About Progressive Lenses
Our progressive lens products are no-line bifocal lens with seamless progression from far to near fields of vision. The magnifying power changes from the top half of the distance-field lens (clear lens with no magnifying power) to the lower half of the near-field lens (magnifying power) by your viewpoint when you see objects from top to bottom. However, due to the structure of the lens, there are distortions in the peripheral vision (what you see on the edges when looking ahead) where the visibility change in clarity and position. Before you purchase this product, please understand that these features may cause discomfort to visibility for first time users.
※These lenses do not correct near-field vision or astigmatism.
We only offer custom orders for vision corrected lenses in Japan.

Q & A
Bifocal progressive lens
-
I have difficulty seeing my feet. What should I do?
-
The lower part of the lens has a near power, so it will be blurred when you look at your feet. So when you look at your feet, always pull your chin and look at the top of the lens.

When I look sideways, the scenery looks blurry. What should I do?

The periphery of the lens is difficult to focus and may appear distorted. You can reduce discomfort by consciously pulling your chin and moving your face left and right.
