Daily Wear Contact Lenses
Daily wear contact lenses are the most popular type of contact lens on the market today because of the ease in which they fit the idea for comfort and vision correction. These lenses are very soft, almost gel-like and the "break in" time for one's eyes to get used to them is shortened considerably from the gas permeable type of lens. These vision correctors are meant to be worn all day long for about a week and then replaced with a new set. They are taken out at night for sleep and must be cleansed each day because of the proteins and micro-organisms that form on them while in the eye. There are also very soft lenses that are replaced each day, and can be even softer than the daily wear contact lenses version. Discarded each night, these disposable types of vision correctors are even more expensive than the daily wear type of lens.
There are, of course some real advantages to wearing daily wear contact lenses. They are a favorite of many athletes who must wear vision correction devices on the field or on the court but cannot be bothered with glasses that can be broken or falling off. They are also favored by many who like the aesthetics of contacts over glasses. They may actually be required for some jobs that cannot allow glasses on the job such as actors who may not have gotten a particular job had they worn glasses. Over one hundred and thirty five million people worldwide wear vision correction lens in either one or both eyes.
Getting fitted for contact lenses is really no different than getting glasses, but because the fit is so important, one might want to consider going to an ophthalmologist rather than an optometrist for the best fitting. An ophthalmologist has more training on the physiology of the eye and is an MD. The exam to get daily wear contact lenses or any other type of corrective vision device is very important and will need very precise measurements of the eye to fit the contact lens correctly. The Christian life is full of paradoxes such as giving in order to gain, mourning over sin in order to be happy and being last in order to be first. Included among these paradoxes is one about sight: "For we walk by faith and not by sight." (II Corinthians 5:7) This means that no matter what happens to us, we know by faith that God is with us.
Here is a real good question before a person can ever really get a corrective lens that fits right on the eye. Can you take your finger and touch your eyeball directly? If one is squeamish about this, better think twice about ever getting daily wear contact lenses or any other type of lens that goes directly on the eye. And what happens if the lens slides off the center of the eye and disappears above the eyeball? You'll have to go after it, but don't worry, the lens will be stopped by the eyelid; the lens won't disappear behind the eye! These are things to consider before investing in an expensive pair of daily wear contact lenses. Once a person knows that he can handle the everyday issues that certainly occur with these types of corrective visions devices, a person will have to decide what kind to get.
If you have astigmatism, you will probably be directed to oxygen permeable lenses which are a little harder than soft lenses that are more gel-like. Contacts are broken down into daily wear and extended wear types, with the daily wear contact lenses having to be taken out each night while the extended version can be worn up to seven days without having to be taken out. Whatever type you choose, or your doctor chooses for you, contacts have to be cleaned regularly or they can get to be very uncomfortable. The daily disposable kind can be thrown away every day, the disposable every two weeks, and continuous wear can be worn for thirty days before a new pair is needed. The oxygen permeable lenses are not disposed of on such a rigid schedule.
The eye care professional that a person chooses will know what kind of contacts are right for your eyes. With some eyes being quite dry, certain lenses will not be as beneficial. For the truly fashion conscious, contacts can allow a person to choose the color their eyes will be, with a number of fashion hues from which to choose. Once a person has gotten the exact eye prescription and fit for contacts, the choice can be made to purchase them from the doctor who examined you or buy them from some supplier on line. If the buyer is a first time daily wear contact lenses user, the strong advice would be to get the contacts from the doctor who prescribed them. That way any errors in measurement will be taken care of by him or her. Veterans to wearing them will probably look for the best supplier's price somewhere on the Internet.
There really isn't a right age for beginning to wear contacts, and each doctor may feel differently about when it is age appropriate for them. If one's child is very careful and fairly disciplined, perhaps a youngster can handle them without a real problem. But if your child is a terror and everything falls apart as he or she walks by, big thick athletic glasses might be a better choice until he is a little more mature. Read up on contacts as much as possible before going into your eye doctor. Being well informed can go a long ways towards having a life time love affair with these great alternatives to those thick athletic glasses!
