Why Do People Need Bifocal Lenses?

Bifocals help people who are both nearsighted and farsighted see clearly. Bifocal glasses have two different corrective lenses to accommodate this specific vision problem. In some cases, wearing bifocal eyeglasses can also improve vision of those diagnosed with astigmatism or other refractive issues.

Signs You May Need a Bifocal Prescription

One of the main signs your eyes are changing and require bifocal correction is if you notice you see things up close more clearly, when you take off the glasses you are currently wearing. Looking through a pair of prescription bifocal lenses with a special lens insert at the bottom of each lens will allow you to read or see what is written on a computer screen without taking off your old glasses.

If you can read something better while wearing your current glasses and holding the book or pill bottle at arm's length, you probably need bifocal glasses.

Recurring headaches, neck strain and upper shoulder pain may indicate your eyes have changed and need a different prescription. Unconsciously squinting or holding your head a certain way for long periods will eventually cause muscle discomfort in your face, neck and shoulder areas.

Bifocal Glasses Improve Astigmatism and Presbyopian

Even if you are not nearsighted or farsighted, bifocal lenses can reduce blurriness due to astigmatism, a vision disorder caused by having a misshapen eye lens or elongated cornea. Astigmatism also creates issues with glare in sunlight or partial sunlight that may interfere with your ability to see and drive at night.

Bifocals are also prescribed to people with presbyopia, a condition common to those over 40. Aging naturally causes a reduction in the eye's ability to quickly focus on up-close objects. Presbyopia is not a disorder or disease, nor is it similar to farsightedness. Instead, presbyopia is attributed to decreased flexibility in the eye's lens due to aging.
