The world’s biggest retailer says it wants to make kiddy eyewear more affordable. On Thursday, Wal-Mart (Stock Quote: WMT) launched a program to bring down prices for its children's eyeglasses, frames and contact lenses, all with the promise of saving customers $400 million during the next three years.

Wal-Mart says it’s offering frames and lenses for kids for a combined total of $39, which is $20 cheaper than before. There’s also a one-year replacement guarantee if the glasses are damaged.  As for lenses, the retailer is teaming up with 1-800-Contacts to offer a 12% to 50% discount on a year’s stock of lenses for kids.

My parents could have really used this back in the 90s, when I started donning my $200 geek-chic frames, which coincidentally fell out my pocket and got run over by a car in a Sam’s Club (a division of Wal-Mart) parking lot a year later.  Eerie.
