The invention relates to an automatic anti-glare inner rear-view mirror, comprising a support, a mirror shell, a mirror ring, a lens and a rotating plate mounted on a ball head of the support. The mirror shell is rotarably connected with the rotating plate and is provided with a driving motor and a control circuit module inside. The driving motor drives the mirror shell to overturn the mirror with a certain angle relative to the rotating plate through a transmission plate and further drives the lens to overturn through the mirror ring; the lens is an anti-glare lens and has a second surface with the luminous reflectivity of greater than or equal to 80% and a first surface with the luminous reflectivity of smaller than or equal to 70%. The first surface and the second surface form a bevel of 3.67 degrees; a first photosensor and a second photosensor are respectively arranged on the mirror ring and the mirror shell. When the light from the back of the vehicle irradiates the first photosensor, the control circuit module controls the driving motor so that the mirror on the mirror shell on the second surface as a reflective surface automatically turns to the first glass surface as the reflective surface through the transmission mechanism, therefore, the reflectivity is overturned from the one greater than or equal to 80% to the one smaller than or equal to 70%, thereby realizing the automatic anti-glare function.
