Vision is the most important sense needed when driving. Explain five specific areas of vision and how alcohol affects them.
Shalnov [3]

Answer:

Some effects of excessive alcoholic intake on your vision would be:

* Decrease of visual performance. When your visual performance is altered from excessive alcoholic intake, you have a higher possibility of suffering from blurred vision or double vision. The cause of this would be weakening of the eye muscle coordination.

* Slow pupil reactions. Since alcohol affects the speed of when your iris dilates and constricts, it causes an alcoholic driver to have slower reactions to headlights and other important road signals.

* Frequent migraines. Alcohol can also be a trigger for migraines. Before the migraine, the person may experience a visual aura before the headache. They may also see blind spots.

* Increase of redness in the eyes. Since alcohol causes the blood vessels in your eyes to expand, it can make your eyes look red.
