Eye Examination

Eye Examination

The eye is a complicated organ and the most valued of our human senses. We only get one set so it pays to look after them.

Regular eye examinations are recommended, normally every 2 years. A routine examination takes 30 to 45
minutes and longer if additional specialty tests are required.

There are 4 parts to a comprehensive eye examination;

Part one. We talk to you about your eye sight problem, taking into account past history and general health.

Part two. Refraction. We first take an infra red scan with the auto-refractor, transfer these results to the phoroptor where we assess your vision, and eye muscle control. We may further refine your result with trial lenses.

More common focusing problems

Myopia – an eye that is larger or longer than normal causing distance blur.

Hypermetropia – an eye that is smaller or shorter than normal causing near vision blur.

Astigmatism – an eye that has an oval front surface, and can affect both far and near vision.

Eye muscle coordination – eyes that do not work together and can cause double vision.

Part three. Health assessment. We use a variety of instruments to check both the outsideand the inside of the eye. See specialty tests. Many sight threatening conditions can be treated if detected early enough.

Opthalmoscopy

Part four. Finally we will discuss with you all our findings and the health of your eyes, and offer unbiased advice on what is the most appropriate course of action.

Common sight threatening conditions

Cataracts – Clouding of the lens inside the eye impairing your vision. Generally age-related, but can result from an eye injury. Cataracts are the leading cause of vision loss.

Age-Related Macular degeneration – Ageing can cause damage to the delicate central zone of the retina at the back of the eye, causing a loss of central vision for fine details, eventually we may not be able to read, drive a car, or recognise faces. AMD is the leading cause of blindness in older people.

Glaucoma – A drainage problem, creating too much “pressure” inside the eye, leads to a loss of side vision, that ultimately leads to blindness if untreated. It is important to detect glaucoma in the early stages, because any vision loss cannot be returned. 10% of people over 70 will have glaucoma.

Diabetes – Diabetics are at risk of losing vision as a result of retinal bleeding and other complications. There are over 200,000 diabetics in NZ.

Computer Vision Syndrome

Today’s computer generation can spend significant amounts of time in front of a computer screen. It is estimated that 80% of the workforce suffers from some form of CVS.

Symptoms:

  • Headaches
  • Difficulty focusing near or far
  • Tired achy eyes
  • Burning, dry eyes
  • Neck and shoulder pain

If your suffer from any of these symptoms you may need corrective lenses.
