Though 1887 is a key year in the invention of the contact lens, its development and history span back hundreds of years, to the time of Leonardo Da Vinci and philosopher and mathematician Rene Descartes. Contact lenses were originally viewed as cumbersome, uncomfortable medical devices to be used in severe cases only. In Germany in 1887, a man by the name of F.A. Miller, who specialized in making artificial glass eyes, inadvertently propelling the invention of the contact lens further. He created a transparent lens. Its purpose was not to help anyone see better by curving the refraction of light hitting their eye, but to cover and thus protect a diseased eye.

A few years after 1887, more inventions were necessary for the contact lens to become what it is today. Though scientists in Switzerland, France and Germany continually shaved the glass lenses down thinner and thinner, the material was still too heavy to wear for any extensive length of time. The contact lenses covered the entire white portion of the eye (the sclera) and the glass prevented oxygen from reaching the eye, causing all sorts of extra problems for the wearer. The invention basically halted by the end of the 19th Century and was not vastly improved upon again until 1936.

In the United States at that time, scientists began to experiment with polymer plastics. They realized plastic was much safer for the eyes than glass. However the problem of oxygen not getting through was still an important issue. In the 1960s and 70s, huge advancements in technology provided the contact lenses we know today: large, soft, porous lenses and small, accurate gas permeable lenses. Today we have more choices than ever!

It was fifty years ago in Bogota, Columbia when laser eye surgery got its start. When Dr. Jose Ignacio Barraquer finally determined a method called keratomileusis, whereby he could change the eye’s refractive power by altering the shape of the cornea. This procedure has since undergone many innovations. Its value lays in the fact that it has laid the ground work for the techniques that now comprise laser eye surgery.

It is true refractive surgery has enabled so many people to function more fully and have a more active lifestyle, with improved vision. Yet it is not the answer to all the eye conditions.

How does Laser Eye Surgery Work?

The corneas purpose is to bend and focus light, this is called refraction, and creates an image on the retina. If the shape of the cornea and the eye are less than perfect then the image created is blurred. This is called a refractive error. This is where glasses and contacts come in, to compensate for the imperfections of the eye.

During laser eye surgery, the eye doctor accurately aims the laser beam onto the cornea making the tissue disappear, without affecting any other surrounding tissues.  Each pulse of the beam removes a microscopic amount of corneal tissue in a painless way.

Different Laser Eye surgery procedures

1. Laser-assisted in situ Keratomileusis (LASIK), in this procedure a flap is created in the stroma, after which the eye doctor then uses the excimer laser to remove material under the flap.
2. Laser Epithelial Keratomileusis (LASEK) is similar to LASIK, except that the flap is created in the epithelium only, instead of through the epithelium and part of the stroma.
3. Epi-LASIK is like LASEK in that the flap is cut only in the epithelium; however, the eye surgeon uses a separator called an epikeratome, to create an epithelial sheet.
4. Photorefractive Keratectomy (PRK) procedure is where the eye doctor will use a laser to remove tissue from the surface of the cornea, with the result that the cornea has a new shape, thus reducing the vision problem.
5. Radial Keratotomy (RK) procedure is where the eye doctor makes incisions in a radial (spoke-like) pattern in your cornea, with the aim of flattening it, to reduce nearsightedness.
6. Astigmatic Keratotomy (AK) is the preferred laser refractive surgery wherein the eye doctor will cut the corneas in areas that are too bulgy. To flatten them to a more regular curve.

Laser Eye Surgery Terms

LASIK stands for laser in situ keratomileusis. In this procedure, the cornea, the front of the eye, is made into a flap, almost like a trap door. The top of the cornea is then folded back, so that the laser can remove a thin layer of tissue. Afterwards the flap is put back in place, and that’s the end of the procedure. This procedure is used to treat nearsightedness, farsightedness and astigmatism and usually takes less than one minute per eye.

PRK - which stands for Photorefractive Keratectomy (PRK), preceded Lasik. Photorefractive alludes to the laser light changing the refraction of the eye. In this procedure laser actually works right on the surface of the eye. There’s no flap. In this procedure, the eye doctor uses the laser to remove tissue from the surface of the cornea. This ablation results in a new shape and usually less than one minute per eye. It is recommended for nearsightedness and mild to moderate farsightedness and astigmatism.

