Ask for the instructions that apply to the device being used. Red-light products come in different forms, and a general comment about light does not tell you how to position yourself or protect your eyes during a particular session.
Follow the specified protection.
The American Academy of Dermatology advises following device directions and using the recommended eye protection when the directions require it. Do not assume that closing your eyes, wearing ordinary glasses or borrowing unrelated goggles fulfils that instruction.
Before beginning, ask who will explain the setup and how you can stop the session. If the directions are missing or unclear, resolve that before using the device.
Bring your own questions forward.
- What is the exact device and intended use?
- What does its manufacturer say about eye protection and positioning?
- Is the recommended protection available and suitable for this session?
- Which health conditions, medications or sensitivities should I discuss with a clinician first?
- What should I do if the light feels uncomfortable?
You do not need to diagnose your own risk in the reception area. If an eye condition, treatment or medication raises a question, ask the appropriate clinician before proceeding.
Avoid turning brightness into reassurance.
The way a panel looks in a photograph is not an eye-safety assessment. Nor can another person's comfortable experience establish that your setup is correct.
A useful introduction should leave you knowing what to do, what protection to use and how to stop. Keep those practical instructions with the session instead of replacing them with a remembered tip from a different device.
