    When it comes to eyeglasses, a +1.00 prescription refers to the power of the lens. This measurement is essential to ensure that your eyeglasses provide the necessary correction for your eyesight. In this article, we will explore what +1.00 means for glasses, and how it is used to correct mild farsightedness.

    What Does +1.00 Mean?

    The power of an eyeglass lens is measured in diopters (D), which refers to the lens's ability to bend light. The higher the diopter number, the greater the lens's power, and the more significant the correction it provides. A +1.00 lens has a power of one diopter, which means that it can bend light by one unit of refractive power.

    A +1.00 lens is a low power lens used to correct mild farsightedness, also known as hyperopia. Farsightedness is a common refractive error that affects many people, particularly as they age. With farsightedness, distant objects can be seen more clearly than objects that are up close. This is because the eye's focusing power is weaker than it should be, and light rays are focused behind the retina instead of on it.

    A +1.00 lens can help to bring close-up objects into focus, making them appear clearer and easier to read. This can be particularly helpful when performing tasks that require close-up vision, such as reading or using a computer.

    How Is +1.00 Used in a Prescription?

    When you receive a prescription for glasses, it will typically include several values that determine the lens's power and other characteristics. These values are determined through an eye exam and consultation with an eye care professional, and will vary based on your individual eyesight needs. A +1.00 prescription may be part of this larger prescription, depending on your eyesight needs.

    A prescription typically includes the following values:

    • Sphere (SPH): The spherical power of the lens, measured in diopters. This value indicates the lens's power for correcting nearsightedness or farsightedness. A +1.00 prescription would be listed as "+1.00" in the sphere column.

    • Cylinder (CYL): The cylindrical power of the lens, measured in diopters. This value indicates the lens's power for correcting astigmatism. If you do not have astigmatism, this value will be "0.00."

    • Axis: The orientation of the cylindrical power, measured in degrees. This value indicates the angle of the lens that corrects astigmatism. If you do not have astigmatism, this value will be "0."

    • Pupillary distance (PD): The distance between your pupils, measured in millimeters. This value indicates the distance between the center of each eye, and helps ensure that your glasses are properly aligned with your eyes.

    If your prescription includes a +1.00 value in the sphere column, it means that you have mild farsightedness, and the lens's power will help bring close-up objects into focus. This can make reading and other close-up tasks much easier and more comfortable.

    What Types of Lenses Are Available in +1.00?

    There are several types of lenses available in a +1.00 prescription, depending on your needs and preferences. These include:

    • Single vision lenses: These lenses have a uniform power across the entire lens, and are used to correct nearsightedness, farsightedness, or astigmatism. Single vision lenses are often used for reading glasses or for people who need correction for distance vision.

    • Bifocal lenses: These lenses have two distinct areas of power, with a larger area for distance vision and a smaller area for near vision. Bifocal lenses are a common option for people who need correction for both distance and close-up vision, as they allow for seamless transition between the two.

    • Progressive lenses: These lenses are similar to bifocal lenses but provide a more gradual transition between the different powers. This can provide a more natural viewing experience and can be a good option for people who need correction for multiple distances.

    • Aspheric lenses: These lenses have a flatter shape than traditional spherical lenses and can provide clearer vision, particularly at the edges of the lens. Aspheric lenses can be a good option for people who have a high prescription or who want a more lightweight lens.

    • High-index lenses: These lenses are made from a material that is denser than traditional plastic lenses, which allows for a thinner and lighter lens. High-index lenses can be a good option for people with a high prescription, as they can reduce the thickness and weight of the lenses.

    When choosing your glasses, your eye care professional can help you determine which type of lens is best for your needs and preferences.

    How to Choose the Right Frame for Your +1.00 Glasses

    In addition to choosing the right lenses, it's also important to choose the right frame for your glasses. The frame you choose can affect the fit, comfort, and style of your glasses.

    When choosing a frame for your +1.00 glasses, consider the following:

    • Frame size: Choose a frame size that fits your face and provides a comfortable fit. The frame should not be too tight or too loose, and should sit comfortably on your nose and ears.

    • Frame shape: Choose a frame shape that complements the shape of your face. Different frame shapes can accentuate different features and create a different look.

    • Frame material: Choose a frame material that fits your lifestyle and preferences. Frames can be made from a variety of materials, including metal, plastic, and titanium.

    • Style: Choose a style that fits your personal style and preferences. There are many different styles of glasses available, from classic to trendy, so take the time to find the perfect pair for you.


    A +1.00 prescription is a common prescription for reading glasses and mild farsightedness. It indicates the power of the lens and can help bring close-up objects into focus, making them easier to read and see. When choosing glasses with a +1.00 prescription, it's important to consider the type of lenses and frames that best fit your needs and preferences. With the right glasses, you can improve your eyesight and enhance your style and comfort.