Benefits of Acuvue Contact Lenses

If you are a contact lens wearer, then you are probably familiar with Acuvue contact lenses. Acuvue contact lenses are a great option for anyone of any age interested in wearing contacts because they are available in so many styles, colors, and for different types of vision correction.

However, you might not be aware of all of the wonderful Acuvue contact lenses benefits. And even though there are a wide range of types of contact lenses specially designed for different eye problems, the Acuvue contact lenses are available in many types to fit even the most difficult eye problem. The line of Acuvue contact lenses includes Acuvue lenses for astigmatism, toric lenses, colours, bifocal, daily wear, extended wear, disposables, and the like. Regardless of your eye care needs, you will find what you need with Acuvue contact lenses.

What is the difference between Acuvue and Acuvue2

The basic difference between Acuvue and Acuvue 2 is the thickness of its design. This design difference makes acuvue2 easier to handle. However, if you are currently using Acuvue lenses the difference between Acuvue and acuvue2 may not be sufficient enough for you to switch lenses.

In addition, the Acuvue base curve is different from the Acuvue 2 base curve. The Acuvue lens comes in a base curve of 8.4 and 8.8. The acuuve2 comes in a base curve of 8.3 and 8.7. The base curve is the curve of your cornea and trying on the lenses is the best way to determine if it fits comfortably.

However, the main difference between Acuvue and Acuvue 2 appears to be the ease with which the lenses can be handled. The Acuvue lens that is so comfortable to wear because it is so thin is also difficult to handle, especially for first-time users. It is thin and floppy thus making insertion into the eye difficult. The Acuvue 2 lens is thicker toward the middle making it less floppy and therefore easier to handle.

As with any type of contact lens purchase you must have a prescription to purchase either Acuvue or Acuvue 2 lenses. Also it is important that you do not wear them longer that the stated amount of time, and replace them with new ones as directed. In addition, always follow the instructions for proper cleaning and storage of your lenses. This will ensure good eye health and reduce the risk of complications and/or infections.

As people age, their ability to focus on near and far distances, weakens, hence the need for bifocal contact lenses. The medical term for this is Presbyopia. Once adults hit their 40s, they begin to notice a lack of ability to focus. This is a natural part of ageing and is progressive. In the normal performing eye, the natural lens, which is shaped like a large lentil (about 10 mm in diameter), is attached to muscles which contract or relax to change the shape of the lens.The changing lens shape helps light to be focused in response to the need for clarity. For the adult with Presbyopia, the muscles have begun to lose their flexibility to focus. With this loss, the eyes have a harder time in focusing. Other symptoms of this condition are eyestrain, headaches and squinting. What bifocal contact lenses do is provide patients the balance to look at near and far distances with clarity. This is why bifocal contact lenses have two different prescriptions in them.

The way bifocals work is, the main part of the lenses will have the prescription for nearsightedness or farsightedness, whereas the lower portion of the lens will hold the stronger near prescription for close work.

There are also different designs when it comes to bifocal contact lenses. The traditional design is very similar to the bifocal glasses and ahs two distinct vision corrections, one on top and one on bottom. However, new technology has created the progressive bifocal contact lens and the two different powers are used on the lens in a progressive way. In these types of lenses the eye has to learn which power to use for the distance of the object you are viewing. Some people have problems getting used to this type of lens, while others simply love them and are happy not to have to wear glasses. The only way to find out is to simply talk to your optometrist and give the bifocal contact lenses a shot.

Types of Bifocal Contact Lenses

People who need bifocals to see now have the option of wearing bifocal contact lenses instead of glasses. There are three main types of bifocal contact lenses and two alternative types of bifocal contact lenses:
1. Concentric lenses are shaped sort of like bull’s-eyes, with the near prescription on the inside ring and the far prescription on the outside ring, or vice versa. Between these two main rings, a "multi-focal" or medium prescription ring may be placed if you need it.
2. Aspheric multifocal contact lenses contain both the far and near prescriptions in the center of the lens. The eye will simply ignore the prescription it doesn’t currently require.
3. Translating lenses are set up so that the near, far (and medium if necessary) prescriptions lay in three distinct locations within the lens. Because of this, some translating lenses are truncated or "weighted" on the bottom so that no slippage will occur and mess up the wearer’s vision or disorient him or her.
4. Hybrid Bifocal lenses divide the near and far prescriptions. This means the near prescription could be in the middle of the left eye and the far prescription could be in the middle of the right eye or vice versa, with a "medium" blend in the surrounding circle.
5. Monovision is very similar to hybrid, with one exception: there is no "medium" prescription. The wearer simply learns to use the right eye for items far away and the left eye for items in the foreground.
Between all of the above types of bifocal contact lenses, no matter what your seeing ailment is, you’re covered!

