Extra strength means the prescription is greater than Spherical -8.00 , or +6.00, and /or Cylindrical greater than -2.00, or +2.00.
When Any of the Spherical or Cylindrical values on your single vision eyeglass order has an X next to it it is Extra Strength, has to go to the Custom lab for special processing, costs $9.00 extra (sorry), and can take about five days longer to deliver.
