What Happens During An Eye
Examination?
The Eye Examination
is split into two parts:
1.
Ocular Health Screening
2. Vision Correction |
| |
|
|
1. OCULAR HEALTH
SCREENING
This is done as a routine part of every examination. It checks for
the presence of eye diseases such as glaucoma, cataracts and macular
degeneration.
Depending on age, a combination of the following tests is done: |
| |
|
|
 |
|
Front
of Eye Examination:
The structures of the front of the eye are checked using a microscope
type instrument that magnifies individual tissue and cell layers. |
| |
| |
 |
|
Back
of Eye Examination:
The inside of the eye is checked using a very high powered lens attachment
and the microscope. This is one of the tests for Glaucoma |
| |
|
|
| |
 |
|
Visual
Fields Test:
Checks for abnormal blind spots, which can indicate the presence of
nerve damage. |
| |
|
|
| |
 |
|
Eye
Pressure Measurement:
Checks the fluid pressure inside the eye. Abnormal readings can be
indicative of Glaucoma. |
| |
|
|
| |
|
|
2. VISION
CORRECTION
This is done routinely on everyone.
The aim is to optimise clarity and visual comfort.
A combination of tests is carried out, depending on symptoms. |
| |
|
|
 |
|
Retinoscopy:
The
eyes refractive status is measured by assessment of a reflex that
is projected of the retina |
| |
|
|
 |
|
Calculation of
Spectacle Prescription:
Different lenses are placed in position
until the letters on the test chart are as sharp as possible |
| |
|
|
 |
|
Binocular
Vision Assessment:
Vision correction involves not just rectifying obvious focusing errors
such as long, short sight or astigmatism, but also correcting other
imbalances in the visual system, such as muscle weakness or poor eye
coordination. The latter are also frequent causes of discomfort and
eyestrain, but are often overlooked. |
