Contact Lens Types

Soft contact lenses have been released in many different formats since they were first developed in the 1960s.

Soft contact lenses were originally designed to be worn for 12 to 18 months and removed nightly. These contact lenses are now called ?conventional soft contact lenses?. They are usually prescribed as a specialty lens and are generally used when frequent replacement or disposable contact lenses are not available. They have the disadvantage of being more expensive and tend to accumulate surface deposits. This mode of lens wear requires more diligence with cleaning and care.

Disposable contact lenses were first released commercially in the 1980s. The first disposable lens was the Johnson and Johnson Acuvue contact lens, which was a 2 week disposable contact lens. It was a soft hydrogel lens and was primarily worn on a daily basis. The original Acuvue contact lens has only recently been discontinued. It was designed to be replaced after 2 weeks of daily wear.

Soft disposable silicon hydrogel contact lenses were first available in the 1990s. The first silicon hydrogel lenses offered were the B&L PureVision and Ciba Focus night & Day lens. Both these lenses are approved for one month extended wear. Silicon hydrogel contact lenses have the advantage of greater oxygen permeability than the original hydrogel contact lenses. Approximately 98% of patients are able to wear this type of contact lens. There is however, a slightly increased chance of developing microbial keratitis or corneal ulcer with this mode of wear. Some studies place the risk at one in five hundred per wearing year.

The next generation of silicon hydrogel soft disposable contact lenses saw the release of Ciba Optix O2 and Johnson and Johnson Acuvue Oasys. These lenses have an improved surface treatment, which leads to improved hydration and increased comfort.

More recently daily disposable soft hydrogel contact lenses have become increasingly popular. These lenses, such as J&J 1-day Acuvue Moist and CibaVision Focus Dailies have the advantage of being more hydrophilic and retaining moisture during the day.

Focus Dailies contact lenses contain AquaRelease to improve hydration and are replaced daily, leading to increased comfort from a cleaner lens. Daily replacement lenses also have the advantage of lower complication rates due to the lenses developing less surface deposits and lower infection rates. Obviously a contact lens case is superfluous with this mode of lens wear. Contact lens cases have been found to be a major source of microbes that can cause eye infections.

Contact lenses are now also available to buy online, meaning a faster, cheaper and more convenient alternative in purchasing your lenses. Contact lens wearers should still maintain a responsible attitude to lens wear, and have their eyes checked regularly by their eyecare practitioner. They should also check their own eyes daily for eye infections, by following the ?Look OK, See OK, Feel OK? regime. Each morning after inserting the lenses they should check each eye look white, then check the vision in each eye separately, and then blink once or twice and ensure there is no discomfort. If there is any change, they should remove the lenses immediately and consult their eye care practitioner.

What You Need To Know About Contact Lenses

Contact lenses are often touted as being far better than glasses and in many ways they are. However, it?s a good idea, like anything, to know enough about contact lenses before buying them to make an educated decision.

Types of Contacts

There are three main types of contact lenses, hard, soft and disposable. Hard contact lenses are rigid and can be more irritating to the eye, but they do last a lot longer, up to three years. Soft contact lenses are easier on the eye and can be worn for longer periods of time. They are usually replaced after a year or so of use. Disposable contact lenses are becoming very popular these days, since you can just use them and dump them. These are the cheapest types of lenses, but they are usually not specifically made for your eyes, which can cause issues.

In addition to disposable contacts, you can get 1 week or even 1 month contacts which are designed to stay in your eye for longer periods of time, but need to be tossed afterwards. Many people prefer disposable contact lenses because they eliminate the need for cleaning and saline solutions, etc. which can get confusing and messy, not to mention they are rather time consuming.

Your eye care professional is the best person to help you choose the right type of contact lenses for you. Different eye conditions require different types of contact prescriptions which may only be available in one type of contact. Also, your daily activities may dictate the need for a specific type of contact lens.

Wear and Care of Contact Lenses

Many people find that the first few times putting their new contact lenses in is a bit scary. You need to overcome the natural instinct to keep foreign objects out of your eye in order to insert them and this is more difficult for some people than for others. Usually this is just something you have to do a few times in order to get over it.

There are other issues with wearing contact lenses. For example, you shouldn?t wear them in the pool or while showering, since they could be flushed out of your eyes or get water trapped behind them. Water that has chlorine in it is particularly irritating, but even regular tap water can contain bacteria that can be caught behind the contact lens and cause an infection. The easiest way to prevent problems like this is to simply remove your contacts while you shower or swim.

Looking after your contacts can be simple or complicated, depending on what type you use. Disposable contact lenses don?t require any cleaning, you simply toss them when you are finished using them. Other, reusable contacts will need more care. You will have to soak them in a cleaning solution and rinse with saline. In some cases, more drastic measures need to be taken to remove protein or calcium deposits, including special tablets that dissolve in the regular cleaning solution. If your eyes are sensitive, you may have to experiment with various brands of cleaning solution to find one that doesn?t irritate your eyes.

Contact lenses offer a freedom from glasses, but they aren?t completely hassle free. Knowing what to expect is the best way to make a good decision as to whether contact lenses are for you or not. Talk to your eye care professional as well to get more information, since he or she will know your specific case and is in a good position to recommend the type of contacts necessary.

