Contact lens wear come with some risks and complications as we know, here are some of them;

With contact lens wear, tears are not spread evenly as they should causing the eye surface to dry out easily. It is therefore very important to always use an eye lubricant if you are a contact lens wearer
  • Oxygen Blockage: The eye needs efficient oxygen supply to keep it in normal function and oxygen is diffused into the cornea, contact lenses are placed directly on the cornea this could reduce or completely block sufficient oxygen from getting to the eyes.
  • Abrasion on the cornea: if the contact lens isn’t your fit, it could scratch the cornea causing a cornea abrasion.
  • Red eyes and conjunctivitis: long hours of contact lens creates an opportunity for bacteria and virus to breed on the conjunctiva causing an infection.

YOU SHOULDN’T CONSIDER WEARING CONTACT LENSES IF:

  • You already have Dry Eyes Syndrome
  • You are always exposed to a harsh environment.
  • You already have a corneal infection.
