Important Disclaimer

This database is for educational and informational purposes only. It is not medical advice, diagnosis, treatment guidance, dosage guidance, disease-prevention guidance, or a substitute for consultation with a qualified healthcare professional.

Blue light devices, cosmetic light devices, dermatology-related light systems, screen-exposure claims, circadian rhythm discussions, and consumer wellness products vary widely in intended use, wavelength, irradiance, exposure duration, distance, eye-protection requirements, labeling, and evidence quality.

This reference index does not recommend blue light devices for any disease or condition. It is designed to separate terminology, controlled light-therapy context, cosmetic positioning, device specifications, safety cautions, screen-exposure language, medical-claim boundaries, and citation context.

Blue Light Therapy Reference Fields

The table below uses plain-language terminology, controlled-use context, cosmetic-device context, screen-exposure context, buyer-education notes, and safety categories with visible source/evidence classification and row-level citation notes. The v1.2 CSV and JSON include expanded row-level fields such as source_type, evidence_level, claim_type, medical_disclaimer_required, commercial_relevance, last_reviewed, related_holistix_page, related_product_category, notes, source_name, source_url, and citation_note.

The v1.2 CSV and JSON now use the same row-level source, evidence, and citation framework so both downloadable formats describe the dataset consistently.

Educational terminology / device-category context	Measurement caution	Measurement concept	No	Blue Light in Dermatology	https://www.mdpi.com/2075-1729/11/7/670	Use as general blue visible-light context. Keep screen-exposure language separate from controlled blue-light therapy or consumer device claims.
BLUE-008	Circadian timing	Usage context	Blue light timing can matter because bright light exposure, especially at night, is often discussed in relation to alertness and circadian rhythms.	This dataset does not provide sleep-treatment advice or medical guidance. Users with sleep disorders should consult a qualified professional.	Scientific review	Research context	Usage context	Yes	Blue Light in Dermatology	https://www.mdpi.com/2075-1729/11/7/670	Use for broad blue-light context only. Avoid converting circadian timing discussion into sleep-treatment guidance.
BLUE-009	Wavelength disclosure	Specification field	A useful blue light device listing should disclose wavelength range, LED type, intended use, power or irradiance information when available, safety warnings, and instructions.	If exact wavelength or output data are unavailable, copy should say so instead of implying precision.	Device specification / manufacturer-instruction context	Device specification	Specification field	No	Blue Light in Dermatology	https://www.mdpi.com/2075-1729/11/7/670	Use for blue-light wavelength range and dermatology-context terminology. Supports disclosure of wavelength category and output context.
BLUE-010	Irradiance and distance	Measurement concept	Blue light exposure depends on output intensity, distance from the device, area covered, and exposure time.	Avoid copying clinical or online exposure protocols into consumer use instructions unless they match the device and intended use.	Manufacturer instruction / consumer safety context	Measurement caution	Measurement concept	Yes	Safety and Effectiveness of a New Blue Light Device for the Self-treatment of Mild-to-moderate Acne	https://pmc.ncbi.nlm.nih.gov/articles/PMC3366451/	Use for controlled-device dose and exposure-parameter context. Do not convert study parameters into general consumer recommendations.
BLUE-011	Exposure time	Usage context	Exposure time is a major variable for any light-emitting consumer device.	This dataset does not provide dosage protocols.

Source and Evidence Notes

This index uses cautious educational language because blue light products vary by wavelength, irradiance, exposure duration, distance, intended use, device labeling, safety requirements, and marketing claims. Entries marked as requiring medical disclaimer language should not be interpreted as personalized medical advice, disease guidance, treatment instructions, dosing guidance, or exposure protocols.

Blue light terminology should be separated by context. Screen exposure, circadian timing, dermatology-style devices, cosmetic positioning, and controlled blue light therapy should not be blended as if they are the same category or evidence standard.

Consumers should follow manufacturer instructions, avoid direct LED viewing, use eye protection when instructed, review device specifications carefully, avoid vague disease or cure claims, and consult a qualified healthcare professional if they have photosensitivity, eye conditions, medication concerns, skin conditions, unusual symptoms, or other risk factors.

The v1.2 CSV and JSON add row-level citation fields, including source_name, source_url, and citation_note. These fields are intended to make the dataset more transparent, easier to audit, and more useful for AI/search systems, researchers, journalists, and consumers. Citation notes should not be interpreted as medical claims or product-efficacy guarantees.
