A convenient and a smart substitute for spectacles, contact lenses help in eye focusing in the same manner as spectacles do. Contacts are small visual devices made with curved pieces of plastic shaped in a way to adapt to the wearer’s eye.

Conceptualized first by Leonardo Da Vinci, there has been many changes and modifications made to the original idea of contacts. They provide an artificial refracting surface to the human eye and are used to correct vision problems like myopia and hyperopia.Besides, contact lenses can be used for therapeutic and cosmetic reasons. There are almost 35million wearers of these lenses today in the USA alone.

Features of Contacts

Made from different types of materials – soft and rigid – and come in a variety of designs and colors which disposable, colored, astigmatic, aphakic, presbyopic and keratoconic lenses. However, the most important thing is the initial fitting and follow-up care essential to maximize benefits of comfort, vision and tissue integrity.

Advantages of Contacts

There are places where the contacts score above the spectacles. Unlike the spectacles they are not in the danger of slipping off, getting wet, or fogging up. Moreover, they can correct several eye problems which spectacles cannot.

o Contacts are more comfortable for hypermetropiac people and people with their cataracts removed since they provide a better and even vision.
o For people with damaged corneas through diseases or injuries can have more improved vision through contact lenses.
o In case of sportsmen, these lenses are more convenient since spectacles may be a hindrance in their job.
o Contact lenses give a better side-vision as compared to glasses.

Uses of Contacts

o Besides the primary function of correcting myopia or short sightedness, contact lenses also rectify visual problems like hyperopia, astigmatism, presbyopia and aphakia.
o Rigid lenses correct irregular corneal trauma.
o Soft lenses are used as bandages for conditions like bullous keratopathy, recurring corneal erosion and also increases comfort, vision and postoperative wound healing.

The Main 2 Types

o Soft lenses-These are made of hydrophilic plastics and absorb liquid and should be kept moist for softness and easier molding to the corneal surface. These are extremely comfortable and are used by majority.
o Rigid contacts RPG)-Easier to maintain these are made of which permit oxygen to pass through to the cornea. These have replaced the original hard lenses, or PMMAs, used earlier which did not allow oxygen to pass to the eye.

Eyes are the most expressive part of our body…no wonder they are called “the mirror to our souls”. Beautiful eyes add to the beauty of the face…they are often the most sorted after part of a woman; a pair of eyes that can make their admirers drool over them!

I’m sure each of us has a lovely pair of eyes, and would love to show them off! The hindrance to this is of course, the pair of specs we are often forced to wear, spectacles are a much needed tool no doubt, but they often hide the prettiest feature that we possess.

Not only that, wearing specs means that we cannot swim, or play a vigorous game of tennis, or even dance. Simply put, every activity that requires us to move about too much is restricted because of the specs. You may have often heard your doctor mention contact lens, the truth is that many people believe it’s not too safe!

They fall off while washing your eyes, they may be very irritating if dust enters your eyes, and on top of this, the constant burden of washing your lens every day and before every replacement. This is why most people think that even though contact lens is popular, specs are a much safer choice. But we have news that’ll put all your fears and reservations at rest.

Contact lenses can be an easier, safer option, provided you choose wisely according to what you’ll be comfortable wearing. Contact lenses are made differently for different needs, so pick out the one that best suits your requirements, you’ll find that they are not only comfortable, but they undoubtedly are the best accessories your eyes can ask for! To make your search less tedious, here’s a list of the various types of contact lenses you can choose from:

o The first type of contact lens we’ll talk about is disposable lens. You must have guessed from the name itself that these are ones you can throw off once you’re done with them, or if you find they are not suiting you. Of course, this means that you won’t have to clean them at regular intervals, you won’t have to fret if you suddenly discover they’ve fallen off. While you’re using them, you’ll have no trouble maintaining them. Now lets move on to the vast range of contact lens that fall under the category of disposable lenses…but are suited for different needs.

o The next category is daily disposable lens. It’s evident from the name that these are lenses you can dispose off everyday, that is, they can be used once, so you’ll have to wear a new pair everyday, and there’s absolutely no chance of infection. They don’t require disinfection, cleaning solutions, and all the trouble we associate with having to wear contact lenses. This type of lens is also very useful and well suited for those who normally use specs but reserve contact lenses for special occasions.

