Contact lenses offer clear vision and convenience, but without proper care, they can increase the risk of corneal infections—a serious eye health concern. In Karachi’s warm and often dusty environment, the risk of contact lens-related corneal infections can be even higher. Understanding how these infections occur and how to prevent them is essential for anyone who wears lenses regularly.

Understanding Corneal Infections

The cornea is the clear, dome-shaped surface at the front of the eye. When bacteria, fungi, or parasites contaminate contact lenses or lens solutions, they can enter the cornea and cause keratitis, a potentially vision-threatening infection. Improper lens hygiene, extended wear, or sleeping in lenses are common risk factors.

Common Symptoms

Early detection is critical. Watch for symptoms such as:

  • Redness or irritation that doesn’t improve
  • Pain or discomfort in the eye
  • Blurred or decreased vision
  • Sensitivity to light
  • Excessive tearing or discharge

If you notice any of these signs, remove your lenses immediately and consult an eye specialist.

Prevention Tips for Karachi Residents

  • Wash and dry your hands thoroughly before touching lenses.
  • Avoid tap water when cleaning or storing lenses—use only sterile solutions.
  • Follow wearing schedules and never sleep in lenses unless specifically prescribed.
  • Replace lens cases regularly (at least every 3 months) to reduce bacterial buildup.
  • Schedule routine eye exams to detect early signs of infection or inflammation.
  • Be extra cautious during Karachi’s humid or dusty seasons, which can increase the risk of contamination.

Proper hygiene and regular eye check-ups are your best defense against corneal infections.
