This is advice for those who have had progressice lenses made in the past but do not use them as they were difficult to get accustomed to.

To be specific, there were those who;

  • felt lightheaded, dizzy, and nauseous
  • find it frightening to glance to the side when driving because it looks fuzzy or distorted
  • do not feel satisfied with them because vision is narrow
  • become tired when reading books, working with their hands, or using computers

There are reasons behind all of these situations, which can be better understood by just slightly changing the way you use your lenses or how you see through them.

【The structure / layout of an general type progressive lens】

  • The power of progressive lenses is changed in the direction from above to below so they are convenient in that they let you see everything from far distances to the area right in front of you.
  • In order to find power that is suitable for vision from far to short distances in a vertical direction in the central part of a single lens anticipating the movement of the eyes, there has to be swaying and distorted areas in the surrounding part where the power is not stable.

【Causes of discomfort and measures against it】

Those who use progressive lenses for the first time receive messages from their brains that they are seeing differently no matter how well the lenses have been designed for reduced sways and distortions. This is because they are lenses with powers that change. However, making small adjustments in how they are used can make them easier to get accustomed to and use.

1. You feel lightheaded, dizzy, and nauseous. It is also hard to climb stairs.

The lower parts of the lenses have powers for short distances of about 30 to 40 centimeters in front of the user, but this is the part that user see through when glancing downward at the floor only with the eyes when standing.
This is the same as looking down at the floor through magnifying glasses while standing, which causes lightheadedness.
Looking through the center of the lens is the best way to reduce such discomfort.
In other words, it is good to pull your jaw back further when looking down at the floor.

2. It is difficult to drive because sights such as the side mirror and nearby scenery look blurry

It is difficult to attain focus and vision is blurry and distorted when looking to the side because we tend to see through the surrounding parts of the lenses where the power is not stable.
Therefore, you can see through the stable part of the lens by slightly turning your jaw further toward the location you are looking at in such cases.
By remembering to turn your face left and right more than usual, the spot you are looking at will be a little more inward and you can feel less discomfort as the power you use is more stable.

Progressive lenses, which incorporate neuroscience technology, are designed to reduce such discomfort as well as stress felt by the brain, but they can still be uncomfortable at first.
However, it is our hope that you use them comfortably while keeping the points above in mind as they are extremely easy to get accustomed to and use.
