Q: I see you have different variations of charts – Pelli Robson Full Set (charts 1&2) or individual 3 or individual 4. ETDRS Charts with A, B, & C or Chart 1, 2, & 3. What are the differences between these product variations?

A: These variations are scrambled versions themselves, which quite simply means that the optotypes are in a different sequence from chart to chart. This variation is created to avoid memorization by your patients during repeated testing. Each variation is produced and calibrated equally.
