point.
Because the design is custom created to 1/100th of a diopter in accuracy, it will result in a better visual experience. The optimization process automatically maximizes the corridor length of your progressive lens by taking into consideration the frame you've chosen and how the frame fits you. Every progressive lens we do for you is unique to the frame that holds it in place.


What is FREE-FORM

Digital Surfacing, Free-form, Direct Surfacing: It seems everyone has a different name for what amounts to the same process. They all simply refer to a more accurate method of creating a lens surface. Instead of conventional surfacing where a fixed curve lathe is used to create a simple surface, Free-form generators use a diamond-tipped point that can create any complex surface. The Free-form generator is so accurate that it only requires a small amount of polishing to then complete the optical surface, this ensures that the integrity of the lens design is maintained through the whole process.


The question now becomes what can you do with this higher degree of accuracy?



Adjust Corridor Lengths


With conventional progressives the design is already molded on to the front of the lens. Free-form allows the lens design to be created specifically for you and your frame, so the concept of long and short corridor designs can be taken away. Now the corridor will be adjusted based on nearly any fitting height requested. (keep in mind you can also request a shorter corridor regardless of the height to tweak the design for your preference.)



Correction for Oblique Astigmatism


As your eyes rotate away from the optical center in your lenses, you will experience cylinder at the periphery. By using advanced computer modeling at every angle away from the optical center, our advanced Free-form surface can correct that aberration. This can create perfect vision from edge to edge, especially in your distance area of your progressive lenses. This is the primary benefit of Free-form, effectively making almost the whole lens the sweet spot.



Position-of-wear Compensation


 Free-form lenses also allow for the correction of additional parameters. POW compensation refers to the creation of an adjusted Rx that corrects for the discrepancy between the angle and position of the lenses in a phoropter and the lenses in your eyeglasses. The specific measurements are Panoramic Angle, Pantoscopic Tilt and Vertex Distance.

Base Curve Flexibility


By incorporating computer modeling and POW compensations, Free-from also allows you to move away from best curve fitting without sacrificing peripheral optics. Traditionally the front curve of a lens was chosen based on an attempt to create roughly a 6 diopter back surface, since the approximate rotation of the eye at a 12 mm vertex distance is a 6 diopter curve. This means that conventional lenses have only one ideal base curve for every prescription.  Free-form makes that less rigid because the compensation as the eye rotates away from the optical center can correct for the peripheral cylinder when accurate POW measurements are specified.

Customer Personalization


The newest level of customization available is based on your preferences and lifestyle. All progressives have to obey the same laws, which defines that the amount of unwanted cylinder in a design is based on the add power of the prescription. There are, however, subtle ways that the corridor can be adjusted within those laws. By incorporating different factors about how you want to use your lenses, the design can now be geared ideally for golf, shooting sports, card games, etc.....
