Causes of dark spots under the eyes: -

 - Inadequate sleep, extreme fatigue or the habit of staying awake for more than a few hours from normal sleep time can cause dark spots under your eyes.Inadequate sleep makes your skin dull and pale,making black tissue and blood vessels under your skin visible.

 - Excessive strain on the eyes if you look at the television or computer screen for a long time.This extra stress can cause the blood vessels around your eyes to become larger.As a result, the skin around your eyes becomes black.

 - Dehydration is one of the causes of dark circles under the eyes.When there is not enough water supply in the body, the skin under the eyes starts to become dull and the eyes go inwards.

 - Excessive sun exposure creates an extra amount of melanin in your body.It is a pigment, which makes our skin colourful.  Excessive sun exposure increases the pigmentation around the eyes.Which looks like black spots on the underside of the eyes.

 - Genetic reasons also often cause black spots under the eyes.That is, family history can also be responsible for dark spots under the eyes.If it occurs early in childhood, it is more likely to be an inherited trait.
