Eye Exam Cocktail Shaker Helps You Celebrate Independence Day, Optometry-Style

According to Time Magazine, the Fourth of July is the seventh booziest American holiday, right behind the likes of Cinco de Mayo, St. Patrick’s Day, and New Year’s Eve. And what better way to say “Happy Birthday America” than to whip up your Independence Day drinks in this cool new Eye Chart Cocktail Shaker?

For just $25, you get both a nifty-looking cocktail shaker, and a built-in sobriety test. As described by the product’s website, if you can still read the “OMG I am so wasted I can’t even read what this says” text, printed eye-exam-style on the shaker’s front, feel free to continue celebrating everything that makes this country great.

Make sure to enter discount code “July4th” at check-out to save 15% off your order, and even receive free shipping if you buy three. I mean, it’s not like Independence Day falls right in the middle of a work week or anything this year. Your liver can handle it.