Contact Lenses And Water Don't Mix

A very common question that new contact lens users ask is whether or not they can go swimming with their contacts in. Others wonder if it's ok to shower or bathe with their contacts, or even splash water on their face. There are a lot of water-based activities in our daily lives and sometimes contacts don't fit into those activities too well.

Swimming with Contacts

It's never a good idea to swim with your contact lenses in. In fact, it could be very bad for your eyes. In a pool, the chemicals needed to maintain the pH and the chlorine can irritate your eyes under normal circumstances, but with contacts, they will be trapped right up against your eye, even after you get out of the pool and the pool water can actually cause infections as bacteria are introduced to the eye.

In addition to the above issues, contacts absorb water. If they absorb pool water, with all the chemicals, it can be common for the contact lenses to actually stick to the eye itself. While this is usually not serious, it can definitely be uncomfortable. To correct the problem, leave the contacts in and don't try to remove them until your natural tears have replaced the pool water in the contact lenses.

Even if you go swimming in a lake, it's not a good idea to use your contacts as they can actually be floated out of your eye by large quantities of water. However, if you need your contacts while swimming, a very tightly fitted pair of swim goggles can help ensure that they don't get lost.

Showering and Bathing with Contacts

Showering offers the same hazards as mentioned above with swimming. The quantity of water can wash the contact lenses right out of your eyes and may cause problems if your water is chlorinated. While the exposure to chemicals is probably not long enough to cause issues, there is a chance that chlorine will be trapped behind the contact, causing irritation and discomfort.

Some people do manage to shower with their contacts in, by simply not looking up into the water or by closing their eyes during the shower. While possible, it's not advisable. There is a pretty high risk that you'll lose your contacts and they can easily be washed down the drain, making it impossible to recover them. It's a better idea to simply wait until after your morning shower to put your contacts in.

Taking a bath shouldn't be a problem, as long as you don't go under the water. It's possible to wash up without risking the loss of your lenses and this shouldn't be an issue. Most people don't submerge themselves in the bathtub anyway.

Face Washing with Contacts

In general, you should be able to wash your face with your contacts in, as long as you aren't splashing water into your eyes. Regular face washing is just fine. Most people close their eyes anyway while washing their face, which ensures that your contact lenses will remain firmly in place.

Contacts and water don't mix, particularly water that has been chlorinated. There are situations, like a bath or washing your face, when you don't necessarily have to remove the contact lenses, but to be sure you don't end up with overly irritated eyes and lost contacts, it's best to just avoid using contacts when you are swimming or showering. This will keep them safe, particularly if you aren't using disposable ones and have paid a chunk of change for your contacts!

Contact Lenses - Tips And Tricks For First Time Users

It's quite common for people to avoid getting contact glasses or lenses because they are unsure of how to put them in... or even that they will be able to deal with having something in their eyes every day. However, contacts are really quite easy to use, once you get the hang of it. The first couple of times, you may be hesitant, but this article will show you how to put your new contact lenses in and how to ensure that they don't bother you.

To make sure that your contact glasses don't have calcium build up that could irritate your eyes, you'll want to soak them in lens cleaning solution for at least 4-6 hours. This will loosen up anything that has built up during the time they have been in the package. After the soak time, rinse your contacts thoroughly with saline solution (NOT tap water) and check them for any scratches or tears. Then you're ready to put them in.

You should wash your hands with soap and water before handling your contact glasses. This just ensures that no dirt or grime will get trapped under the lens where it can irritate your eye. Also, dry your hands carefully, since a wet fingertip will tend to stick to the contact, making it harder to insert.

Once you have prepared everything and your hands and contact glasses are nice and clean, you are ready to get started. Take the first contact lens and place it on your fingertip. It should look like a little bowl sitting there, with the top edges horizontal. Soft contacts can get turned inside out by accident sometimes and if this happens, you'll notice that the edges flare out. Just turn it right side out and it will be fine.

The easiest way to put your contact glasses in is to place the contact lens on the index finger of the hand closest to your eye, left hand for left side, etc. Use the middle finger of that same hand to pull the lower eyelid down and the opposite hand to lift the upper lid. Basically, you want your eye open as much as possible, you should be able to see the entire colored part of your eye.

Now, place the contact gently in the eye, making sure that it doesn't stick to your finger and let go of your eyelids. Blink a few times and the contact will automatically center itself. You should be fairly comfortable at this point. But, to make sure that you don't have any problems, you'll want to make sure that you don't wear your new contacts for very long the first few times, since they can be drying to the eyes.

Following the recommended time schedule for wearing your contact glasses is definitely a good idea, but you might want to use some lubricating eye drops (ask your eye doctor for recommendations) to help ease any discomfort. It's normal to have slightly irritated eyes the first few times that you wear contacts. You might find that your eyes tear up and get a bit red, but that's normal. However, pain is not, so if you have any pain, just take them out.

Trying out contact lenses for the first time can be a bit nerve-wracking, but it will get easier. Within a week, you'll be a complete expert at putting your contacts in and taking them out!
