Bifocal Lenses
——Seamless Transition Between Near & Far Vision for Daily Comfort
As people age, they not only face myopia problems, but also need to deal with presbyopia symptoms. As an innovative vision correction product, bifocal glasses can meet the needs of both myopia and presbyopia, providing people with a more convenient and comfortable visual experience.
What Are Bifocal Lenses?
Bifocal lenses are for people who need both distance and near vision. Unlike single-vision Eyeglass Lenses, bifocal lenses have two powers, with the top of the lens used for distance and the bottom of the lens to aid reading or close work.
Advantages and disadvantages of bifocal lenses
Advantages: One lens can be used for multiple purposes, avoiding frequent replacement of glasses.
Disadvantages: There is a jump phenomenon (prism effect) when switching between far and near vision; it is obviously different from ordinary lenses in appearance; the field of view is small.
Applicable groups
1. Office workers: For people who work in front of computers for a long time, bifocal lenses can meet the needs of both near and far distances, reduce eye fatigue and improve work efficiency.
2. Elderly people: As they age, they often face the problems of myopia and presbyopia. Bifocal lenses can help them better adapt to the visual needs of different distances and improve their quality of life.
3. Students: Students often need to frequently switch between close-up reading and long-distance viewing. Bifocal lenses can provide them with a convenient and comfortable visual experience and reduce eye pressure.
In general, bifocal lenses integrate the functions of correcting myopia and presbyopia into one through the optical design of lens partitions, taking into account both convenience and aesthetics.
