The refraction test, also know as eye text, is performed with the objective of determining if you have a refractive error, and need contact lenses or glasses.
The test is simply done by asking the patient to sit in a chair that has a special device and focus on a chart situated at 6 meters away. The patient will then look through different sets of lenses. The ocularist will ask him at each time whether the chart looks blurry or clear.
In some cases, abnormal results may occur. The causes of such results are many, including astigmatism (curved cornea resulting in blurred vision), hyperopia (farsightedness), myopia (nearsightedness), presbyopia (inability to focus on near objects). These are some of the cases when we recommend the patient to wear contact lenses and/or glasses.