You can be the howling beast with yellow pupils or have a white out pair of contacts as befitting an other worldly alien. With just so many theatrical contact lenses designs in the market, the only limits are your imagination! Yet, it is important to remember that theatrical contact lenses are still medical devices.

Sure, you can wear theatrical or costume contacts even if you do not have a prescription. However, FDA treats theatrical contacts just like all other contact lenses whether they are Plano or not. Since they are still foreign objects that one places in the eyes, they will cause eye infections if you don’t go to a professional for a prescription and to be fitted.

The care and maintenance needed for theatrical contacts are not so different from that given to prescription or non-prescribed contacts.

Here are some dos and don’ts:

• Provided these are properly handled and cared for the color will stay fixed to the lens.
• Don’t use any peroxide or alcohol system to disinfect the lenses, as peroxide may cause discoloration.
• Most costume contacts are warranted against manufacturer defect for 1 year. Ask to find out how long the colors are guaranteed to last.
• Get fitted for these costume contacts. It’s really a sound idea, aside for aside from it being the law, the safety of your eyes is a matter of importance.

You can have the eyes of a jaguar, vampire, the grim reaper, or a zombie. The range of costume contacts nowadays is almost infinite. These theatrical contacts can be hand painted, or you could settle for the mass marketed ones.

The most popular brands of theatrical lenses are WildEyes by CIBA Vision and CrazyLenses by CooperVision. However, there are other manufacturers and distributors from which you can choose your lenses, and the choices are truly amazing.

Theatrical lenses range in price from under thirty dollars to over a hundred dollars for specially designed, hand-painted lenses. Their power can range from a number between +20 to -20, and their base curve can range from 8.00 to 10.0. The diameter can range from 13.0 to 15.0. Other ranges may be available my special order, but this will incur an additional cost. Plano, meaning no power, crazy contact lenses theatrical are also available for those who do not normally wear glasses or contact lenses.

Have you seen star of the movie Riddick Chronicles? Bet you’ve wondered for the longest time where to get his obviously special contact lenses. Films and the costume industry need to employ a lot of special effects to make the character more convincing, and special effects contact lenses, help to achieve these look.

Examples of special effects lenses are: Wild Eyes Zebra, Pool Shark 8 Ball, Starry eyes (have the stars and moon in your pupils), The Stars & Stripes: an American flag, Red Spiral: red with a white spiral, Fire: yellow flames circle your pupil on a red background or Bloodshot: white with red “blood vessels”.   There are Interview with a vampire contact lenses (Lestat’s eyes). If you’re into scary, goth alterna-rock, you can also find crazy contact lenses that look like Marilyn Manson’s eyes (light blue outlines over a huge black pupil and vice versa). Feeling animalistic? Order a pair of dragon’s eyes, which consist of black vertical slits over red or orange irises, or goblin’s eyes, which are yellow with large black pupils.

Not crazy enough for you?

How about “fantascia” (purple stripes!), or black sclera, which covers the entire scope of the eye, leaving no white at all.

Creepiest of all are dead eyes and mirrored eyes.

Dead Eyes are just what they sound like: cloudy, milky film covers the entire eye, creating a sickly, unearthly texture.

Mirrored eyes were made popular by action star Vin Diesel in his movie Pitch Black and Pitch Black’s sequel, The Chronicles of Riddick. Vin Diesel’s character Riddick had eyes that looked like tiny mirrors, reflecting whatever and whoever was in front of him. These mirrored crazy lens contacts are available.

For even more options, consider lenses inspired by the films X-men, X-men 2, and Lord of the Rings, among others. Have fun, be creative and try something wild!

