Ocusweep test menu

Ocusweep tests help you understand how your vision works in everyday situations: how you observe your surroundings, how clear your vision is and how quickly you are able to react to situations e.g. while driving, working, or playing a sport. This is called functional vision.

Visual acuity

Visual acuity is measured by using distance vision, terminal vision and near vision tests.

Visual acuity is the traditional metric for assessing a person’s need for glasses. The test quickly reveals whether you need (new) glasses.

Contrast vision

By measuring contrast vision, we assess how clearly you can see. Can you see lights, shadows and shades of grey very well? Are you able to distinguish objects well in dim lighting, or in bad weather? For example, are you able to distinguish a white plate against the background of a white table?


Visual field

One does not always necessarily notice gaps in one’s own vision. A good and even visual field is essential to your visual abilities in general. Flashes of varying intensities will appear on the surface of the device, in your visual field. This allows us to assess the integrity of your visual field, i.e. whether you can see the flashes at all, whether you can see them at a low intensity, or whether you can only see them at a high intensity.

Reaction time

The reaction time test measures the speed at which your eyes, brain and hands work, and it can give an indication of your brain’s processing speed. Vision-based reaction time affects your safe functioning.



Reaction time field

The reaction time field test determines how well your 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 observations. For example, this test can assess your ability to react while driving in traffic to sudden events at the periphery of your visual field.
