Eye Contact Lenses

Things You Should Know About Eye Contact Lenses

Eye contact lenses are often touted as being far better than glasses and in many ways. However, it is a good idea, to know enough about contact lenses before buying them to make a best choice.

Types of Eye Contacts Lenses

Mainly there are three types of eye contact lenses, soft, hard, 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 eye 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 eye contact lenses are becoming very popular now days, since we can just use them and dump them. These are the cheapest types of lenses, but they are usually not specifically made for our eyes, which can cause issues.

In addition to disposable eye contacts lenses, we can get one week or even one month contacts which are designed to stay in our 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, saline solutions, etc. which can get confusing and messy, not to mention they are rather time consuming.

Different eye conditions require different types of contact prescriptions which may only be available in one type of contact. Also, our daily activities may dictate the need for a specific type of eye cobtact lenses.

Wear and Care of Contact Lenses

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

There are other issues with wearing eye contact lenses. For example, we should not wear them in the pool or while showering, since they could be flushed out of our 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 our contacts while we shower or swim.

Looking after our contacts can be simple or complicated, depending on what type we use. Disposable eye contact lenses do not require any cleaning, we simply toss them when we are finished using them. Other, reusable contacts will need more care. We 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 our eyes are sensitive, we may have to experiment with various brands of cleaning solution to find one that does not irritate our eyes.

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

Contact Lenses And Astygmatism

A debate continues as to whether astygmatism and contact lenses are compatible bed fellows. For many years, it was unclear as to whether contact lenses of any sort could assist an astigmatism sufferer.

Astigmatism is a misshaping of the the cornea. A normal cornea is round, but in an astigmatism sufferer, the shape is more like an American football, or rugby ball. An astigmatic eye sees light focusing on two points in the back of your eye, rather than on just one in a normal eye. This is because an astigmatic cornea has a steeper and flatter curve due to the shape of the cornea. This is called corneal astigmatism.

Sometimes, astigmatism is the result of an irregularly shaped lens, which is located behind the cornea. This is called lenticular astigmatism.

Either kind of astigmatism can usually be corrected with spectacles or contact lenses. In some case, refractive surgery can also help astigmatism sufferers.

Astigmatic Symptoms
==================

If you have only a small amount of astigmatism, you may not notice it or have just slightly blurred vision. You may have had the problem for many years but never noticed, because small changes over many years may not have indicated a problem to you. However, uncorrected astigmatism may also give you headaches or a pain behind the eyes, which you might think of as eyestrain. Or, you may notice distorted or blurred vision at all distances.

Astigmatism can also affect children. Astigmatism can affect their ability to see properly in lessons, so it's vitally important that children have their eyes examined at regular intervals in order to detect any astigmatism early on. I personally started complaining to my parents when I was about 8 that I could not see the blackboard at school properly. I was taken to doctor, who advised my parents that I was just trying to get out of school. My continued complaining however, eventually led my parents to find the only optician in town (this was some years ago) who confirmed short sightedness and astigmatism.

I would certainly hope that my children get a more sympathetic ear from the medical profession then I did all those years ago.

Treating Astigmatism
==================

Unless it is extreme, astigmatism can be treated with glasses or contact lenses.

Many people with astigmatism believe that they can't wear contact lenses at all, which is something that was alluded to at the start of this article, or that only hard (also called gas permeable - GP) contact lenses can correct astigmatism.

For many years, this was the case, but now there are soft contact lenses available, that correct astigmatism. These are called toric contact lenses.

Toric lenses have a special correction built into them and may also contain a prescription for nearsightedness or farsightedness if you need it.

While soft toric lenses work well for many people, if you have severe astigmatism, you might find that GP contact lenses or spectacles help you more. Your optician will be able to advise you. The article was written by Charlie Cory, who is the owner of FX Eyes, a website dedicated to providing advice about buying special effects contact lenses online.

What to Do If Your Contact Lenses Don't Feel Comfortable?

Many people give up wearing contact lenses because they can never get used to them. The lenses just don't feel comfortable. If this is your case don't give up just yet; there are several things you can do to make your lenses more comfortable.

