    Product Detail

    Historical Background

    The concept of progressive multifocal lenses was first proposed by Owen Aves in 1907, inspired by the shape of an elephant's nose. This type of lens has a high usage rate in Europe and America, and has gradually become popular in China in recent years.

    Through the above description, we can comprehensively understand the definition, characteristics, usage methods, and historical background of progressive lenses, which can help us better choose and use this vision correction tool.

    Characteristic

    Multi focal design:

    Progressive lenses have multiple focal points on the same lens, gradually changing from the far zone to the near zone, avoiding the obvious boundary lines of traditional bifocal lenses and reducing visual jumping and wearing discomfort.

    progressive-series-optical-lens-5
    High comfort:

    The wearer does not need to frequently adjust the focal length, reducing visual fatigue and eye adjustment burden, and improving the comfort of wearing.

    progressive-series-optical-lens-6
    Wide applicability:

    Suitable for people with vision problems such as farsightedness, myopia, and presbyopia, especially for middle-aged and elderly people over 40 years old, students who use their eyes for a long time, and white-collar workers.

    Usage and Precautions

    Adaptation period:

    It may take about a week to adapt to wearing progressive lenses for the first time, during which you may feel dizzy. It is recommended to start with static activities and gradually transition to dynamic activities.

    Correct use (Long distance zone):

    When driving or looking, slightly retract your chin and keep your head level, looking through the center of the lens slightly higher.

    progressive-series-optical-lens-8
    Mid distance zone:

    When viewing a computer screen, look slightly lower in the middle of the lens and adjust the neck position slightly until the image is clear.

    Close range area:

    When reading a newspaper, place it in front of you, slightly extend your chin forward, and adjust your gaze downward to the appropriate mirror area 4.

    Avoid using blurry areas:

    The areas on both sides of the lens are areas of varying brightness, and the field of view is relatively blurry. It is recommended to rotate the head and eyes as much as possible for clear viewing.

    Frequently Asked Questions

    What is the historical origin of progressive multifocal lenses?
    The concept of progressive multifocal lenses was first proposed by Owen Aves in 1907, inspired by the shape of an elephant's nose. Today, they are widely used in Europe, America, and increasingly in China.
    What makes progressive lenses different from traditional bifocals?
    Progressive lenses have multiple focal points on the same lens that gradually change from the far zone to the near zone. This eliminates the obvious boundary lines found in traditional bifocals, reducing visual jumping and eye discomfort.
    Who are progressive lenses recommended for?
    They are ideal for people experiencing vision issues like farsightedness, myopia, and presbyopia. They are highly recommended for middle-aged and elderly people over 40, white-collar workers, and students who spend long hours focusing.
    How long does it take to adapt to progressive lenses?
    It typically takes about a week to adapt to wearing progressive lenses for the first time. Some mild dizziness is normal during this period. It is best to begin with static activities before moving on to dynamic ones.
    How do I look through the different zones of progressive lenses?
    Look through the upper center for long distances (chin slightly retracted), the middle area for mid-distances like computer screens, and the lower area for close-up reading (gaze adjusted downward).
    Why is my vision blurry when looking through the sides of the lenses?
    The areas on both sides of progressive lenses are peripheral aberration zones where the focus varies, leading to blurriness. To see clearly, turn your head and face the object directly rather than just moving your eyes.
