Does your dad have a suit and tie sort of job, or is he more blue collar? Suit and tie dads will love knock off Gucci sunglasses with sensible thin frames and polarized lenses for their work commute. Blue collar dads will love plastic framed sunglasses that will take them from the factory to after work fishing. Does dad already wear a pair of sunglasses? Consider buying him a great accessory like a hard case or neck cord. Athletic dads will love the convenience of a neck cord, which allows them to remove their sunglasses while still keeping them close by. Does your dad have a sense of humor? Since prices are so low, why not buy him a pair of oversized J Lo style rhinestone sunglasses and wrapping them up as a gift? After your dad has a good laugh, you can give him his actual pair, and then keep the gag pair for yourself or your special lady.
