Calvin Klein glasses manage to surprise and delight in every new season. The recent Calvin Klein glasses collection, at first glance, seems conventional. But when you look closer at the styling, detailing, and craftsmanship, you see that the quality inherent in the Calvin Klein wardrobe is still here in the Calvin Klein glasses collection. The range of glasses still favors metals - full metals, and metal fronts with plastic temples. More and more the designer is adding full plastic glasses frames which offer the sharp lines and rectangularity favored by men and women looking to accentuate the cut of their overall fashion package. Calvin Klein glasses and Calvin Klein sunglasses can all be customized with prescription lenses, just like all of our glasses.
