Bifocal Lenses


At Doctor Dorothy Park & Associates, your eye doctor in Columbia, SC, you’ll find easy answers to one of life’s more common annoyances.

Do you wear eyeglasses? That or contact lenses are the usual treatment for what we call nearsightedness, or difficulty in seeing objects that are farther away from us. You might have first received a prescription for eyeglasses to treat nearsightedness as early as grade school, though the impairment could occur at any age.

But just to prove that life isn’t fair, once we 40 or so, many of us begin to also experience the opposite vision condition, one with the somewhat scary name of presbyopia. It’s more simply known as farsightedness. This means that we now also have difficulty clearly seeing objects that are close to us, such as when we’re reading.

The solution? That’s easy. Simply wear two kinds of lenses and alternate frames. Wear one pair of eyeglasses when you need to see objects in the distance, such as when driving. And then switch to eyeglasses with lenses to offset your presbyopia, such as when you’re trying to read a menu or a newspaper.

What a hassle, huh? Fortunately, there’s a much easier answer: bifocal lenses.

Two Vision Fields in One

Bifocals were ingeniously invented by Benjamin Franklin way back in the 18th century. All he did was put two lenses together in one pair of eyeglasses with a horizontal split-screen. The lens, or “power zone” on the bottom makes it easier to see objects close at hand while the upper lens is for viewing things farther away.

While the technology has changed since then, the concept is pretty similar to that original invention. All your eye has to do is shift from one lens to the other as your vision needs change. There’s no swapping out eyeglasses or finding that you left your reading glasses home when you need to see a restaurant menu. All your vision correction needs are in a single pair of eyeglass frames. What could be easier?
