The invention belongs to the technical field of novel illumination and display as well as medical auxiliary detecting, and particularly relates to a passive-driving portable multi-functional eye chart. The eye chart comprises an ITO substrate, an eye chart, an OLED stacked light emitting device, a rechargeable button cell and an amorphous silicon solar cell, and a circuit is designed to integrate all components in a specially made box. Solar energy is converted into electric energy by non-monocrystalline solar cells, the electric energy is stored in a button-type rechargeable battery and the stacked OLED is driven to emit light, the passive-driving portable multi-functional eye chart can not only be used for visual inspection, but also can be used for eye protection, color blindness is detected, illuminating is conducted, and the passive-driving portable multi-functional eye chart can also be used as a plane mirror under a non-working status. According to the passive-driving portable multi-functional eye chart, the electric energy stored in the button-type cell is generated by absorbing sunlight through the non-monocrystalline silicon solar cell, controlling is conducted through a circuit switch, so that ideal modes of 'ready to use' and 'self-sufficiency' are realized.
