From looking at the website, I learned why they can price their eyeglasses so low. When you manufacture your own frames and sell them direct to the customer, you can set your own price and cut out the middleman. Besides no middlemen there is virtually no advertising budget which is normally a company’s biggest expense. Zenni also has a lot of new frames in stock for men, women and kids.
Don’t just take my word for it, check out the Zenni website and send them your Rx prescription which is checked by their own certified technicians for prescription accuracy and optical clarity before shipment. Keep in mind that all orders are custom produced and unique to you and your vision needs.
