Bifocal Contact Lenses from Our Optometrist in Manchester
You may have had great luck correcting simple nearsightedness or farsightedness with contact lenses for many years, but times change, and so do eyes. If you're now struggling with a focus issue called presbyopia, you'll need additional help to bring both near and distant objects into focus. Does that mean you have to switch to bifocal eyeglasses? If you're a patient at Prudhomme Vision, the answer is no. Our Manchester optometrist can fit you with bifocal contact lenses that can perform that kind of correction.
How Do Bifocal Contacts Work?
Why do so many people need some type of multifocal lenses? Once you pass the age of 40, the lenses of your eyes become more and more resistant to the tiny muscles that control their focus. Typically, this change means that your ability to see near objects or book text clearly is reduced. If you already have a refractive error such as nearsightedness that makes distant objects blurry, you now need two different kinds of correction at the same time. Bifocal eyeglasses solve this problem by placing a near-vision segment toward the bottom of the lens, and correcting for distance vision toward the top. Progressive lenses operate on the same principle, but with a single, smoothly-blended gradation stretching from the top of the lens to the bottom.
Bifocal contacts offer two separate corrective fields just as eyeglasses do. They can have this effect in one of three possible ways. Segmented contacts use the same arrangement as bifocal eyeglasses, with a separate near-vision segment in the bottom half of each lens. Concentric contacts place the distance and near fields in alternating concentric rings, with the eye instinctively "finding" the right correction for the right situation. Aspheric contacts act like progressive eyeglass lenses, with the near-vision correction at the center gradually shifting through an intermediate zone to a distance correction toward the rim of the lens.
From the Contact Lens Exam to the Finished Contact Lenses
The first step in obtaining any type of bifocal contacts is to undergo both vision testing and a contact lens exam. The vision exam gives us your corrective prescription, while the contact lens exam allows us to measure your pupils and corneas so your bifocal contacts will fit properly. They also help us factor in any other health or lifestyle considerations that might affect the choice of the final product.
