    Most prescription frames will have your exact measurements engraved 
on the temples (arm pieces) or behind the nose bridge area.
  
  
    On the sample eyeglass frames below, it reads 52 17-150, which translates to an eye size of 52, bridge size of 17 and temple length of 150.
  
  
    Note: Every frame has the same markings on the temples (arm pieces) or behind the bridge (nose area) as shown here:
