This is a very good point...
It is possible (and we have seen it on this list) that the
prescription is wrong, off, or just not suitable.
If this is the case, then buying your glasses at Zenni had nothing to
do with your dissatisfaction. The dispensary can only promise to
deliver glasses that match the prescription. Once they fulfill that
requirement, their job is done.
