OCUSWEEP TEST MENU

 

OCUSWEEP tests help your customers understand how their vision functions in daily situations: how they observe their surroundings, how clear their sight is and how quickly they are able to react to fast-paced and/or sudden situations e.g. while driving, working, or participating in sports. This is called functional vision. These tests are important since negative changes in functional vision can also indicate a latent, but treatable eye disease.

With the help of the OCUSWEEP method, information is obtained about the functioning of the whole visual system – from the ability of the eyes to see to the efficiency of the brains to process visual information – and the accuracy of the eye movements. In other words, a full OCUSWEEP examination will help your customers get a real understanding regarding the state of their visual fitness!

 

 


VISUAL ACUITY

Visual acuity is measured by conducting distance vision, terminal vision and near vision tests. Visual acuity is the traditional metric for assessing a person’s need for glasses. These tests quickly reveal whether you need (new) glasses.

Visual acuity measurement is used to verify that the narrow path to the posterior part of the eye is clear, and that the small sharp-vision area, or fovea, is functioning properly.


CONTRAST SENSITIVITY

By measuring contrast sensitivity, we assess how clearly people can see. Lights, shadows and colors should stand out clearly for them. Weak contrast vision causes fogginess and weakens their capability to see and recognize objects, especially in poor weather and under dim conditions.

Contrast vision measurement reveals the ability of the structures of the eye to detect differences in brightness. This is necessary e.g. for face recognition and for the ability to see in poor visual conditions. Contrast vision can be compromised by eye diseases, such as cataracts, glaucoma, or diabetes even when the visual acuity may remain good.

 


VISUAL FIELD

Visual field examination is used to measure how the eye, ocular fundus, optic nerve, and the brain perceive different areas of the visual field. An intact visual field is needed for fully functional vision. Defects in the visual field can be caused by diseases of the posterior part of the eye, glaucoma, or a brain tumor. If deficiencies are detected in the visual field, further examinations are always recommended.

These measurements are needed since deficiencies in the visual field are not necessarily noticed in everyday life. The brains tend to start filling in the gaps along the time. A good and even visual field is essential for functionality and well-being in general.


REACTION TIME

Vision-based reaction time serves as an indication of the speed of the eye/brain/muscle coordination. In practice, when one sees a stimulus, a signal will travel from the eyes along an optic nerve to be registered in the brains. Subsequently, a message is sent to another part of the brains that controls the muscles. The brains must then send another signal along the nerves to the muscles, telling them to act in line with the instructions.

This is called vision-based reaction time. If the sensory impressions are processed fast, the functionality is efficient, and vice versa. Prolonged reaction time leads to weakened vision. Vision-based reaction time affects the safe functioning of people, e.g. in traffic.

 

 


REACTION TIME FIELD

The reaction time field test determines how well the entire visual system functions. A good result on the test requires a normal visual field and a good focus and a solid control of eye movements as well as quick processing of the observations. It is an excellent choice when an overview of the functioning of the whole visual system is needed.

This test can assess the ability to react to sudden events at the periphery of the visual field, e.g. while driving. It also provides a unique opportunity for monitoring performance training and rehabilitation for athletes.

Reaction time field measures, in addition to the visual field, the speed of the vision and the reactions to events in different parts of the visual field. The test results are based on agile and precisely controlled eye movements, and accurate reaction to the stimulus.
