Lenses for activities at work or home

Understand the indoor living distance.

The living distance of many people performing indoor activities is approximately 5 meters.
In addition, people living indoor for a long time frequently look at things at middle and near distances.
When bifocal lenses are used, the eyes are likely to get strained because they must continue to look at things through the narrow ranges of the middle vision and near vision areas for a long time.
Bifocal lenses are very convenient eyeglass lenses because the user can see all things at far and near distances, but they are not all-purpose.
This means that in indoor space, the breadth of the visible range is more important than the visible distance.

Eyeglass lenses through which the user can see a wide area in indoor space improve QOL.

You can have eyeglasses convenient for living according to what you want to see indoors.
For hours at home and in offices where people frequently use smartphones and personal computers, watch TV, or do cooking as main activities, progressive power lenses for middle/near vision with which the user can widely see things from the middle to near distances are suitable.
Progressive power lenses for middle/near vision are designed to have a reduced function for viewing far and a wider middle viewing area, offer a wide visible range, and enable the users to sufficiently see indoor space.
These lenses make the effort to find an easy-to-see area of the lens no longer necessary and can reduce stress and eye strain.

Countermeasures / Improvements

• We recommend progressive power lenses for middle/near vision that have a sufficient middle viewing area, which is insufficient on bifocal lenses, and a wide field of view for near vision.
• At an eyeglass store, receive a wearing test of progressive power lenses for middle/near vision to check how things look through them without fail.
  *When driving a car or riding a motorcycle, bicycle, etc., do not use progressive power lenses for middle/near vision. It is dangerous.