If you contact lenses feel dry

How many glasses of water do you have every day? Not soda, coffee or tea, but water? It is possible that your dry eyes are a result of general dehydration. Try to drink more water. We all know that water is on the "good for you" list, but we often forget about it during our busy days.

If you work at the computer all day, your eyes are definitely drier than they would be, otherwise. The reason is that while peering at the screen people blink much less than usual. You can't control your blinking, but you can try closing your eyes for a few seconds, at regular intervals.

Do you drink a lot of tea, coffee or soda that contains caffeine? They all are dehydrators so, if you like coffee, you need to drink even more water than usual.

Also you can ask your doctor if silicon-hydrogel contact lenses would suit you. New generation silicon-hydrogel contacts don't block oxygen flow to your eyes as much as ordinary lenses. Quite often contact lens wearers report that silicon-hydrogel contacts, like Acuvue Advance, Focus Night and Day or O2 Optix, solved their dry-eyes problem. See reviews of most comfortable contact lenses.

Eye drops can also be a solution, but only if your eyes occasionally feel dry. You shouldn't use eye drops all the time

You constantly feel the lens in your eye

High quality contact lenses that are properly fitted to your eyes should feel like you have nothing in your eye at all. See if these recommendations can help..

Are you often exposed to cigarette smoke or dirty environments? Tiny particles that get under your lens might be the cause of your discomfort, try to avoid smoke and dusty rooms if possible.

Do you follow your doctor's instructions about cleaning your contacts every day and replacing them on schedule? It is possible that proteins from your eyes have built up on your lenses. It is very important to care for your lenses properly

You can also switch to daily disposable contacts. They don't require any care at all, and every day you start with fresh lenses that have no build-ups from the previous day. Daily disposable lenses are definitely a solution for people who have to spend a lot of time in dusty environments.

The reason for lens awareness might be that the lenses simply don't fit you. Contact lenses have many parameters and have to be properly fitted by an eye doctor. You can't just select the brand you like and order it online.

Your eyes feel swollen, red and irritated

This is a sign of a serious problem and, whatever the cause might be, the only sensible thing to do is to take your lenses off immediately and don't wear them until you can see a doctor. Most likely the lenses are not the source of your problem, but your eyes will heal better if there is nothing in them.

Black Contact Lenses - Can Special Effect Contact Lenses Enhance Your Eye Style?

One of several types of theatrical or special effects contact lenses available, black contact lenses are very popular.

The lenses are a great addition to any Halloween costume, and give eyes an appearance that is sure to attract attention. For the ultimate fashion accessory, black contact lenses offer both style and function.

Black contact lenses come in more than one style. The most commonly seen style makes the iris, or colored part of the eye, completely disappear. Some are opaque, so that even the pupil does not show through, while others only cover the iris. There are also black lenses, called sclera lenses, that are larger in size and make the white of the eye look black.

While the regular black lenses fit in the eye like any other contact lens, the sclera lenses are larger and tend to be more uncomfortable. In addition to that, the black lenses can be corrective or cosmetic.

Costume contact lenses are generally available for purchase wherever colored contact lenses are sold. As with any contact lens, the size and shape must be determined through an eye exam. If the lenses are meant to also correct vision, then the prescription strength must also be determined through an eye exam.

Once you know your prescription measurements, you can purchase theatrical contact lenses through an optometrist/optician or by ordering from contact lens suppliers online. Because black contact lenses are not a commonly purchased item, optometrists/opticians may need to order them, so you should allow time for them to be ordered and received if you choose to buy through an office. Ordering online can usually ensure that you receive your special effect contact lenses more quickly.

Ordering lenses online is actually a simple process. Once you find a retailer who carries the costume contact lenses that you want, you add the item to your cart like you would with any other online retailer. You will be asked to supply your prescription information so the retailer can send you the correct size and shape for your eye, and you will be asked to enter the name of the physician who performed your eye exam.

Black contact lenses vary from simply making the colored part of the eye disappear to making your eyes appear completely alien. Regardless of the type you choose, the lenses are the perfect accessory for Halloween costumes, parties and clubs, and just making people look twice.
