(HealthNewsDigest.com) - Contact lenses are more versatile than ever before. Understand the pros and cons of common types of contact lenses — and the ground rules for preventing eye infections.

Soft contact lenses

Soft contact lenses are the most popular type of contact lens both in the United States and worldwide. Soft contact lenses can be used to correct various vision problems, including:

Soft contact lenses are comfortable and easier to adapt to than rigid lenses. Soft contact lenses come in various types, such as:

Hard contact lenses

Rigid, gas-permeable lenses, or hard contact lenses, provide clear, crisp vision for most vision problems. Hard contact lenses might be especially appealing if you've tried soft contact lenses and been unsatisfied with the results or if you have "dry eyes."

Hard contact lenses are often more breathable than are soft contact lenses, which reduces the risk of eye infections. Most hard contact lenses must be removed for cleaning and disinfection at night, but some can be worn for a week or even 30 days.

It might take anywhere from a few days up to a few weeks to adjust to hard contact lenses. However, if your prescription doesn't change and you take care of your hard contact lenses, you can use the same pair of lenses for up to two to three years.

Specialized contact lenses

Depending on your vision needs, you might consider specialized contact lenses, such as:

Getting the right fit

Before getting contact lenses, consult your ophthalmologist or other eye care specialist for a thorough eye exam and fitting. Schedule follow-up exams as recommended by your eye care specialist. You might need a follow-up exam after one week, one month and six months, and then once a year.

Avoiding complications

Wearing contact lenses can cause problems ranging from discomfort to severe infections. To prevent problems with your contact lenses:

Even with proper use and care, dry eyes can be an issue for contact lens wearers. If your eyes are itchy or red, remove your contact lenses and use lubricating eyedrops.

If your vision becomes blurry or you experience eye pain, sensitivity to light, discharge, swelling or other problems, remove your contact lenses and consult your eye care specialist for prompt treatment.
