A wearable optical system capable of displaying dynamic information and images includes a carrier, an information box and a transparent body. The information box is mounted on the carrier and has a wireless sensing unit, a microprocessor and a display unit mounted therein. The transparent body is mounted on the information box and located within a sight range of the wearer, and has a partially-transmitting coated lens mounted on a surface thereof and located on an optical path of the display unit for forming a virtual image on the wearer's retina. A first convex lens is mounted between the partially-transmitting coated lens and the wearer's eyes for adjusting a position of the virtual image formed inside the wearer's eyes.
