HOME >> Progressive lenses for short and intermediate distances developed with a new concept

These are progressive lenses that offer comfortable vision at near and slightly distant objects.

They are called Resonas Presso.

The wide type, which focuses on wide vision, and the long type, which focuses on depth are both for short and intermediate distances. Their crossed designing allows their progressive corridors (the distance from the power for far distances to the starting of the power for short distances) to be selected by 2×2 from two types (23 mm and 21 mm) with PRESSO, and 2×3 from three types (23 mm, 22 mm, and 21 mm) with PRESSO WS. Therefore, the range of suitability to differing usage environments among each and every user as well as their frame designs has been broadened.

We also took on a different approach from designs based on neuroscience that are pleasing to the brain in the conventional Resonas series to evaluate and increase performance in peripheral vision based on the latest findings in neuroscience concerning how the brain interprets objects when spectacle lenses are worn. This is how we have adopted a completely new concept to offer levels of clarity and comfortable fitting that exceed those of simple viewing.

Below are reports based on actual experiences.

We have prepared four frames of the same shapes in order to compare how the four PRESSO 2×2 types fit under the same conditions. We will also make comparisons between types such as those for short and intermediate distances, and those for short distances.

Short distances: Objects such as documents and computer screens in front of you

Here is a description based on the fact that all four offer wider vision than the types for both short and far distances.
As you may know, the wide type makes vision when looking at documents and newspapers wider than when using the long type.
The wide type surprisingly offers a sharpness that was never experienced before.
You may wonder if this vision is a result of better peripheral vision.
Next, we opened up a newspaper.
My vision of it was also wide with the long type.
The wide type offers wider vision, but please be assured that those who try only the long type for the first time should be able to enjoy wider vision than with progressive lenses that they had been using in the past.
We next looked at a computer monitor, but honestly could not see any differences among the four because there is a limit to how wide computer monitors can be.

Intermediate distances: Objects such as posters two meters-away

By turning my face directly at objects and changing the part of the lenses I looked through by slightly moving my jaw up and down, I was able to find their focal points and see them the same way.
Vision was wider with the wide type even at this distance.
At this distance, any one of the types made people’s faces look clearer than with the type for short and far distances.

Long distances: Objects such as calendars and people’s faces fifteen meters-away

People’s faces and numbers on calendars can be identified with any of the types even at this distance.
Vision with the wide type seems a little more blurry and the long type does not offer as much clearness as the type for short and far distances does, but there are no problems with it during indoor use.
However, please do not use them for driving even they provide a certain degree of vision because they are lenses that are exclusively for indoor use.

Comparisons between products such as conventional lenses for short and intermediate distances (Indoor) and lenses for short distances (Largo)

The main difference between the conventional lenses for short and intermediate distances and the long type is width in vision.
You can see the difference by facing directly at an object and gradually looking diagonally.
A comparison between lenses for short distances and a wide type were made with a newspaper fully spread out.
Both made reading the newspaper easy, but the lenses for short distances is recommended for those who work with their hands for long periods of time because the newspaper looked slightly larger with them.

Overall

PRESSO comes in two types of progressive corridor lengths and we contacted the developer to ask how to select from among them because it is hard to tell the difference when they are the same type. We were told that it is best to match the progressive corridor with that of the progressive lenses because the position where you see objects right in front of you will be the same. Basically, the 21 mm type is 10 mm above and 11 mm below the eyes and the 23 mm type is 10 mm above and 13 mm below the eyes. For example, I normally use the Resonas Fit with a progressive corridor of 13 mm as the progressive lenses, but I can see objects in front of me with the same position as that with progressive lenses for short and far distances when using the Presso if it is a 23 mm type. So what about people who do not use progressive lenses? Please note that they feel easier to get accustomed to as the progressive corridor is longer. When it comes to selecting from among long types and wide types; wide types are recommended for those who do much deskwork without giving it much thought, and long types are recommended for those who often look at television screens and monitors that are slightly distant or walk around a lot indoors. We hope that you can use them more comfortably by switching them with your current progressive lenses as the situation demands while enjoying the benefits of their usability that equals that of those for short distances as well as being able to see every detail when indoors.
