One of my longtime favorite companies for GREAT deals on amazing glasses is Zenni Optical. Glasses start at just 6.95 (yes, that is frames AND lenses) and shipping is always $4.95, no matter how many pairs you order. Add-ons like anti-glare coating also start at just $4.95.
If you know your prescription, just enter it online. (Note: you will need your pupillary distance. For more on that, visit their site here: goo.gl/gJeytW) Once entered, use coupon code SIGNUP10 for 10% off your order!
The process is easy and the product you receive is excellent. I’ve been wearing my current glasses from them for two years. (And, I paid a grand total of $24.95 for mine!) But, at these prices, you can afford to get several pairs and mix and match them! Check them out at www.ZenniOptical.com.
