Non Prescription Colored Contact Lenses

Wearing non prescription colored contact lenses can be fun, exotic, and may be more common than you think. As far back as 1508, contact lenses were an abstract construct in at least one person's mind. Of all people to have this idea was the infamous Leonardo da Vinci. Da Vinci detailed descriptions and drawings of how a person could alter the power of the cornea by submersion of the eye into a bowl of water. His idea, of course was at least 300 years ahead of its time. In the 1820's, an English astronomer, named Sir John Herschel, proposed techniques for grinding and fitting a lens to conform precisely to the surface of the eye. In order to do this most accurately, Herschel suggested that, first, a cast should be made of the eye so that the final product would conform exactly to the person's eyeball. In 1888, a physiologist in Zurich, by the name of A. E. Fick, put Herschel's original idea to the test by developing a pair of lenses for himself. Because he used glass, the lenses were extremely heavy for the eyes. He was only able to wear them for a total of 2 hours because of their weight and the fact that oxygen could not get to the eye. Nevertheless, non prescription colored contact lenses would not have been possible without those first stages of contact lens development.

There were many false starts and do overs throughout the next century. Even with all of the research and activities going, until the 1930's, the only type of lens that was readily available was the glass-blown scleral lens; not quite the right material for non prescription colored contact lenses. Various chemists and eye specialists became aggressive in the pursuit of a more appropriate material for use in the development of contacts. Experimental lenses were made with numerous materials. It wasn't until 1938 that a new material called polymethylmethacrylate (PMMA) was determined to be a much better material because of its low density. Though this material wasn't perfect, it worked fairly well. In 1949, corneal lenses took the place of the original scleral type. This lens was more akin to the type and size of lens that is used in non prescription colored contact lenses. Because of this advancement, mass appeal developed through the 1960s. The contact lens became even more intricate with improved manufacturing technology; giving rise to silicone hydrogels. This new lens technology had extreme oxygen permeability. The level of comfort experienced by wearers of the silicon hydrogels, was unmatched.

After such a major breakthrough, contacts became all the rage. The price of contacts fell considerably. Those people who would have never considered trying them, began to question their doctors. Also, this advancement in technology, catapulted a new industry of non prescription colored contact lenses. People who would have never considered putting something in their eyes to enhance their beauty or change their appearance, began to gobble up multiple pairs, in various shades. It is estimated that a full 2 percent of the population (approximately 125 million people) actually wear contacts. Of that amount, nearly 38 million of the wearers are in the U.S. Contacts are less affected by weather and generally do not steam up when a person goes from one temperature extreme to another. They also provide a clearer field of vision in that there are no arms that hold the lens to your face; to block your peripheral sphere. Lots of people, who need corrective lenses, choose to wear contacts so as not to alter personal appearance or because of the fact that they are more practical than glasses. But, there is also a large percentage that choose to wear non prescription colored contact lenses for purely cosmetic reasons. These people want to alter their appearance.

"Let all the nations be gathered together, and let the people be assembled: who among them can declare this, and shew us former things? let them bring forth their witnesses, that they may be justified: or let them hear, and say, It is truth." (Isaiah 43:9) They are used, like make-up is used, to enhance one's appearance. The available colors go from regular eye colors to extreme colors and shapes; most appropriately worn on Halloween. Some people use colored contacts to color coordinate with their apparel. Others use these contacts as part of a make-over. Because non prescription colored contact lenses tend to be opaque, the natural color of a person's eyes, doesn't really matter. Light blue eyes can be turned into pools of aqua. Dark chocolate eyes can become brilliant turquoise. Hazel eyes can be made jade.

Since 1999, the silicone hydrogel has become the standard in contact lens technology. These lenses are far more comfortable. Yet this comfort comes with a price. The actual cost of a lens is less per lens, but they must be replaced much more often than the rigid lens. Some companies produce contacts that are called daily wear. You wear those lens for one day and throw them away. There are others that are meant to be used for a full week at a time; and up to two weeks max. Whether a person is wearing them for corrective or cosmetic purposes, all contact lenses are medical devices. They are to be worn under a doctors care. This is also true for non prescription colored contact lenses; as well. A person is apportioned only one set of eyes. It is the most valuable of all our senses. People can have fun and make them exotic; if they wish.

