39 Dollar Glasses has an extensive selection of glasses and sunglasses. The website is a good choice for first time buyers, since it has an excellent design that allows easy browsing. When looking at glasses, there is a Smartfit section with 12 different faces, 6 male and 6 female, which allows you to see how the frames look on different types of faces.
For $39, you get glasses with polycarbonate lenses, an extremely light and impact-resistant material, also used for bullet-proof glass. You also get 100% UV protection, scratch-resistant coating and a total quality guarantee. The glasses are often delivered the next day.
For Anti-reflective Coating you will however have to pay more. For all orders over $99, the shipping is free. Also, the shop allows you to do the purchase with money on your FSA account.
