We purchased a pair of glasses for my husband from Coastal Contacts a few weeks ago when they did the free giveaway. It was so easy! All you need is a prescription from the eye doctor (to get the correct lens strength) and a ruler. You will need to measure the distance between your pupils but the site explains how to measure……..and again very easy. The glasses arrived within a week. He picked the Dakota Smith Defiance in Black which are originally $108.00 just for the frame. I was skeptical about buying glasses online but for the price of FREE, who can beat it? The glasses are very nice quality and my husband loves them. This is definitely a deal that you don’t want to miss out on!!
