Understanding Indoor Living Distance
The typical living distance for many people doing indoor activities is around 5 meters.
Additionally, those spending long periods indoors often focus on objects at intermediate and near distances.
When using bifocal glasses, the eyes can become strained from constantly looking through the narrow intermediate and near viewing zones for extended periods.
Bifocals are convenient glasses because users can see both far and near objects, but they are not all-purpose lenses.
This means that within indoor spaces, the viewing range is more important than viewing distance.
Lenses that allow users to see a wide range within indoor spaces help improve quality of life.
You can have convenient glasses tailored to what you want to see indoors.
For hours spent at home or in the office, where people frequently use smartphones and personal computers, watch TV, or cook, multifocal lenses for intermediate/near vision are suitable. These lenses offer a wide field of view from intermediate to near distances.
Intermediate/near multifocal lenses are designed to reduce far vision focus and widen the intermediate viewing area, providing a broad visible range that allows users to comfortably see their indoor environment.
These lenses help reduce unnecessary searching for clear viewing zones and can decrease eye strain and fatigue.
