Your Eyes Condition

Of all human senses sight is relied upon the most, however a significant proportion of Australian adults cannot see well without glasses or contact lenses.

Fortunately, Perfect Vision Laser Correction offers effective treatment for many of these conditions and, with improved vision, you can enjoy a better quality of life.

Normal eye

The normal eye has a lens that works in conjunction with the cornea (outer surface of the eye) to bend light rays that enter your eye.

This causes the focal point of an image to fall exactly onto the retina (a film-like light-sensitive tissue) at the back of your eye and allows you to see objects clearly.

Signals from the retina are sent through the optic nerve to the brain, where they are interpreted as the images we see.

Refractive Errors

Refractive error exists when light does not focus perfectly onto the retina. Most of us have some degree of refractive error, whether we know it or not.

There are three types of refractive error: myopia, hyperopia, and astigmatism.

  • Myopia or "shortsightedness". If you are myopic, you can see clearly up close, but your distance vision is blurry.
  • Hyperopia or "farsightedness". If you have hyperopia, you may be able to see clearly at all distances, but you have to use extra focusing effort to do so, which can cause eyestrain, headaches, and intermittent blurred vision, especially up close. Hyperopia is often confused with presbyopia (see below), but farsightedness can exist with or without presbyopia.
  • Astigmatism. If you have astigmatism, your vision is blurred or distorted at all distances. Many people who are shortsighted or farsighted also have astigmatism.

Combinations of myopia and astigmatism or hyperopia and astigmatism are common.

Age Conditions

With age, there are other conditions, such as presbyopia and cataracts, that can also impair vision.

  • Presbyopia is the normal, age-related loss of ability to focus on things up close. It affects all of us once we reach our 40s.
  • Cataracts are cloudy areas in the lens of the eye that can cause changes in vision. Symptoms of cataracts include cloudy or fuzzy vision as well as sensitivity to glare.
