Eyes can develop infections from bacteria, fungi or viruses. Eye infections can occur in different parts of the eye and can affect just one eye or both.

One of the most common eye infections is conjunctivitis, also known as pink eye. You can get more information on conjunctivitis from EyeCare America.

Symptoms of eye infections may include redness, itching, swelling, discharge, pain, or problems with vision. Treatment depends on the cause of the infection and may include compresses, eye drops, creams or antibiotics.

Potential of Infections from Decorative Contact Lenses

Decorative ("cosmetic") contact lenses -- which create "cats' eyes" and other special effects -- are popular with teens and young adults, but they have the potential to damage eyes permanently. Cosmetic contact lenses, which do not correct vision, should be prescribed by an eye care professional to insure the lenses will fit properly and that you will receive essential information on contact use and care.

Improperly dispensed cosmetic contacts can result in pain, inflammation, or vision loss. Although over-the-counter sales of cosmetic lenses have been illegal in the United States since 2005, decorative contacts are still widely available in retail stores and on the Internet. When prescribed and used appropriately, contact lens -- corrective or decorative -- are among the safest of medical devices. But without the proper care, wearing decorative lenses may mean courting disaster.
