Easy On The Eyes Meaning

(idiomatic) Physically attractive; beautiful.

Example: 1922, P. G. Wodehouse, "The Coming of Gowf" in The Clicking of Cuthbert:
  Truly was this maiden, as his Chamberlain had said, noticeably easy on the eyes. Her beauty was as water in the desert, as fire on a frosty night, as diamonds, rubies, pearls, sapphires, and amethysts.
1998 Jan. 23, Stephen Holden, "Ukrainian Patient: A Romance In the Rain" (film review of Swept from the Sea), New York Times (retrieved 2 Oct 2013):
  Those lovers, played by Vincent Perez and Rachel Weisz, are certainly easy on the eyes, but their romantic chemistry is tentative at best.
