If you have decided to use contact lenses, or just getting yourself a new pair, you might not be aware that there are so many contact lens options for you. But just as you are getting any kind of medical device, keep in mind that choosing the right contact lenses for you should be performed with caution and care.
First, you need to pick from the two general types of contact lenses: soft or hard. Majority choose soft lenses, roughly about 90%. Hard lenses are best for those who are suffering from astigmatism as well as those who have a tendency to form protein deposits on contact lens. When you have chosen between hard and soft, proceed to the many contact lens categories available today.
- Daily wear contact lenses
These are usually the cheapest option. They are worn during the day and are taken out then disinfected each night. They are replaced every 2 weeks up to every 3 months, according to the brand and type.
- Extended wear contact lenses
These can be worn even when sleeping, although they will have to be taken out at least once in a week for disinfection and cleaning. Many health care professionals, however, do not recommend that they be worn overnight as they make the eyes more susceptible to infection.
- Disposable contact lenses
These lenses can be discarded each day after use, sparing you from any maintenance. They might cost more but they offer convenience. They are best for those who have allergies or have conditions of exaggerated protein formation in their eyes.
- Toric contact lenses
These are used for correcting astigmatism, an eye problem where there is blurred vision due to irregularly shaped corneas or lenses of the eye. This lens is mostly a little more costly than the other contact lens types.
- Colored contact lenses
These contact lenses are colored so that they can change or enhance your eye color. They are mostly worn for cosmetic purposes although there are those that are designed for vision correction.
- Multifocal contact lenses
This is the type that is used by people who have a hard time focusing on close objects. One common technique is called monovision where the dominant eye wears contact lens for distance while the non-dominant eye wears one for near vision.
When you are buying contact lenses, remember these safety tips.
- Make sure that the package of the lens us sealed properly before buying it.
- Be cautious when purchasing contacts lens off of the internet. If you must, buy from reputable websites that sell products with brand name.
- Use the most recent prescription from you eye doctor. They are good for a year after the date that they are written.
Although you will not need to correct your vision, it is still important that you consult an eye doctor before buying cosmetic lenses. Also make sure that you get them properly fitted and monitored through follow-up consultations to keep yourself protected from eye infections and any other problems.
