For people with vision problems, contact lens presents an effective and an invisible tool for correcting your visionary problems without affecting your looks. These super thin plastic lenses are placed over the cornea of the eye to correct the vision problems such as nearsightedness, farsightedness or astigmatism. These days you can wear your favorite lenses even if you have presbyopia and need bifocals.

• The contact lenses can be classified into two categories –
• The soft and
• The rigid gas permeable

Many soft lenses are disposable and can be thrown away after a short period of use. Having a fresh pair of lenses means reduced chances of infection, less cleaning and more comfort. Many of them are also equipped to provide UV protection. The most recent types to hit the shelves are the Daily disposables and the Silicon Extended wear Disposables. Then there are the Colored contacts which are the hip and fun to wear. There are four different types of such colored soft contact lenses:

• Visibility tint
• Enhancement tint
• Color tint
• Light filtering tint

One should not share their colored lenses with anyone.

The rigid gas permeable lenses are more rigid than the soft lenses and are hence more durable. They are made of silicon polymers and allow circulation of oxygen to the cornea of the eye. To achieve optimum comfort they should be worn on a daily basis in order to get used to them.

Both rigid gas permeable and soft contacts are available as extended wear options. It is important to wear these lenses as per the directions and get routine check ups with your doctor.
