Glasseslit use the high-quality materials, but can offer customers at a high discount because of our high volume, since Glasseslit.com don't have the additional overhead constraints (such as retail rent space, behind-the-counter employees and so on) that your doctor's office or optical must overcome. Since operating this website is much less expensive than a typical retail establishment, Glasseslit is able to pass these savings on to the general public. With no middlemen, no retail-space overhead, Glasseslit.com save our customers on every order!
