Verify the pair you ordered
Match your written order to the supplied lens details. Ask the dispenser to explain any product card, confirm the frame adjustment and demonstrate the intended viewing distances.
Agree on follow-up
Our editorial suggestion is to ask whom to contact for persistent blur, discomfort or fitting problems, and to keep the order record. Do not assume every difficulty is normal adaptation; discuss unresolved symptoms with the practice.
