Contact Lenses, or just contacts, are thin, near-absorbent lenses placed directly on your eye’s surface. Contact lenses are versatile ocular prosthetics that are used by more than 150 million individuals worldwide, and yet they are frequently worn for cosmetic or corrective reasons alone. For those who suffer from certain vision problems that otherwise wouldn’t be addressed by glasses, contact lenses offer a great alternative to improving your vision. Although some people choose to wear their contact lens throughout their lifetime, others only need their contact lenses to be replaced once they’ve determined that their vision has improved.
bifocals and trifocals
Contacts come in a wide variety of styles, each tailored to fit each individual’s particular needs. There is both soft and firm pressure fitting soft contacts, as well as daily disposable contact lenses. If you’ve always worn glasses, then you may be accustomed to the large, round contact lenses that are prescribed by your optometrist. Contact lenses are also available in the form of bifocals and trifocals. When it comes to choosing which kind is best for you, here are some things to keep in mind:
One major factor considered in the choice of contact lenses is the person’s refractive errors
Corrected, refractive errors can be categorized into two: nearsightedness and farsightedness. To determine which eye correction needs to be addressed, your optometrist will evaluate to determine if your refractive errors are suitable for wearing contact lenses. Typically, you’ll be given a prescription for the level of correction that is most appropriate for you based upon your specific refractive error. Your doctor can prescribe either soft or firm contact lenses. The choice is entirely yours.
LASIK eye surgeries have managed to alter the shape of their eyes
Another consideration for those who are considering wearing contact lenses is whether the vision correction is secondary. Through surgery, wearers of LASIK eye surgeries have managed to alter the shape of their eyes from those with nearsightedness to those with farsightedness. For these individuals, the alteration is usually of a more superficial nature. This means that it may not be possible for wearers of corrective surgeries such as LASIK to ever change their eye color, for example. Therefore, contact lenses may not always be the best option for these wearers.
Whenever you’re wearing your contacts, ensure that your eyes are clear all the time
As an additional safety measure, you must inform your optometrist of any prior eye problems you may have, both acute and chronic, including any medications you may be currently taking. In addition, your optometrist should inform you if you are taking any other medications, including vitamins, that can alter your eyesight. Optometrists also advise patients to refrain from driving or operating machinery while wearing contact lenses. Whenever you’re wearing your contacts, ensure that your eyes are clear all the time.
If you decide to wear lenses instead of glasses, it’s important to follow some basic eye care tips
Always use clean, sterilized solutions when handling your contacts. Even if you use brand name contacts, be sure to clean them in between each contact. You can also help to prevent dry eyes by frequently wiping your contacts with a clean cloth before they are applied to your eyes, and by protecting your glasses or contact lens from scratches, either gently with an appropriate product, or by not rubbing them against your face.
