Keep your eyes peeled is an idiomatic way to say “to remain alert, to watch carefully, to be on the lookout.” The expression relies on the meaning of the word peel, a Latin derived term meaning “remove or strip,” as in removing an outer covering.
According to the Oxford English Dictionary (OED), the idiom began turning up in print in the mid-1800s, with the first known use dating to an 1844 issue of Atlas magazine: “The Whigs of Hampden must keep their eyes ‘peeled’, or they’ll lose that banner.”
Usage examples:
"Keep your eyes peeled for Polly and Maisie" (watching for people).
"Keep your eyes peeled for any bargains" (looking for items).
"Keep your eyes peeled for a blue sign on the left" (looking for directions)

During the recent (and the 2nd in my life) eye exam, the caring optometrist thought my eye might have an issue and referred me to an ophthalmologist. The ophthalmologist said it's natural and not any issue now, but she would like to perform a preventive laser procedure for possible future issues.
Being confused, I went and talked to my family doctor who suggested I trust the ophthalmologist.
Trust is such a heavy word, especially when it comes to medical care. But, after some consideration, I think I will take the advice, so I can keep my eyes clear and peeled.
