Do you know 40 somethings who complain about the fine print? Are they having trouble reading between the lines? Too stubborn to seek help for their vision problems? Don't want to succumb to the half-size bifocals?
The fact of the matter is that millions of Baby Boomers are coming of age, and are therefore seeing (or not seeing) the signs of failing vision. As people age, their eyes lose the ability to change focus from distant objects to near ones. Thus, a large percentage of this population approaching or at age 45 are suffering from presbyopia or "aging eye." Fortunately, advances in contact lenses and lens care technology over the last 10 years have revolutionized the way 40 Somethings are dealing with presbyopia and vision correction.
Multifocal contact lenses now come in Dailies i.e Dailies Aquacomfort plus multifocal or 1 Day acuvue Multifocal, in monthly formats i.e Biofinity Multifocal or even in multifocal lenses you can wear overnight for example Purevision Multifocal.
Whether the problem is reading a newspaper or seeing a street sign, many 40 Somethings are finding that contact lenses offer a more convenient and aesthetically pleasing means of vision correction. Furthermore, contact lenses don't get in the way of an active lifestyle. They allow wearers to maintain complete peripheral vision, they don't steam up, and best of all, they don't change your natural appearance unless you want them to.
If a 40 Somethings suffers from nearsightedness, farsightedness, an astigmatism, or they need bifocal correction, varifocal contact lenses have a comfortable feel and natural look that offers a convenient way to deal with vision correction.
Following are some important facts on the different methods of correcting presbyopia using contact lenses:
- Multifocal contact lenses. "Multifocal" is a catch-all term used to describe contact lenses that have different powers of vision in the same lens. Some examples of multifocals include concentric lenses, aspheric lenses and translating lenses. All of these lens types are designed to give you a clear field of vision in near, far and middle distances by shifting your gaze. Multifocal Contact lenses are either weighted to stay in place, or are thinned out at the top and bottom to stay in the correct orientation in relation to your lids. Multifocal contact lenses work on a 'simultaneous vision principle' in that both distance and near vision are in focus at the same time, and you learn to ignore one and see the other, depending on the task in hand. Multifocal lenses can come with a centre near or a centre distance design, and your optometrist will judge which is best for you. Many people are able to adjust to a multifocal lens within days. Others will not be able to tolerate them and may need to try alternative methods.
Multifocal contact lenses require careful fitting by an optometrist in order to get the correct powers to enable you to see comfortably at all distances. Sometimes the optometrist can make the smallest change to a power, either distance or near in the contact lens, and this can have a large impact on the quality of the users vision. Aftercare appointments to make these adjustments are very important to the overall chance of success.
Typically, it takes 2-3 weeks to fully adapt to Multifocal Contact Lenses
- Inducing monovision with contact lenses. Another treatment method involves training one eye to be nearsighted and the other eye to remain farsighted. This is accomplished by over-correcting vision in one eye with a contact lens. While this may sound nauseating, the brain quickly learns which eye is for which task. Adaptation is usually quick and hassle-free. If you're still having problems adjusting after a week or so, check in with your optometrist. Some people will not adapt to monovision. If you already have good vision and don't wear correction at all when presbyopia develops, inducing monovision with a contact lens in one eye may be the simplest way to give you back your close vision.
- Modified Monovision. Here you wear a multifocal lens, usually in your non dominant eye, which is adjusted by the optometrist to give better near vision, with some compromise in the distance, and in the other eye a standard distance lens. If you don't read a lot, or do a lot of close work, this can be an ideal solution.
- Contact lenses plus a pair of reading glasses. If you spend hours a day reading, doing needlepoint, writing by hand or doing other close work, it may make sense to wear close-vision glasses over the top of your distance contact lenses when you are doing extended near tasks.
How Will I Know What Correction Method Is Best for Me?
Choosing which method is best for you depends a lot on your particular case and your personal preferences. Some people cannot learn to tolerate eyeglasses on their face, especially if they've never worn glasses before. Others cannot get used to contact lenses or are not keen on putting their fingers in their eyes. Your optometrist can work with you to discover what methods you're comfortable trying. It's not at all uncommon to need to try a few different solutions before finding the one that's best for you and your circumstances.
As you can see, there are many different options available for treating this perfectly normal consequence of aging. With so many options available, there's no need to go through life holding reading materials at arm's length or giving up your favorite hobbies. Speak to your optometrist about the options he or she would recommend. There's no reason to suffer with poor vision when correction is often just an office visit away.
