    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.

    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 origin of progressive multifocal lenses?
    The concept was proposed by Owen Aves in 1907, inspired by the shape of an elephant's nose. They are highly popular in Europe and America and are now increasingly adopted in China.
    How do progressive lenses differ from traditional bifocals?
    Unlike traditional bifocals that have distinct lines dividing the fields of vision, progressive lenses feature a gradual transition from far to near focal points on a single lens. This design prevents visual jump and minimizes wearing discomfort.
    Who can benefit from wearing progressive lenses?
    They are suitable for individuals with vision issues like myopia, farsightedness, and presbyopia. They are particularly beneficial for adults over 40, students, and office workers who experience prolonged eye strain.
    How long is the typical adaptation period for new wearers?
    It usually takes about a week to adapt. First-time wearers might experience mild dizziness. It is best to start using them during sedentary tasks before moving on to dynamic activities like walking or driving.
    How do I look through the different zones of a progressive lens?
    Use the upper portion of the lens for distance viewing (keeping your head level). Use the middle portion for intermediate tasks like computer screens. Look through the bottom area of the lens for close-up reading.
    Why does my vision seem blurry when looking through the sides of the lens?
    The outer edges of progressive lenses are peripheral distortion zones with varying optical strength, which naturally causes blurriness. To see clearly, turn your head and eyes toward the object rather than looking out of the sides of the glasses.
