Opticians don't want give you PD data.When we realized my son is having an eyesight problem, we immediately brought him to the optical clinic. They measure his eyes and I have no idea what they did. Only later that I realized that they measure the PD but I wonder why they say that
I would have brought an eyeglasses from Zenni: the #1 online eyeglasses store but shipping here in my country will be expensive. They say Opticians keep you away from ZenniOpt. Is it really true? I am not sure why but I have known Zenni as the cheapest optical online shop.
