Avatar, the modern epic directed by James Cameron, is undoubtedly one of the best films of the decade.  This film introduced to mainstream consciousness the Na’vi, which are blue creatures that inhabit this alternate world.  Like the mystical creatures of The Lord of the Rings and the witches and wizards of Harry Potter, the Na’vi of Avatar are fast becoming one of the most popular Halloween costume options for many people.

Aside from stocking up on blue body paint and braided hair, one of the most important elements of the Na’vi costume is the Avatar contact lenses.  There are plenty of colored contact lenses out there that you can use as your Avatar contact lenses—you will just have to make sure that the color is very near the yellowish green tinge characteristic to the creatures of Na’vi.  Just go to your search engine of your choice and type in “Avatar contact lenses.”  You will find a lot of yields out there, but the ones that are more opaque and larger than the common lenses will serve your purpose well.

Avatar contact lenses do not need to be expensive, especially if you are just going to use them for one time.  However, you will need to make sure that your Avatar contact lenses are of good quality.  Contact lenses that are sloppily designed, manufactured, and painted can hurt your eyes and even permanently damage your cornea.  Once your cornea has sustained even the slightest of scratches, your eyesight might suffer permanently.  Of course, you do not want to compromise your eyesight for cheap Avatar contact lenses, so make sure that you choose a good quality pair.

Make sure that you will not be wearing your Avatar contact lenses for more than six hours to ensure that oxygen will flow to the surface of your eyes.

Contact lenses are a great way to change your looks—especially during Halloween, when people are putting together their eerily cool ghoul costumes.  The eccentric musician Marilyn Manson has also been seen wearing white zombie contact lenses, which added to the popularity of these special effect contact lenses.  There is something very inhuman about white zombie contact lenses, mainly because the colors naturally occurring in human eyes are limited to brown, green, blue, and gray.  Most people have this idea that dead people’s pupils are colorless to milky white, and this is also the same for people with physical abnormalities.

When dressing up as ghouls and other scary inhuman beings, white zombie contact lenses are a must.  They are widely available from different contact lens manufacturers, and they are often sold out near the Halloween season, so if you think your costume is going to need white zombie contact lenses, get yours early.

Many white zombie contact lenses feature a transparent hole in the middle, to allow the natural color of your irises to peek through.  The contact lenses will cover the rest of the eyes, giving you the otherworldly look of having incredibly small or colorless pupils.  However, people with darker eyes often have problems with white zombie contact lenses because the actual color of their eyes still show through.  Many good quality white zombie contact lenses offer more color coverage than their cheaper counterparts.

There are also other kinds of white zombie contact lenses, including ones that glow in the dark and those that cover the entire eye.  Glow in the dark contact lenses can be a lot of fun to wear, especially if you are going to a darker place.  Always remember to consult with an eye doctor first before wearing any type of contact lenses to avoid eye infections and complications.

We are quite sure that you have been asking the same question: just what, exactly, are contact lenses made of?  These tiny pieces of what seems to be clear and elastic material have helped millions of people break free from the limitations their eyeglasses imposed on them—allowing these visually-impaired people to see things in a whole new light, literally and figuratively.

Contact lenses are often made from a special transparent polymer, which is cut and shaped by computers.  With the production of contact lenses, the slightest miscalculation will spell ruin for the products.  Precision is highly valued in manufacturing these medical devices, and that is why computers are built and programmed to deliver the same perfect results every time.  Poorly manufactured contact lenses will not only cause blurry vision and discomfort to the user, but it can also pose serious danger to the eyes of the user.

The special polymer used to manufacture contact lenses is very much permeable to moisture—which is an important and unique feature of this material.  The material will need to soak fluids to remain soft and comfortable for actual use.  The solutions and fluids used in the care of contact lenses are also specially formulated to trick the user’s eye into thinking that the polymer “button” on the surface of the eye is not a harmful foreign object.  When confronted with foreign objects, our eyes’ natural instinct is to tear up and expel the intruder—but contact lenses are designed just so our eyes will think they are just tears.

There are also plenty of modern materials used in the production of contact lenses, all of them designed to heighten the user’s comfort in using them on a regular basis.  Many materials now offer improved moisture retention and oxygen permeation for maximum comfort.

For people who have been wearing glasses for years, switching to contact lenses and wearing them regularly might sound a little scary.  Glasses can be very comfortable to wear, but they severely limit the activities you can do.  But even with the advantages of contact lenses, many people are still wary of them.

They have plenty of reason to be wary of wearing contact lenses.  The major concern with wearing contact lenses is keeping everything very clean, because the eye can easily get infected.  Eye infections can be very scary for many, since vision is one of the most important senses.

Following the strict care instructions for wearing contact lenses will be very important when wearing contact lenses.  This means regularly taking the lenses out before going to sleep, rinsing them disinfecting them, and putting them into fresh lens care solution.  Ensuring that your hands are clean and dry will also be very crucial when handling the lenses.

Wearing make-up around the eyes might seem like a good idea especially for someone who had worn glasses for years.  However, you might want to steer away from make-up with lots of harsh chemicals and irritants, which might get into the lenses and cause severe eye infection.  It is wise to apply eye make-up before putting on your contact lenses to make sure that the powder or creams will not get on the surface of the lenses, which can possibly irritate your eyes.

Before wearing contact lenses, always make sure that you will consult with an eye doctor.  The doctor will know whether it would be safe for you to wear lenses and if there are no underlying conditions or possible risks that might be aggravated.  Also, superior quality contact lenses are on the expensive side, but they guarantee both safety and comfort for your eyes.

Not a lot of people might know that there are different types of contact lenses.  They would often be oriented with the types of contact lenses after deciding to switch to this method of vision correction.  The best place to learn about the different types of contact lenses is at the eye doctor’s office or a large eye care store, which have a wide variety of contact lens products in stock.  Contact lenses are designed to suit the user’s needs and lifestyle, so if you are considering contact lenses, you might want to know which ones are perfect for you.

Disposable contact lenses are designed for one-time use.  They are perfect for people who prefer wearing glasses but would like to wear contact lenses for special occasions.  However, they might be a little expensive for people who wear contact lenses everyday.  There are also biweekly disposable contact lenses, which means that they will be replaced after two weeks of use.

There are also contact lenses that can last up to a month before replacement.  They are significantly less expensive than the daily and bi-weekly disposables, but will require more care in handling and maintenance.  These lenses are often recommended for long-time use of around eight to twelve hours per day.

Vision correction lenses also come in different colors, which is very popular among people who want to be a little adventurous with their looks.  Colored contact lenses are a great way to change eye colors without getting surgery.

Extended-wear contact lenses, on the other hand, are designed for people who want to have perfect vision the whole day.  Extended-wear contact lenses can be worn even during sleep, but remember to consult with your eye doctor before you decide to wear them.  Also, remember to throw out the lenses after they have expired.
