Dusk

The twilight visits denotes the ability of the human eye to see in poor lighting conditions, especially at dusk or in slightly illuminated interiors.
In this situation, the eye is challenged by the low light intensity. The pupils have to expand in order to be able to absorb more light.
Twilight vision can be influenced by various factors, such as the quality of the ambient lighting, the contrast perception and the strength of the glasses or contact lenses.
Twilight visits play an important role in many daily activities such as driving or navigation indoors.