Non Prescription Contact Lenses

While obtaining non prescription contact lenses is possible, it may not be in the best interests of the consumer's visual health. Anyone who has less than perfect vision is going to be dependent on glasses or contacts to some degree. As with any other area of health, consulting with a medical professional and receiving regular care is wise. Seeking out ways to purchase contacts online without a prescription may mean that the patient is ignoring their vision for the sake of saving money. Most web sites that originate in the United States so not permit the sale of non prescription contact lenses. There are, however, a number of European and British sites the will allow visitors to order contacts without prescriptions. The danger of ignoring regular vision checks and continuing to order lenses from an old prescription is plain. Older prescriptions may not offer the needed amount of correction as time passes and the patient's vision changes.

It is also important to consistently visit an eye care professional in order to detect other health issues in a timely manner. Why take chances with something as important as healthy vision? If the motive for ordering contacts without prescriptions is one of economy, the consumer should keep in mind that they may end up paying a higher price in the long run. The costs of contacts on many of these nonprescription sites can be quite high. Additionally, the medical costs that are associated with an eye infection or other vision related medical conditions can be extremely costly. The many safety issues that can be associated with selling non prescription contact lenses has made many vendors hesitant to offer these products without qualified medical oversight. Even contacts that do not include any kind of visual correction will require prescriptions that measure the size as well as other properties of the individual's eyes.

Many consumers wish to order non prescription contact lenses for cosmetic purposes. If the desire is to artificially change the color of the eyes through contacts, it is possible to purchase these lenses without prescription. This may not be a good idea, however. It is important to keep in mind that the eyes are very sensitive. Inserting unregulated contacts can lead to serious vision problems. For this reason, these products should be obtained with the guidance a qualified medical professional. Poor quality contacts can be uncomfortable for the user. Color contacts may also contain paints that are toxic in nature. While it can be exciting and glamorous to be able to change the appearance of the eyes, using non prescription contact lenses that are not safe can be a major mistake. But under the supervision of a qualified doctor, contacts in a variety of colors can be fun and flattering. Colored contacts will generally fall into one of two categories, enhancement or opaque. For individuals with eyes that are light in color, enhancement contacts can be used to add a little spark and interest to the natural color. If a complete change of color is desires, opaque contacts are needed. The darker the natural eye color, the harder it can be to change the color while still allowing the patient to see properly.

For some customers, contacts are not needed for everyday life. There may, however, be special occasions that call for cosmetic contacts that offer special effects. In these cases, non prescription contact lenses may work well for extremely short term use. These lenses may be available in a wide variety of styles and features. Whether the consumer is interested in a cat eye effect, or something a little frightening for a costume party or theater production, such products are widely available. Called plano lenses, these contacts may also feature a glow in the dark factor, swirls, flames, flowers, spirals, flags, hearts, stars, and alien effects. Used as a fashion accessory, these products can be fun and creative. The user should always keep visual health in mind, however. If the non prescription contact lenses are causing pain or are uncomfortable, they should be removed before the eye is damaged. No special effect is worth causing serious damage to the eyes. This is particularly true if the special effect contacts are only meant to provide a short term alteration. Keeping the eyes healthy has to be the top priority. The Bible tells believers to turn to God for mercy and to hope in Him. "Let thy mercy, O Lord, be upon us, according as we hope in thee." (Psalm 33:22)

The first step in obtaining non prescription contact lenses is to schedule a visit to an eye care professional. This is true for those who need visual correction and for those who don't. A professional in this field can measure the curve of the eye as well as the diameter of the lens that will be needed. If possible, the consumer can save money by asking the physician to make these measurements during an ordinary visual check up. Even without a corrective medical prescription, these measurements will be needed before most vendors will fill an order for cosmetic contacts. With these measurements in hand, the next step is to shop around for the best price. It may also be wise to double check with an optometrist before making a purchase. This professional can advise the individual on the overall quality of the products that a particular company might offer. With care and professional advice, it is possible to find attractive contacts at reasonable prices.
