A light input-adjustable window shade has a supporting member 1 coupled to a positioning seat 5 and a level fixing device 6. The level fixing device has a housing and a transmission (62, Figure 3) unit mounted in the housing. The transmission unit includes a rotational shaft (6211, Figure 3) extending beyond the housing. A first end 21 of a spool 2 is rotatably mounted to the positioning seat. A second end 22 of the spool is coupled to the rotational shaft of the level fixing device. A first periphery of a shade body 3 is fixed to and coiled around the spool. The shade body is wound around a rod 41 of a weighting unit 4. A second periphery of the shade body is fixed to a coupling portion of the supporting member.
