A faucet mounted eyewash unit for installation onto the discharge end of a standard faucet spout. The eyewash unit in a normal faucet mode position permits uninterrupted water flow through the faucet spout. In an eyewash mode, a portion of the eyewash unit is rotated quickly and easily to orient a pair of eyewash discharge ports in upwardly open positions, and to couple these eyewash discharge ports to the water flow for upward trajection of a pair of eyewash flushing streams. The eyewash unit further includes a thermostat for preventing hot water flow above a selected temperature level to the eyewash discharge ports.
