This makes the dots of light appear slightly elongated with dark tails.
In a technique known as blue field entoptoscopy, the effect is used to estimate the blood flow in the retinal capillaries.The patient is alternatingly shown blue light and a computer generated picture of moving dots; by adjusting the speed and density of these dots, the patient tries to match the computer generated picture to the perceived entoptic dots.
The dots are usually black/gray on a white background and gray/white on a black background; however, they can also be transparent, white flashing, or colored.
