Abstract
An apparatus for detecting durability of a wiper blade, may include an optical sensor including a light emitting unit radiating an infrared ray to a windshield glass and a light receiving unit receiving the infrared ray reflected through the windshield glass, wherein the wiper blade may be positioned between the light emitting unit and light receiving unit, and a controller comparing an infrared receiving quantity of the windshield glass transferred from the light receiving unit with a reference receiving quantity to determine an exchange time of the wiper blade.