A slight variation of this kind of lens is sports lenses. These lenses are just right for those who spend a lot of their time outdoors in activity. Spectacles are of course a major difficulty for those who play physically demanding sports like tennis, football or swimming. These contact lenses make you completely free of that burden on your eyes and ensure that you can perform your best at all the events. They are also very useful if you’re going mountaineering or rock climbing, by wearing these, if you can wear a sunglass over it, you’re all set to take on the hills, and your eyes are all protected! Like the daily disposable contact lens, they too can be thrown away after a single use, and requires no disinfection and changes!

o Moving on, the next type of disposable contact lenses available is the monthly disposable variety. The only way they are similar to daily contact lenses is that they can be disposed off…but the deadline is a month instead of a day. These require some more care, as they have to be cleaned and disinfected everyday for one month. Very similar to these are contact lenses that can be worn over a period of a year, and can be disposed for a new pair thereafter. Of course, this type of lens is most suited for those who use contacts on an everyday basis and not occasionally. You need to be used to the procedures of using and maintaining lenses to use these.

Before you buy the lenses, there’s another last thing that you’ll need to keep in mind. Whether you’re wearing contact lenses on a regular basis, or occasionally, it’s extremely important that you keep a spare pair of lens or specs within reach. Much as we admit that contact lens is an easier option, you should have an extra pair of specs just in case you need them.

Always keep them with you even if you’re away from home, so that you’re not dependant on a single pair of lenses. Of course, since most lens users are ex-specs users, they never leave home without their trusty old pair of glasses or an extra pair of lens that can see them through if the existing pair fails!

Contact lenses have completely changed the way everyone looks at eyewear. Now, people have the power to choose their look and aren’t forced to wear glasses if they don’t want to. People choose contact lenses for the various advantages that they have over framed glasses. Glasses don’t always stay put on you nose. They are also heavy to wear and often create pinch marks on your nose. There is also a problem with glares when you are wearing glasses. And along with all this, you need to have special lenses or an extra pair to protect you from the sun when you go out.

With contact lenses you have none of these problems. You are free to wear whatever you want. You don’t have to think about the glasses not looking good with your dress or style. It will stop narrowing your field of vision and you can freely look around without moving your head.

Contact lenses have come a long way since they were first introduced in the 1950s. Back then, they were made of hard glass and caused many problems. It was uncomfortable to wear. It could also scratch the eye during removal. Then polymer based lenses were introduced. While these were more comfortable, they also cut off the oxygen supply to the eye.

In grade school as a child most of us have heard or have verbally teased another school mate who wore glasses by calling them,” Four Eyes”. This should not be so but it does happen. Luckily the poor innocent victim whose vision requires assistance can fix the problem by getting rid of those glasses and exchanging them for contact lenses. Today’s contact lenses are easy to get and easy to use. However, contacts need to be cared for daily to keep them sanitized and eye friendly.

One convenience of regular glasses is that they never actually make contact with the eye. So if you pumped gasoline into your car and place the glasses back on any residue of the toxic gas transferred to the hands has no opportunity to come in contact with the eye. If you are wearing contacts more caution must be exercised. Before putting in or removing contact lenses you should cleanse the hands with soap and water. On top of that you need to dry the hands thoroughly to remove any soap or chemical residue to avoid causing the contacts to be contaminated when being handled. A little soap film on contact lenses can cause the eye’s to experience a very uncomfortable burning sensation and even actually damage the organ.

Contact lenses normally are easy to use but sometimes they just don’t seem to want to cooperate. When this happens be patient and restrain from forcing them into place. With cleaned hands simply put an appropriate solution in the cupped palm of one hand and with the other carefully rub the contact lens in the solution. When done doing this give the lenses a second wetting with the solution and the contacts should slip over the eye easily

If you are not using your contact lenses be sure they are immersed in fresh solution. This is especially necessary to do when the lenses are soaking overnight while sleeping. While you sleep the solution is properly removing the protein out of the porous lenses. Not doing this with the contacts when not in use can cause physical damage to the eye the next time they’re used. If after following the right procedures for caring for your contact lenses the eyes still sting when using them you should find a different solution product. Doing this in most cases stops the problem of burning and irritation to the eyes. On windy or extremely dry weather days it may be necessary to rewet the eyes. Contact lenses can dry out and feel uncomfortable. Just remember to keep a small bottle of saline solution with you and apply a few drops to the dry lenses and the eye and business can go on as usual.

If you’re afraid to try contact lenses its understandable. The idea of putting some foreign object in your eye seems contrary to nature. You’ll only feel this way before your optician explains and shows you how to use them. If they do their job right the fear of contact lenses will disappear. The only thing you have to worry about when using contacts is deciding how many mirrors to purchase. Because once you stop being a “four eyes” your ego will swell and force you to enjoy viewing the glamorous new you often.

Contact lenses, ever since they were introduced into the market, have been a revolution in the eyewear industry. Almost single-handedly, they have made glasses redundant. Although some people still swear by glasses, their numbers are steadily dwindling, as more and more people discover the wonder of contact lenses. As the name indicates, such micro-lenses just stay softly in contact with your eyeballs, without slipping off like glasses, or even without breaking like conventional glasses do.

