CONTACT LENS INFECTIONS

Contact lenses are thin pieces of plastic which cover the cornea. Like spectacles, contact lenses help to correct refractive errors. They can correct myopia (shortsightedness), hyperopia (farsightedness), astigmatism and presbyopia (old-age vision).

There are various types of contact lenses available in the market. Most patients prefer the use of soft contact lenses. These contact lenses may be permanent lenses or disposable lenses. Disposable lenses come in either daily, fortnightly or monthly wear alternatives. The disposable lenses should not be used beyond the recommended period and have to be discarded accordingly.

Hard contact lenses or rigid gas permeable lenses allow better oxygen transmission and may be associated with less allergic response compared to the soft contact lenses, but are much more uncomfortable to wear.

 

Problems & Complications Associated with Contact Lens Wear

Contact lenses are generally safe if the person does not overuse the contact lenses and maintains strict hygiene measures.  However, people should be aware of possible complications of contact lenses, some of which are potentially blinding, particularly if there is a compromise in lens care and hygiene.

Some of the common and serious problems associated with contact lenses are:

  • Droopy Eyelids: Prolonged wearing of contact lenses can also result in drooping of the eyelids with constant stretching of the eyelids. In general, any patient with blurring of vision, redness, tearing or discomfort associated with contact lens wear should remove the contact lens immediately. If the symptoms are significant or persistent, he or she should see an eye specialist who would do a thorough check of the eye and be able treat the condition appropriately.
