Disposable 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.
