In this article, you will learn about the differences in Kodak progressive lenses. This article focuses on the differences in lens designs and in which case you would benefit from one of those specific lens types. First of all, in the list below you can see the whole options of progressive lenses from Kodak:
- Kodak Unique II HD Lens
- Kodak Easy Lens
- Kodak Precise Digital Lens
- Kodak Concise Lens Digital Lens
- Kodak Precise Lens
- Kodak Concise Lens
The differences in those progressive lens designs are found in the ability to fine-tune them to your needed prescription. When the testing frame sits in your face the lenses have a certain distance to your eyes and are sitting at a certain tilt in front of your eyes. This position from the testing frame is not the same as the position of wear with the frame you choose in the end.
With a high-end lens like the Unique HD Lens the parameters that describe the position of wear can be used in order to fine-tune the lenses to your needs. For you, as a user, this means a bigger clear field of view can be experienced as well as a clearer image in general.
This article is written from the higher-end lens models to the less price intense ones. Even though you may not think about getting the higher-end lenses to read the section too to see where the differences can be found.
Kodak Unique II HD Lens
The Kodak Unique II HD Lens is the top is a high-tech progressive lens. For this progressive lens design the following parameters need to be measured:
- Shape of the frame
- Individual Inset
- Height for the left and right eye
- Vertex distance (optional)
- Pantoscopic tilt
- Wrap angle
With all those information the blurry areas in this progressive lens can be effectively minimized. For example, when Kodak knows how the shape looks like and where you will look through the lenses they can position the blurry fields of view so they are as minimized as possible. Having an individual Inset is always a great idea when choosing progressive lenses. This parameter makes it possible to position the reading area in different spots for the left and right eye.
Think about it most people have a face shape that is not symmetrical. Usually one has a slightly closer distance to the nose compared to the other eye. So when most people look at something to read their eyes would benefit from a differently placed reading zone because it fits the asymmetrical position of their eyes. The results are bigger reading zones and a more relaxed vision.
The same is true when the angles are measured in which the lens is tilted or wrapped in front of your eyes. This data minimizes blur effectively and makes the Unique II HD Lens Kodak’s top progressive lens. It is also the only progressive lens design which uses individual data.
This lens is great for people who have higher Add values than +1.75D and or higher prescriptions than 4 diopters. When you buy a more extravagant frame that sits more tilted in your face this progressive lens also might be beneficial to you.
Kodak Easy Lens
The Kodak Easy lens is as the lens design described above a back surface progressive lens. This lens design leads to a little bigger field of view. Due to the fewer parameters which will be used to produce the lenses the Easy Lens will give you smaller clear fields of view compared to the Unique II HD Lens.
When the Add value is lower than 1.75D this does not have to be an issue. But when you need a higher reading power (Add value) the areas you can use to read clearly get smaller. This is why it gets more important to choose a better lens design with the increasing reading power.
The Kodak Easy lens is available in three different corridor lengths. It can be therefore fitted to a smaller as well as to a bigger frame.
Kodak Digital Precise Progressive Lens
The Kodak Digital Precise lens is also a back surface progressive lens made with free form technology. This lens again has slightly fewer options. It is only available in one corridor length which is 19mm.
While a longer corridor leghorn is great because it makes the reading area bigger this lens might be less suited for people with an uneven prescription for their left and right eye. This uneven prescription is called anisometropia and a shorter lens design would work better with an uneven prescription.
One of the lenses that might work better will be described in the paragraph below.
Kodak Concise Digital Lens
This progressive back surface lens design is ideal for people who have an uneven prescription and do want a less price intense option. This lens design works well with wearers of different lens powers for each eye because of the sort corridor.
The wearer of the concise digital lenses does not have to look down as much in order to get maximum reading support out of the lower part of the lenses. This reduces the side effects of differently moving images for each eye.
This lens just needs 15mm of space between the point you are looking through eh lens when looking straight ahead measured down to the lower part of the frame.
What Distinguishes the Digital Concise and Precise Form the Precise and Concise Without the Digital?
The term digital here is used to describe the free from technology. In combination with the free form technology, the described progressive lens designs described above are all made with a progressive back surface. This increases the field of view a little but minimizes the magnifying effects. In general, this is a good thing. But when people really like their front surface progressive lenses they might miss the magnifying effects with more modern lens designs.
The lenses without the digital are conventionally made and have therefore a slightly smaller clear field of view. When people have higher prescriptions in some cases it makes sense to switch back to a simpler lens design like this and things turn out great again because of the slightly increased magnifying effect.
This is it. That was my short overview of the progressive lenses from Kodak. I hope you found the information you were looking for on progressive lenses.
I wish you great day.
