the.com/screen time

means The amount of time spent looking at a phone, tablet, TV, or computer screen, usually tracked and reported back to you as a quiet accusation.

from A straightforward compound of 'screen' (from Old French 'escren,' originally meaning a shield against heat or light) and 'time.' The phrase itself is modern, rising with televisions and then exploding with smartphones — it entered everyday worry sometime in the late 20th century, and became a built-in phone feature, and a source of household guilt, in the smartphone era.
