Get it right, right away.
Your lens prescription should be as up to date as the style of your frames. If you don’t have a current prescription, get one at any optician near you.
Please make sure your prescription includes the following.
Sphere value of each eye (S, SF, or SPH) and/or
Cylinder value of each eye (C, or CYL)
Axis value (A, As, AXI, AXS, or AXIS)
Pupillary distance of each eye (PD – Divided by two, if only one value is provided)
Additional value (Add – the difference between near- and farsightedness) when you order progressive lenses
If you already have glasses, your optician can copy the prescription from that pair. Or simply visit the next Found store near you and we measure your values.
