Follow the supplied instructions.
Use the care guidance for the exact frame and lenses. A general category photograph cannot tell you which materials, coatings or cleaning methods apply.
Ask about an uncertainty.
If instructions are missing, unclear or an item needs an adjustment, ask the actual supplier or an optical professional before improvising. Do not infer a care method from a different pair.
Keep a useful reference.
Retain the actual model or order reference and the supplied product information. A short description of the issue helps start the conversation without sending medical details.
