Yes — the prescription must be the same for the second pair as for the first (and for the same person). It then depends on your first‑pair lens type:
- Single‑vision: the second pair must have the same prescription and the same type (distance or reading) as the first pair.
- Progressive: the second pair can be progressive or single‑vision (distance or reading), as long as it follows the same original prescription (same values and addition).
