If you are looking for a new pair of prescription glasses you might want to check out zennioptical.com. They have a wide range of frames includes tinted sunglasses, bifocal and progressive frames and even goggles. Personally I quite liked their range of rimless frames. Most of their frames come in a choice of colours and once you have selected one you can also select the lens size and shape, add an anti reflection coating, choose whether you want a lens tint and also add a clip on sunshade. You also need to enter your prescription. They currently ship within the US at a cost of $4.95 per order and most orders are received within two weeks of ordering.