Special effects contacts are made out of soft lenses and worn according to different replacement schedules, such as:

• Daily wear lenses - These lenses must be removed at the end of each day, cleaned and then stored.
• Extended wear soft lenses - designed to be worn for periods up to a month and can be worn even when sleeping.
• Disposable contact lenses - worn for a specified time and then thrown away.

So whether you just like to show your patriotism during the celebration of Independence Day, or change a mood, special effects contacts can do that for you with punctuation.

However, you must never share or swap your costume contacts with anybody. An eye infection caused by improper use can lead to blindness.

Get fitted for your prescription, for it the contact lenses don’t fit your eyes properly, it could lead to serious eye problems, scarring, abrasions and infections.

As long as you follow the rules in buying special effect lenses and take care of the ones you have, you won’t have to worry a thing about wearing them. So make sure you go to a trained eye professional for your contacts.

Astigmatism and toric contact lenses

Astigmatism is a very common vision problem, yet many people remain unclear about what it really is. Corneal astigmatism, the most common type of astigmatism, simply means that there is an irregularly shaped cornea. Depending on the severity of the irregularity, symptoms can present as mild blurriness to headaches or eyestrain to severe discomfort and visual difficulty. A less common type of astigmatism results from an irregularly shaped lens. Known as lenticular astigmatism, this condition originates behind the cornea. Most cases of astigmatism, regardless of their origin, are correctable. Toric contact lenses are one option for coping with this condition. Other options include the use of eyeglasses or even surgery (in extreme cases of astigmatism).

Toric contact lenses, lenses designed with two powers, bring clear sight to those with astigmatism. Although the lens is designed specifically for astigmatic people, they can be soft or RPG like other lenses out there. In addition to the different angle curvatures they possess (to correct near-sightedness or far-sightedness plus astigmatism), they also contain a stabilizing mechanism so that they don’t move around when one blinks. Toric contact lenses are even tinted so that they are easily located while in their solution. They do not, however, alter eye color.

What causes astigmatism?

Usually, astigmatism is hereditary although injury can cause this condition. It is very important to have your eyes screened. Children, too, can be astigmatic which can affect their performance in school as well as sports. It is essential to remember, however, that astigmatism is easily treated and compensated for under the supervision of an eye doctor.

Toric Contact Lenses

One option is that of soft torics; they come in either disposable or non-disposable materials. Another option is the hard torics. This is because the material is made of rigid gas permeable (RGP) lenses, thus they offer more oxygen and can compensate for a majority of astigmatic cases, especially the more severe cases.

In order to understand how toric contacts help compensate for your blurry vision, it is important to know the effect of astigmatism. A normal cornea is shaped like a dome. Light rays focus to a point in the back of your eye, and you get a sharp image. However, with astigmatism the cornea is incorrectly shaped like a football. The rays of light then hit two points in the back of your eye.

Toric lenses return to the same position even after a person blinks. This is because the lenses have thin zones and curvatures created at different angles. There are also special mechanisms that allow the lenses to remain stable. So even if the wearer blinks, the lenses will rotate but returns to the same position, providing sharp vision.

It is thought that a majority of people have a mild case of astigmatism. Also that it affects more women and even children can have it at an early age. The causes of astigmatism are many. It can be hereditary, partly environmental or even due to chronic eye rubbing. People who have diabetes can experience changes in the shape of their corneas.

What’s good to know is even if this eye condition is severe can be corrected by laser surgery. While for those with milder cases, a pair of eye glasses or toric contact lenses will help them look at the world with a crisp vision.

In addition to correcting astigmatism, toric soft lenses are available in a variety of colors to enhance or change your eye color as the mood suits you. These soft, toric colored lenses are usually conventional lenses meaning that they are not disposable. However, some manufactures offer a variety of soft toric lenses that are replaceable every three months, or even daily, depending upon the type of lens you purchase.

Soft toric lenses are a relatively new innovation in the long history of contact lenses. Leonardo da Vinci was the first person to conceptualize this type of vision correction device, but he was not the last. Following a centuries long development process, the toric lens was approved for sale in the United States in 1978.

If you have astigmatism, and have been told that you cannot wear soft contact lenses, toric contact lenses may be the answer. Toric contact lens rating websites can be found on the internet with information about manufactures, prices, and color options.
