If all refractive errors (aberrations in the eye structure that cause distorted vision) were as straightforward as nearsightedness or farsightedness, prescribing and creating corrective lenses would be a much simpler matter. But as your eye changes, you may develop several different types of refractive errors simultaneously — or you have been born with progressively worsening astigmatism that complicates your lens prescription. In the past, these issues might have confined your choices to eyeglasses. But here at Twelve Bridges Vision Care, we offer state-of-the-art multifocal contact lenses.
One of the most common vision disorders in individuals aged 40 and over is called presbyopia. As the lens of the eye ages, it becomes stiffer and less able to change it’s field of focus easily. This makes it harder and harder for you to read fine print or perform detailed work at close range. As a result, you may find yourself effectively nearsighted and farsighted at the same time. To make matters worse, tiny irregularities in the surface of your cornea may contribute additional distortion, a condition known as astigmatism. In the early days of contact lenses, it was impossible to create lenses that could correct for all these differences, and presbyopia sufferers had no choice but to wear eyeglasses. Today, however, modern contact lens design and fabrication techniques have made it possible for these small wonders to correct multiple fields of vision.
Multifocal lenses come in a variety of forms, but they all work very much like “progressive” multifocal glasses so popular among modern eyeglass wearers. Instead of sharp divisions between visual fields, these lenses feature gentle transition zones from one field to the next. For example, most multifocal lenses have the distance vision correction on the outside part of the lens, and then it “blends” toward the near vision correction at the center of the lens. Your brain then learns to see these fields as “normal,” choosing which one to use whether you are looking far away or close up.
Your Source for Multifocal and Hard-to-fit Contacts
If you can’t get used to having multifocals in both eyes, you can try monovision (the use of a distance vision correcting lens in one eye, and a reading vision correcting lens in the other eye). Our eye doctor can even fit you with modified multifocal contact lenses which is a combination of both multifocal lenses and monovision. Some times you have to get very creative!
