Zenni: The Best Optical Shop
When you buy any kind of eyeglasses you need to know your PD. What is PD? Well, it the distance between the pupils of your eyes that is measured in mm. You can shop for your eyeglasses even your just staying at home through internet. Try to visit Zenni: the #1 online eyeglasses store. Make sure you get No PD for you from Opticians. Some may tell that they will not going to tell your measurement unless you buy the product to them. So I decided to measure it myself with proper guidelines.
