Near Infrared Sauna and Blue Light Eye Protection in One Lightweight Design
IR Guardian™ glasses are designed for use around bright near infrared sauna lamps and other light sources when the documented wavelength and optical-density specifications match the application.
The custom polycarbonate design combines front and side coverage, a lightweight over-glasses fit, and listed protection specifications across infrared, ultraviolet, and visible-light ranges.
Infrared energy is produced by sunlight, heaters, fireplaces, industrial equipment, and sauna lamps. Repeated close-range exposure from a bright incandescent lamp is different from ordinary background exposure.
Dark protective lenses reduce visible-light intensity and make it easier to avoid direct viewing of illuminated bulbs.
The listed optical specifications indicate attenuation across a broad infrared range, subject to the actual transmission and optical-density data.
Extended temple coverage helps reduce light entering from the sides compared with flat or clip-on lenses.
The current product information lists the following specifications. Keep each claim tied to the exact lens markings, certificates, optical-density chart, and testing documentation for this model.
| Specification | Listed Information | Responsible Product Wording |
|---|---|---|
| Wavelength range | Approx. 190–1800 nm | Describe as the listed coverage range; do not claim equal or complete blocking at every wavelength without a transmission chart |
| Optical density | OD 4+ | State the wavelength range to which OD 4+ applies when documented |
| Ultraviolet rating | UV400 | Describe as the listed UV rating for this eyewear model |
| Visible-light range | Source lists approx. 380–700 nm protection | Avoid implying uniform attenuation across the entire visible spectrum without test data |
| U.S. standard | ANSI Z87.1 | Publish as verified compliance only when current markings or supporting documentation are available |
| European standard | CE EN166 | Publish as verified compliance only when the current declaration or documentation is available |
| Lens material | Custom polycarbonate | Useful for protective-eyewear construction but not proof of suitability for every laser or IPL source |
If testing was performed in the United States, describe the actual laboratory, report, test method, and result. Do not use "FDA tested" unless the meaning is clear and supported, and do not imply FDA approval or clearance unless it actually exists.
The source describes a broad optical range extending from ultraviolet through visible light and into infrared wavelengths.
Optical density describes how strongly light transmission is reduced at specified wavelengths.
The listed UV400 specification addresses ultraviolet wavelengths up to 400 nm.
The source lists visible-light protection across approximately 380–700 nm.
The temple shape helps reduce lateral light reaching the eyes.
The frame is intended to fit over many prescription eyeglasses without requiring a clip-on attachment.
The universal-style frame accommodates a range of face shapes and many prescription frames. Actual fit depends on temple width, nose shape, lens size, and head movement.
Large gaps around the nose, cheeks, or temples may allow more light to enter. The eyewear should remain stable whenever the user changes position.
Do not move the face or eyes closer to the bulbs than the current Sauna Fix instructions allow.
Eyewear does not prevent overheating, dehydration, skin injury, or other heat-related symptoms.
Laser protection must be selected for the exact wavelength, power, pulse characteristics, and required OD.
| Application | Guidance |
|---|---|
| Sauna Fix incandescent lamps | Use according to the current Sauna Fix lamp and eyewear instructions |
| Other infrared heat lamps | Confirm the actual output range and required optical density before relying on the glasses |
| LED red-light panels | Follow the device manufacturer's eye-safety guidance; brightness and output vary widely |
| IPL equipment | Use only if the exact device, range, power, and required attenuation match the documented eyewear specification |
| Laser systems | Requires a qualified wavelength- and power-specific safety determination |
| Tanning equipment | Use eyewear specifically approved for that equipment rather than choosing by appearance alone |
Remove the glasses from the hot enclosure and allow them to cool before cleaning.
Dust can scratch the lenses when rubbed dry. Rinse or blow away loose particles first.
Use mild soap and water or a cleaner approved for polycarbonate protective lenses.
Do not use paper towels, abrasive pads, bleach, ammonia, or strong solvents.
Dry completely and store in a clean protective case away from hot bulbs and guards.
Deep scratches, cracks, clouding, warping, or uncertain product identification are reasons to remove the eyewear from service.

They are designed as protective eyewear for bright near infrared sauna lamps and other light sources when the documented wavelength and optical-density ratings match the application.
Yes, according to the current Sauna Fix lamp and eyewear instructions. Continue to avoid staring directly into illuminated bulbs.
The wraparound frame is designed to fit over many prescription frames, although actual fit varies.
The source lists approximately 190–1800 nm. This should not be interpreted as equal or complete blocking at every wavelength unless supported by the actual transmission chart.
OD refers to optical density. OD 4 indicates a 10,000-fold reduction in transmission at the wavelengths to which the rating applies. The wavelength range must always be stated with the OD.
Yes. The extended temple design helps reduce light entering from the sides.
The source lists these standards. Present them as verified claims only when the current product markings and supporting documentation are available.
Ordinary sunglasses are not necessarily tested for the same infrared range or optical density. Use protective eyewear with documented specifications matched to the source.
Only after a qualified safety determination confirms that the exact wavelength, power, operating mode, and required OD match the eyewear.
Remove loose debris, use mild soap and water or an approved polycarbonate lens cleaner, and dry with a soft lens cloth.
Replace them if the lenses are deeply scratched, cracked, warped, clouded, or separated from the frame, or if the rating can no longer be confirmed.
Choose IR Guardian™ when you want wraparound coverage, a lightweight over-glasses design, and listed infrared, ultraviolet, visible-light, and optical-density specifications.
“I recently purchased Near Infrared Glasses for use in my Sauna, they fit perfectly and give me peace of mind knowing I am not damaging my eyes while in the Sauna.Thank you.”

“Bought these glasses to wear during IR/NIR light therapy sessions because the light was bothering my eyes and I didn’t want to wear the opaque black goggles that came with the light. These glasses are fantastic at blocking the IR/NIR wavelengths that were formerly causing me eye discomfort. I’m hopeful that due to their safety rating they will guard my eyes against cataracts and other damage from frequent use of my IR/NIR light. Thanks for making a quality product!”

“The glasses fit well and are comfortable. I have not been able to get the information I have asked the company for--to what extent are specific wavelengths blocked by the glasses? I bought the glasses to use with a red light therapy device that emits 850 nm NIR and 660 nm red light and need to know if any, and how much, light in those wavelengths gets through the glasses. Since these glasses are supposed to have been well researched, I assume that the company has this data, but is reluctant to share it.”

Response from Eileen Durfee: In the product description of the glasses, we list all the information you were looking for. It is prominently displayed for everyone to make an intelligent buying decision. The lenses are custom manufactured with a polycarbonate material that covers 100% of IPL nanometers (nm) of light and is rated for UV 400 protection. They meet ANSI Z87.1 and CE EN166, and the OD rating is OD 4+. They also effectively protect against 380-700 nm of blue light. The glasses' temples effectively cover the eyes' side for full protection. Blessings and Health! Eileen Durfee
