Cheap Online Prescription Glasses

One of my aquaintances bought a backup pair of prescription glasses online for $15.00. I thought surely that is a joke.  I examined the site and well I think the site has some great ideas and it would make a great pair of backup glasses!  They claim to have better prices than Walmart or Costco with glasses starting at $6.99.  www.zipoptical.com.  The best part of it all- they will let you upload your picture to try on their virtual glasses. That's a great feature! I've always had a problem with choosing the right frame shape for my face... I need glasses to see what I look like.  No longer do I need to depend on someone else to help me with this task and I'll have an idea of which frame shape suites my face.  It is so easy and convenient! They have glasses in different categories: men, women, children, sunglasses,  price range, different types and shapes.   Don't expect the glasses to be high quality- but a cheap second backup pair might be useful. I just might give it a try!
