A blue light therapy device belongs to the LED therapy options in this category, rather than being a separate alternative to LED. Product information should identify the wavelength in nanometres and the area the unit is designed to treat. Those details are more useful for comparing models than the colour of the light alone; a device intended for a small area may require a different routine from one covering a larger area.

Light Therapy Devices

The recommended operating distance for near infrared light therapy devices helps determine how much space to allow around the unit. Plan its position around the manufacturer's instructions, rather than fitting it into a spare gap beside furniture. Check that the supplied power adapter for light therapy devices used in a New Zealand home or treatment room accepts 230 V, 50 Hz mains power and has a suitable plug. Access to the socket also matters if the unit needs to be unplugged after use.

Is eye protection needed during a session?

Follow the manufacturer's eye-protection instructions for the specific device, and do not look directly into its light source. Ordinary sunglasses should not be assumed to provide the required protection.

Can light therapy be used while taking medication?

Some medicines can increase sensitivity to light. Ask a pharmacist or the clinician prescribing your medicine before starting treatment, and check the device's contraindications.

How should a device be cleaned between uses?

Switch off and unplug the unit before cleaning it with the method specified by the manufacturer. Avoid spraying liquid directly onto the device or using a cleaning product that could damage its light-emitting surface.