Disposable Contact LensesDisposable contact lenses are ideal for a person who has an active lifestyle or chooses not to wear them every day. They are available through different companies and are even made for people who have astigmatism. Daily contact lenses help to lower the risk of eye infection or irritation. Compared to other lenses such as the typical ones that can be worn for a month at a time, daily and disposable are a little more expensive but the convenience makes them worth the extra cost. For the most part, ordering these through an optician can mean higher prices compared to ordering through companies on the Internet. To order a person must have a current prescription that has not expired. Most companies require a copy of the actual prescription but will contact the optician for the information if the consumer has misplaced their own. Brands vary in the way they are made and the way they feel so the patient needs to know the brand that has been used.
Some of the different types of contacts include soft, gas permeable, extended wear, disposable, special, and decorative. The two main ones are soft and gas permeable. Soft are the most popular and come in extended wear, disposable, and decorative. Soft comes in disposable contact lenses and are much more comfortable than the rigid gas permeable ones. Soft types are made of flexible plastics and some include silicone-hydrogels. Silicone-hydrogels helps to give the eye more oxygen. Some people prefer gas permeable because they are resistant to buildup and provide clearer vision. Gas permeable is a little harder to get use to because they can be felt more in the eye than soft contacts.
Extended wear contacts are made to keep in continuously and even sleep in and some are made to keep in as long as 30 days at a time. However, the eyes do need a rest periodically so most opticians do not recommend keeping contacts in that long. Daily contact lenses are made to be used during a one day period and then discarded. To avoid damage to the eye a person should consult with an optician on the best choice that goes with his or her lifestyle. If a person has a bad habit of keeping lenses in too long then disposable or dailies will be a better choice. The eyes can become scarred and infection is more likely when contacts are kept in too long. Scarring will affect vision and could cause other types of problems. Ask the Lord for wisdom and listen to the eye doctor when wearing lenses. "For the LORD giveth wisdom: out of His mouth cometh knowledge and understanding." (Proverbs 2:6)
Some symptoms of eye infection include lesions, inflammation, blurring, discharge, swelling, pain, light sensitivity, and vision loss. If any of these symptoms are experienced a person should discontinue wearing lenses and see an eye doctor as soon as possible. One way to avoid an eye infection is to switch to disposable contact lenses and change them every day. Other ways to avoid infection is to use a solution that cleans and disinfects. Use fresh solution every day and clean the case every day. Gas permeable should be cleaned daily and put in a disinfecting solution at night. Care should be taken to not scratch the lenses when cleaning. In addition to a no rub solution and disinfectant an optician may suggest using an enzymatic cleaner to help remove protein deposits. Gas permeable should not be rinsed with tap water after cleaning because regular tap water can encourage the growth of bacteria.
Special choices are ones that come in bifocals, different colors, ortho-k, special effects, monovision, and torics for astigmatism. Ortho-k corrects vision by reshaping the cornea while worn and even after removing the correction will stay for several hours or longer. Monovision is when one eye is fitted for distance and the other is fitted for up close work and reading. Torics are made specifically for individuals who have astigmatism. Most of these come in daily contact lenses, two week disposable, extended wear, and monthly.
An examination to be fitted for contact lenses usually cost a lot more than an exam for eyeglasses. An ophthalmologist will fit the eyes with sample lenses for the patient to try. Normally several visits have to be made to the eye doctor to get the right fit and prescription. Once the right prescription is determined an order can be placed through the optician. There are some prescriptions that the optician may keep in stock. Disposable contact lenses are often kept in stock because they are highly recommended and are usually the most popular. With disposable there are no solutions needed, little risk for infection, no protein buildup, and more convenient to use. People who do a lot of traveling will normally choose these because they do not have to worry with cleaning solutions nor take the time to care for them.
People who like to sleep in their contacts will often choose extended wear to keep them in continuously. Some brands allow for continuous use up to seven days and some allow for continuous use for up to 30 days. Daily contact lenses made for extended wear should be taken out at night. Many eye doctors do not like to prescribe extended wear to keep in overnight because the risk of infection increases with these. For the most part wearing them overnight occasionally should be fine but to wear them every night is not advisable unless contacts are disposable and are changed out frequently.
