We love Zenni Optical! I wrote for them before and I've mentioned that we are also their customers. You just have to know your prescription for your eyes and you can go ahead and order cheap eyeglasses. Zenni Optical is one of the companies where you realize that you don't have to spend much to get a quality product. Even their shipping is cheap at $4.95 and that's for your entire order, not for each eyeglasses.
If you are feeling retro with colors, you can choose eyeglasses with the color of your choice; even their lenses have various shapes. Of course not all the eyeglasses are priced the same but most of them are cheap, as low as $6.95. You can also get free shipping if you order $50 or more. This is usually my technique when I am buying online is to get free shipping, sometimes I have to wait till I have a wish list of up to the required amount so I can get the shipping for free. I think that's a good deal since you don't have to go to a store, you'll just have your order delivered. With the savings that you will be getting, you can buy more than one eyeglasses so you can express more of your personal style. This holiday season, it really helps when you can save on things that you need.
If you are unsure what to order or if you have questions, they have a live chat that you can click on their website. They are also in Facebook.
