Shopping online for prescription glasses is another comfort brought to us by e-Commerce.

You only need the mirror and a millimeter ruler if you will be performing it by yourself. Of course, follow the necessary rules to get the accurate measurement.

Nowadays, with the low prices and quality of glasses we could get online, why bother to acquire from the regular store and spend gas for your vehicle where you can save it by doing online? As long as you have the PD and a prescription, you are good to.
