Contact lenses: What to know before you buy

What do contacts do?

To help you see better, contact lenses are little, transparent discs that you wear in your eyes. On the tear film that protects your cornea, contacts float.

Contact lenses, like eyeglasses, are used to treat refractive defects that affect vision. When the eye does not properly bend or focus light into the eye, this is known as a refractive error and results in a blurry image.

For those with the following refractive defects, contacts can enhance vision:

  • Myopia (nearsightedness) (nearsightedness)
  • Hyperopia (farsightedness) (farsightedness)
  • Astigmatism (distorted vision) (distorted vision)
  • Presbyopia (changes to near eyesight that generally occurs with ageing) (changes to near vision that normally happen with age)
