Soft Contact Lenses

Since its' introduction in the USA in 1971, soft contact lenses have become the most prescribed medical devices for people with eye problems. Today soft contact lenses are commonly prescribed for such problems as nearsightedness, farsightedness and astigmatism. Soft contact lenses are also the preferred material for bifocals, toric, multifocals and for cosmetic effects, such as non-prescription colored contacts or theatrical effect, such as those used in the movies.

If there are soft contact lenses, there must hard contact lenses. What are the differences between these medical devices and what has made the soft lenses more popular?

A majority of soft contacts are made out of hydrophilic (water-loving) plastics that easily soak up liquids. The result is the contacts are soft, and pliant, allowing them to mold more precisely to the eyeballs. The snug fit means that there are lesser chances for is dust, debris and other materials to be trapped between the surfaces of the eye and lenses. The high water content allows oxygen to flow over the eye, which greatly reduces irritation, or corneal swelling. This in turn makes the adjustment period in wearing them shorter. They are also a popular choice for people with a very active lifestyle.

Such is not possible with hard contact lenses which are made of gas permeable materials. Because they don't follow the curve of your eyeballs with precision, they tend to slid out of place easily. This makes them difficult if not impossible to use, when you are playing a sport.

Some do have and don'ts to remember when using soft contacts are:

• Do make sure your hands are always clean before you put on or remove your lenses.
• Do follow the instructions of your cleaning solutions to the letter.
• Do insert your contact lenses before you put your make up on and use water soluble make up.
• Do put on aerosol sprays such as deodorant and hair spray, before you put in your lenses.
• Do not wear your lenses when engaged in any water related activity. For the lenses might absorb the chemicals and cause you to develop an eye infection.
• Do see your eye doctor if you have blurry vision, get red eyes, it's irritated or there is pain.
