What Are Multifocal Lenses?
Multifocal lenses go by several names such as: progressive lens, progressive addition lenses (PAL), progressive power lenses, graduated prescription lenses, and Varifocal lenses.Other than progressive multifocal lenses, we carry a wide variety of multifocal lenses including bifocal and trifocal line multifocal lenses. These lenses provides distance and near vision in one lens. The near vision correction of the lens is contained in a segment, often visible on the front of the lens. This segment provides the extra power necessary for you to read clearly. Bifocals and Trifocals are the traditional classic solution to presbyopia; and, as a line dividing the lens is visible, some patients feel bifocals are not as cosmetically appealing.
Why Are Multifocal Contact Lenses Necessary?
Eyes change throughout our lives, gradually losing the ability to focus on close objects. During our mid-forties, the lenses in our eyes become stiffer, and the muscles that control them change – which eventually causes blurred vision. This is called Presbyopia, and it happens to all of us. You’ll probably find yourself holding books, newspapers or product labels further away, or needing more light in order to read clearly. Multifocal lenses offer you a solution that will give you both good near and distance vision.
How the Multifocal Lenses Works
How your lens works depends on what your focal needs are. Some multifocal lenses are designed with bifocal elements– two distinct lens powers that accommodate for distance vision and near. Others have a multifocal design similar to progressive eyeglass lenses, that have a gradual lens power change to support a more natural visual transition from distance to close-up.
Multifocal lenses are characterized by a gradient of increasing lens power, added to the wearer’s correction for the other refractive errors. The gradient starts at the wearer’s distance prescription, at the top of the lens and reaches a maximum addition power, or the full reading addition, at the bottom of the lens. The length of the progressive power gradient on the lens surface depends on the refractive index of the lens, with a final addition power between 0.75 to 3.50 dioptres for most wearers. The addition value prescribed depends on the level of presbyopia of the patient and is closely related to age and to a lesser extent, existing prescription.
