Light Scatter test

Light Scatter test was designed to measure both the amount and the distribution of scattered light in the eye. Poor spatial vision is often caused by an increased light scatter; therefore, it is important to know how much light is scattered by the optics of the eye. Large amounts of scattered light also cause 'disability glare' which is characterised by visual discomfort and the failure to see fine spatial detail in low contrast environments and particularly during night driving.

Spatial vision refers to the ability of the visual system to perceive and process information about the spatial arrangement and location of objects in the environment in terms of their position, size, shape, orientation, and distance relative to each other and to the observer. Spatial vision is crucial for tasks such as depth perception, object recognition, and spatial navigation, it enables us to perceive the three-dimensional structure of the world around us.

The test is totally non-invasive and easy to use. It is particularly useful to those employed in the transport industry and having to drive at night and following eye surgery.
