Do you trust the safety of at-home red light therapy devices purchased online?
Optometrists have expressed significant concerns regarding the safety and efficacy of at-home red light therapy masks. Clinical experts note that there is a current lack of data supporting these non-regulated products.
Why it matters
The surge in online availability for home-use light therapy devices has left many consumers without guidance on potential eye risks. Specialists emphasize that device safety is critically dependent on specific wavelengths, intensity, and proper light placement.
Professional-grade devices like the iLight LLLT Pro, Marco Equinox, LM LLLT, Celluma, and InfinityPro are recommended over untested alternatives. The FDA did authorize its first photobiomodulation treatment for dry age-related macular degeneration in 2024.

Culture Shift
The growing popularity of at-home beauty and health technology often outpaces clinical verification, creating a widening gap between regulated medical equipment and consumer-grade trends. This shift mirrors historical cycles where emerging wellness fads operate without formal oversight.
Consumers should verify that any light therapy device they purchase includes verified eye protection and meets regulated intensity standards. Relying on untested devices may result in unintended optical exposure rather than intended health benefits.
The takeaway
When choosing wellness devices, verify that the product has undergone clinical testing rather than relying on online marketing claims. Always prioritize devices that provide specific, rated safety features to protect your vision during use.
