Contact Lenses Can Bring Focus to Life
Glasses can be cumbersome and uncomfortable, which is why contact lenses are a perfect solution to traditional eyewear. Eyeglasses can create discomfort in the lobes of the ears, as well as on the bridge of the nose. Contact lenses are a means to eliminate these problems permanently. In terms of current history, the major breakthrough with contact lenses dates back to 1959, when the first “soft lens” was introduced. It was used in many countries through the 1960’s, but didn’t reach the states until later. In 1971, the FDA (Food and Drug Administration) approved the material known as “soflens.” In 1999, silicone was introduced as a material for the uses of daily contact lenses. This was an important breakthrough because silicone has a high level of oxygen permeability, creating the same comfort that was found in the previous contacts used since 1971. The benefit of oxygen permeability equates to longer comfort. Daily contact lenses were

extended to stay in overnight, meaning less maintenance. CooperVision has taken the silicone lens a step further with a polymer lens. Polymer is defined as, “A long or larger molecule consisting of a chain or network of many repeating units, formed by chemically bonding together many identical or similar small molecules called monomer.� This translates as to having a high oxygen permeability rate, allowing greater comfort with wearing daily contact lenses.

Switchover from Glasses to Contact Lenses
Many people have been wearing eyeglasses for years, but may feel it is time to make the transition. What a joy to remove the glassed from the face for the very last time, never having to worry about where to keep them ever again. The same clear quality that was revealed by glasses can be seen through the eyes with contact lenses. Better yet, daily contact lenses provide a wider field of clear vision, covering the peripheral areas as well. The transition does not happen immediately, as it may take about a week for eyes to fully adapt to wearing contact lenses. As little as six hours of wear may be recommended by an individual’s optometrist with a progression of two hours per day for as long as six days. After the sixth day, the daily contact lenses can be worn without concern for the entire duration of waking hours. Again, it is important to follow the guidelines of an optometrist for proper care and adaptation.

Daily contact lenses have made some major breakthroughs in the past 50 years, innovations that have lessened the discomfort of wearing glasses. Contact lenses can also instill self-confidence that cannot be gained by wearing glasses. The transformation of the market from hydrogel lenses to silicone lenses has offered even greater comfort to one of the most important senses of the body. Vision is a gift that those who wear daily contact lenses do not take lightly. Just because an individual has a vision problem doesn’t meant there has to be discomfort or high maintenance involved. The best solution to date is with polymer lenses.

The Purpose of Wearing Contact Lenses
Contact lenses are an ideal alternative to wearing conventional eyeglasses for many reasons. Comparatively speaking, they can both provide the same function for their fundamental purpose. Daily contact lenses go a step further than simply providing the wearer with better vision. The comfort in wearing daily contact lenses provide relief in knowing that clear vision is not dependent on locating a pair of glasses. Even more recently (within the past 30 years), the maintenance of daily contact lenses has been reduced dramatically. No longer is it necessary to provide an external source of hydration due to dryness of the contact lenses. The recent innovation of silicone contact lenses offers less maintenance with a higher level of oxygen permeability. One of the more recent styles is made of 48% water!

Reasons to Wear Contact Lenses
1
The fundamental reason to wear daily contact lenses if for proper vision for those who are impaired or have less than perfect vision. Clear, focused vision can completely change an individual’s perspective on life. No longer will he or she squint to read road signs, or more importantly, the newspaper or a book. Contact lenses offer a wider field of vision, reducing peripheral uses created from eyeglasses.

Self-confidence is another reason many individuals switch from eyeglasses to daily contact lenses. Wearing eyeglasses have been reported to create a complex in relation to self-image that can be eliminated by wearing daily contact lenses.

Contact lenses can correct the problem of astigmatism. Astigmatism can accompany near or farsightedness, occurring from an abnormally shaped cornea. Specifically, toric contact lenses can actually correct the problem of astigmatism in many cases.

In the past, contact lenses were expensive, but the price of them has become competitive and affordable. With the possibility of glasses breaking or being lost, daily contact lenses can cost less than eyeglasses.

Comfort is a popular reason many individuals choose contact lenses over eyeglasses. Problems with discomfort can occur in regions of the nose where the bridge is used to support the glasses. Also, pull from the arms on the lobes can also cause irritation and minor pain. Today, contact lenses can be inserted once, and then forgotten without even feeling them in the eyes.

Reasons to Wear Contact Lenses
Contact lenses serve many functions for many individuals. It has been estimated that over 125 million individuals across the globe prefer to wear contact lenses over eyeglasses. At the rate of innovation, that number may grow. The importance of clear vision cannot be underestimated especially if it involves personal safety, as well as the safety of others. Consider the example of driving, when focus and clear vision is most important. Contact lenses can prevent an accident or better inform the driver with the ability to read the road signs. When it comes to proper vision, there is no replacement for the security and confidence of knowing that it will not be compromised. There are many reasons to wear contact lenses, as they are a tool that will aid in all facets of life.

Toric Contact Lenses A Tool for Clear Vision
There are many types of contact lenses available for the purpose of corrective vision; ones that can be ideal for treating many conditions are known as toric contact lenses. Toric contact lenses are contact lenses that are specifically made with two curvatures that can be used to treat astigmatism, as well as myopia or hyperopia.

Astigmatism Is a condition where the cornea may not be completely round, causing problems with vision. In some cases, the condition may only occur in a single eye. In this case, the optometrist or eye care practitioner may prescribe a toric contact lens for one eye and a corrective prescription for the other. Astigmatism normally affects those who are middle aged, and it is a condition that can become worse with time. It can ultimately lead to blindness, if not addressed. With the average age of Americans on the rise, this will be a growing problem that will need to be addressed with more frequency.

Myopia Is also known as near-sightedness, can be a condition that occurs as a result of astigmatism. It can affect one or both eyes. In this case, toric contact lenses can be prescribed to correct the vision problem. Specially designed to remain stable on the eye, toric contact lenses provide an ideal solution to the condition of myopia.

Hyperopia Is also known as far-sightedness, is another condition that occurs due to astigmatism. Toric contact lenses replace the function of the natural lens, compensating in areas where there are issues with blurriness because of the abnormal bend of the natural lens. With conditions of myopia or hyperopia, the lens is curved specifically to

Toric contact lenses are offered in the form of soft and rigid gas permeable, just as regular contact lenses. One of the main differences between normal contact lenses and toric contact lenses is that toric contact lenses cannot move all around. They have a distinct upward and downward movement, but must remain stable due to the orientation of the vision problem corrected. One of the newer innovations is a long-lasting design of toric lenses that allows the wearer to insert the contact lenses for a period of 30 days. These contacts lenses are made of silicone and contain the ability to hydrate the lens. Hands-free and worryfree options give the wearer complete confidence in making a transition from traditional eyeglasses to toric contact lenses. A revolution in eyewear, new toric lenses are a tool that provides clear vision without any problems with hydrating. A few extra hours in the optometrist’s chair is definitely an investment that is worth it.