Contact lenses free you from wearing glasses. For most people, that is their single biggest advantage, as it frees them from the task of wearing ungainly eyewear with thick, clumsy lenses. For no matter how high your power, far or near sighted, they ensure that they are all reduced to very small, paper thin lenses. They are especially helpful if you are into sports or lead a hectic, outdoors life in general. There is no possibility of suffering from any difficulty, a la glasses.

The best part is, contact lenses are available in all types. There are bi-focal contact lenses, and also colored lenses, which have had a big impact on fashion in recent times. You should remember, however, to contact your physician before you decide to put on those colored lenses for fun and fashion, or any lenses for that matter. This is because, although these have absolutely no side-effects, some people may be allergic to wearing them. In that case, your eyes start watering, irritations may occur, and sometimes, these can also be fatal, leading to permanent sight-loss.

Another significant reason why many physicians today advise the wearing of contact lenses is, and this is especially true for children, they help in preventing worsening of eye-sight, i.e stops your ‘power’ from increasing. It is a fact confirmed by medical surveys that the use of contact lenses helps in stabilizing the vision of those with high ‘power’- hence it ensures that a certain level is maintained. Compared to that, conventional specs do little to retard such worsening. If you do not want to go in for surgery at a later stage – which involves a great amount of risk, since it is your eyes we are talking about here – you would do well for yourself to get ‘contacts’, literally!

Finally, you should know that contact lenses are made from different materials are classified accordingly – soft, hard, gas permeable, and rigid gas permeable (RGP). You need to consult your physician to decide which would suit your needs the best. In general, soft lenses and RGPs are the most commonly used ones. There are durable lenses, lasting up to 1 year, and there are also disposable lenses, which can be changed every week, or every month, depending on conditions of usage, and also on the price range.

So, now that you know all, or at least, a lot of things about contact lenses, its uses and types, you can make a wise choice. Choose the right contact that would not only suit your looks but also suit your personality. Bring about a difference in your appearance.

If you’ve ever seen a movie about vampires or monsters where people have oddly colored eyes, cat eyes or other types of eyes, you’ve seen special effects contact lenses in action. These contact lenses, rather than correct sight (though some are actually prescription as well) create a special effect in the eye.

These lenses come in a wide variety of types and are available to the general public. While certain special effect contact lenses are designed especially for a movie, you can also expect to find similar ones on the public market within a few months after the movie is released.

Styles of Special Effects Contact Lenses

There are so many different types of these contact lenses that you can really get any look you want. For some people, this means simply changing their eye color. Light eyes can easily become any color you like, from green to blue to brown or even purple. Dark eyes are more limited in the options, but can usually go with black, dark green and sometimes a dark blue or purple.

For more zany effects, there are plenty of other options. Everything from the very scary cat eyes or red hellish eyes to more benign smiley face contacts can be had. There are circuit board contacts, zebra or tiger stripes, and just about anything else you can imagine. There are even images available to place in your eyes, so you can have a tiny flower or mountain scene actually placed on your eye.

Not every special effects contact company will provide all of these options, but you’ll find that the catalogs of effects are quite surprising.

Why Use Special Effects Contact Lenses

For some people, it’s a matter of feeling better about themselves. If you don’t like your eye color, for example, being able to change it to something you feel is more acceptable can be a good boost for your self esteem.

For others, it’s about conveying who they are inside. Science fiction fans, for example, might want to use eye color and styles that represent their favorite sci-fi characters. Those who are fascinated by vampires may prefer vampire style eyes while those interested in technology might want to surprise their friends with circuit board eyes.

Special effect contact lenses are usually only used a handful of times. Some are actually one use only and they are completely disposable. This type of contact lens is ideal for Halloween parties or other disguises. If you are in need of a costume for a play, special effect contacts can also come in handy, as with role playing activities.

Should You Use Contact Lenses for Effect?

Not everyone is interested in using contact lenses. If you have eye problems, you might want to talk to your eye doctor before trying special effects contact lenses. They usually aren’t meant for long term use and if you aren’t accustomed to wearing contacts, it is better not to leave them in for very long. Two or three hours is the recommended period for beginning contact lens wear.

If you already use glasses or contact lenses, you can get special effect lenses as prescriptions, too. So, they would just replace your regular contact lenses. Otherwise, glasses can be worn in combination with the contact lenses, though some people find this ruins the effect they are going for. For simple color changes, however, it works fine.

Special effects contact lenses can be a lot of fun to play around with, but they are also very practical if you need a new look. Check out the different options available and choose the ones that suit you.
