Progressive Contact Lenses: Fight Aging Eyes
If you need bifocals or trifocals and you've never heard of progressive contact lenses, then read on for some information about contact lenses that just might change your life.
It's an unfortunate fact that, with age, our vision quality declines. Nearly almost everyone, eventually, develops presbyopia; a natural condition of the eye inhibits your ability to read things up close. If you've noticed that you have started holding books, magazines, and menus out further from your face, usually at arm's length, they you have likely developed presbyopia.
However, don't panic! This doesn't mean that you are sentenced to a life of bifocal eyeglasses hung around your neck like grandma used to wear. Thanks to advance in technology, there are now a variety of contact lenses that can help nearly every vision correction need; and progressive contact lenses are among the most advanced.
But what, exactly, are progressive contact lenses? Most people know what bifocals are; the old-fashioned “granny” glasses that have a visible dividing line between the top lens, which allows for distance vision, and the lower lens, which helps with reading. In the last decade, bi focal contact lenses became popular; and now, progressive or multifocal contact lenses are changing the way people see.
However, one disadvantage to bi focal contact lenses is what is referred to as “image jump.” This occurs when the eye moves over from one power (near or distance vision) to the other. The dramatic change in powers makes the eye have to refocus quickly, and makes whatever you are looking at appear to jump. This can be annoying and, in some people, can cause dizziness.
Progressive contact lenses contain a variety of vision “power” within one lens. This allows you focus and have clear vision at all distances, from reading up close to far in the distance, and everything in between. Unlike bifocals, the varying powers within a progressive lens are not separated by lines or segmented vision zones, so “image jump” is no longer an issue. Instead, your vision changes smoothly as your eye progresses through the varying powers that are blended together throughout the lens. This is the closet thing to natural vision that is available in the contact lens market today.
However, these specialty lenses are not without their challenges. Not everyone is a candidate for progressive lenses. Some people, since progressives require such a specific fit, are never able to perfect their prescription, or have to change their prescription often. Be sure to consult with your eye care professional to see if you are a candidate for progressive lenses.
Nearly every major contact lens manufacturer offers a progressive lens, so it's worth your time to do some research. Some brands offer progressive daily disposable contact lenses, other offer extended wear. There are both soft or RGP contact lenses (rigid gas permeable) with the progressive option. Determine what you want out of a lens, and then begin researching!
Aging is an unfortunate fact of life; but progressive contact lenses can help lessen the impact by giving you seamless, effortless vision.
