What is necessary to place order at Firmoo?

<div class="_help_font_site selected-art-author"> a.   Prescription and PD An eyeglass prescription is necessary for us to process your prescription glasses. If there is no problem with your eyes and you do not need prescription lenses, you could choose non-prescription lenses. PD stands for "Pupillary Distance", which is the distance between your pupils in millimeters. PD is very important for accurately fitting your lenses and achieving clear vision. If there is no PD indicated on your prescription, we recommend checking with your eye doctor. You may also measure PD yourself.
