About Focus Contact Lenses?

Contact lenses have become so popular that people have been trading lenses among themselves, particularly in the teenage population. This can be extremely unsanitary and dangerous to one’s eyesight.

Focus on contact lenses, that don't fit correctly or are used by more than one individual can cause serious eye infections, sometimes resulting in permanent eye damage, or worse.

The History Of Contact Lenses

1508 Leonardo da Vinci sketches and describes several forms of focus contact lens.

1632 Rene Descartes of France suggests the corneal contact lens.

1801 Thomas Young develops Descartes' idea -- a quarter-inch-long, water-filled glass tube, the outer end containing a microscopic lens -- and uses it to correct his own vision.

1827 English astronomer Sir John Herschel suggests grinding a contact lens to conform exactly to the eye's surface.

1887 Glassblower F.E. Muller of Wiesbaden, Germany, produces the first eye covering designed to be seen through and tolerated.

1888 Two independent researchers, A. Eugen Fick, a Swiss physician, and Paris optician Edouard Kalt, almost simultaneously report using contact lenses to correct optical defects

1929 Joseph Dallos, a Hungarian physician, perfects methods of taking molds from living eyes so that lenses can be made to conform more closely to individual sclera.

1936 William Feinbloom, a New York optometrist, fabricates the first American-made contact lenses and introduces the use of plastic.

1945 The American Optometric Association (AOA) formally recognizes the growing contact lens field by specifying contact lens fitting as an integral part of the practice of optometry.

1950 Dr. George Butterfield, an Oregon optometrist, designs a corneal lens, the inner surface of which follows the eye's shape instead of sitting flat.

1960 Otto Wichterle and Drahoslav Lim experiment with contact lenses made of a soft, water-absorbing plastic they developed.

1971 The soft lens became available for commercial distribution in the United States.

1978 The first toric contact lens was approved for distribution in the United States.

1979 The first rigid gas permeable (RGP) contact lens made of co-polymers PMMA and silicone became available for commercial distribution. Many silicone-acrylate lenses are now available.

1980 A tinted daily wear soft lens became available for commercial distribution.

1981 Extended wear soft lenses became available for commercial distribution.

1982 Bifocal daily wear soft contact lenses became available for commercial distribution.

Focus on contact lens

There are several types of contact lenses designed to fit the most common vision conditions. Following are brief descriptions of these conditions:

Myopia(Nearsightedness)

Myopia is a condition which occurs when the eyeball is too long, or the eye's focusing mechanism is too powerful (cornea and lens), and light rays are focused in front of the retina. People with this condition can see clearly up close but not at a distance. An estimated 30% of Americans are nearsighted to some degree. Lenses to correct this common condition are thinner in the center than on the edges to help redirect light rays to the retina, and are called "minus" or concave lenses.

Hyperopia (Farsightedness)

Hyperopia occurs when the eyeball is too short from front to back, or the eye's focusing mechanism is too weak, causing light rays to be focused behind, rather than on the retina. People with hyperopia have difficulty seeing objects close up. An estimated 60% of Americans are farsighted to some degree. In order to correct this vision problem, a convex, or "plus" lens is prescribed. This lens is thicker in the center and thinner on the edges.

Astigmatism

Astigmatism is characterized by an irregularly shaped cornea that causes light images to focus on two separate points in the eye, creating a distorted image. Symptoms range from visual discomfort in mild cases, to severe blurring and distortion similar to a reflection in a fun-house mirror. Contact lenses designed to provide astigmatic correction are fitted for each individual. The misshapen cornea is precisely measured and special toric lenses are used to direct light rays to one spot on the retina. There are more than 60 thousand different toric prescriptions available, offering the nearly 71 million Americans affected by astigmatism an alternative to eyeglasses. Rigid Gas Permeable (RGP) lenses, due to their firm design, offer a high degree of corrective ability for this condition and, in many cases, do not require a complicated toric design due to their ability to compensate for the irregularly shaped cornea.

Presbyopia

This is a condition that occurs as the eye’s lens grows older and begins to lose some of the elasticity needed to switch focus between viewing near and far objects. Also known as "aging eye," presbyopia affects most people around the age of forty, even though its onset can occur as early as age ten. As the eye's lens continues to lose its elasticity, the eye takes longer to adjust between objects -- such as the road and the speedometer. Half-glasses or bifocals used to be the only answer for people with presbyopia. Today there are a number of contact lenses that can correct this condition, including multifocal contacts and specialized fitting techniques such as monovision.

Color Disposable contact lens

Colored contacts have become so popular that people have been trading lenses among themselves, particularly in the teenage population. This can be extremely unsanitary and dangerous.

You don’t have to have vision problems to wear colored contacts lens. Some people simply want to change their eye color, as colored contacts can be great fun. It is essential, however, that contact lenses be professionally fitted. Contact lenses are a medical device regulated by the FDA.

New technology in contact lens wear and care is making contacts the easiest and most efficient option for vision correction. There are new daily wear and disposable lenses, and contacts for those of us with astigmatism and other vision problems--patients once excluded from the benefits of lenswear. And if you've always secretly wanted to change those baby blues to gorgeous greens, contacts can provide that convenience as well.

As any athlete can testify, contacts are ideal for an active lifestyle. Many sports enthusiasts are finding that contact lenses are more practical than glasses because they offer improved depth perception and enhanced peripheral vision. Additionally, contact lenses won't steam up from perspiration, and they don't smudge or get foggy if you go from cold to warm temperatures.

The flexibility and convenience that contact lenses provide are leading more and more people to contacts as science provides us with greater options in contact lens wear. And because there are so many options, it is important to discuss the matter fully with an eyecare professional, who will consider your overall vision problems, the health of your eyes, and your specific visual needs and motivations. So don't forget to ask your doctor about contact lenses; they may fit your lifestyle just right!
