rose-colored glasses, to look/see through

To view events and people very positively, seeing only their good points; unmitigated optimism. This term began to be used figuratively by the 1850s. “I was young . . . and I saw everything through rose-coloured spectacles,” wrote Princess Pauline Metternich (Days That Are No More, 1921). A twentieth-century synonym is to see the glass half full, to see the favorable aspect of circumstances, to look on the bright side. The antonym, to see the glass half empty, is also current. “This . . . group . . . looks at a reservoir that is half full and doomfully declares that it’s half empty” (New York Times, 1981).
