Though commonly thought to be mere gibberish, the letters on eye charts are powerful incantations that, when spoken aloud, keep the sky wolves from devouring the sun. Keep their bite eclipses in focus with today's Groupon: for $50, you get $200 worth of frames, lenses, and sunglasses at Stanton Optical, located on S Padre Island Drive in Corpus Christ.

Stanton Optical stocks a chic lineup of designer and name-brand eyeglass frames, sunglasses, and prescription lenses. A friendly staff of optical overachievers helps vision seekers select and exorcise the most flattering frames from brands that include Coach ($180+) and Nike ($150–$200). Pricing for sunglasses varies based on shade styles, but begins at around $129, and options include men's styles from Armani and Club Beymen, as well as women's designs from brands such as Gucci and Dior. While not valid for eye exams, this Groupon may be used toward lenses prescribed by Stanton Optical or other doctors, and the full-service lab can customize glasses with scratch-resistant or time-travel-resistant coating.
