Red Light Therapy Goggles Compared: Lens Types and Fit
Published October 2026. Updated October 2026.
Quick answer
Good goggles for a light panel do three things: block the light your device emits, cover your whole eye area with no side gaps, and stay comfortable for the whole session. Compare tint, coverage and fit, ask the seller what wavelengths the lens is made for, and do the fit test below before you rely on them. The FX300 and FX500 include goggles in the box.
What goggles are for
A light panel is a bright light source, and the part of your body most sensitive to bright light is your eyes. That is the whole reason eye protection is part of every device manual. This page is about comparing goggles, not about why you need them. If you want that background, start with our guide to eye protection with a light panel.
One thing to keep straight: closing your eyes is not the same as protecting them. Eyelids reduce light but do not remove it, and a panel at close range is far brighter than most things you look at. Follow your device manual on eye protection, and read this page as general shopping information.
The four things to compare
1. Lens tint and what it is made for
Not every dark lens is made for the light your device emits. Sunglasses are designed for daylight. A tinted lens made for a light therapy device is chosen with that device's wavelengths in mind. Our panels use 660nm red and 850nm near infrared light, and the second of those is invisible, so you cannot judge a lens by how bright the room looks through it.
What to ask a seller: which wavelengths was this lens made for, and is there a written specification? If the answer is vague, count that as a flag. A claim like "blocks all light" with no detail is not a specification.
2. Coverage and side gaps
Light does not only arrive head on. It also comes in around the edges. Goggles with wide wrap around frames, a deep brow and soft side seals leave less room for stray light than flat lenses on thin arms.
3. Fit over glasses
If you wear glasses, you have two choices: goggles designed to sit over them, or goggles that replace them for the session. Over glasses styles are roomier and can press on the nose bridge. Check that the frame does not push your glasses into your cheeks.
4. Comfort and weight
A session is a few minutes at a time, but a pair that pinches or slides will end up pushed up on your forehead. Look at strap width, nose padding and weight. Comfortable goggles get worn, and worn goggles are the only kind that protect.
Comparison table
| Style | Strength | Watch for |
|---|---|---|
| Wrap around with side shields | Least stray light at the edges | Can feel warm, may fog |
| Flat lens, plain arms | Light and easy to wear | Gaps at the sides and top |
| Over glasses frame | Fits on top of prescription glasses | Bulk, pressure on the nose |
| Strap style | Stays put when you lie down | Strap tightness around the head |
| Small or youth fit | Better coverage on a smaller face | Adult sizes slide and leave gaps |

A simple fit test you can do at home
You do not need lab equipment to catch a bad fit. Do this in a dim room with the device off first, then with it on and your goggles on.
- Put the goggles on and close the strap or arms the way you will wear them.
- Face the unlit panel from your normal distance and then look from side to side, up and down. Note any place where you can see more than a shadow of the room.
- Turn the panel on, keeping your eyes closed behind the goggles, and look for light creeping in at the nose, temples and brow.
- Move your head slowly. A good pair stays put.
- If any gap appears, adjust the strap, try a different size, or choose another pair.
This test checks fit and gaps. It does not measure how well a lens blocks specific wavelengths, which is why the specification question matters.
What the references say
The FDA's page on laser products explains that LEDs are different from laser diodes and fall outside the federal laser performance standard. That is a classification point. It tells you nothing about how comfortable a bright LED is to look at, so it should not be read as a reason to skip eye protection.
A review in Progress in Retinal and Eye Research looked at white LEDs used for home lighting and found that some of the lamps assessed fell into photobiological risk groups 1 or 2. That paper is about household lighting, not light therapy devices, but it is a reasonable reminder that bright LED light is a real topic in eye research. If you have a question about your own eyes, ask an eye care professional.
Goggles that come with a device
The AWA FX300 panel lists goggles in its box, and so does the AWA FX500 panel. Read the manual that comes with yours for how to wear them. If they do not fit you well, contact us through the contact page rather than skipping them.
Common mistakes
- Using sunglasses because they are dark. Daylight sunglasses are not chosen for a light therapy device.
- Buying on price alone and never asking for a lens specification.
- Wearing goggles pushed up on the forehead and pulling them down only for part of the session.
- Skipping the fit test, then discovering gaps at the sides.
- Sharing one adult sized pair with a smaller face.
- Using scratched or cracked goggles because they are "still fine".
- Assuming the invisible near infrared part of the light is harmless because you cannot see it.
Before you use any light device: read the label, follow the device manual, and use eye protection as directed. Speak to a qualified professional before use if you have any medical question, take medications, are pregnant, or have light sensitivity.

Frequently asked questions
Do I need goggles for every session?
Follow your device manual. Most manuals call for eye protection, and we recommend you keep it on throughout.
Can I use sunglasses instead of goggles?
We do not recommend it. Sunglasses are made for daylight, not for the wavelengths a light therapy device emits.
Do goggles work over prescription glasses?
Some designs are made to sit over glasses. Check the fit with the test above and make sure the frame does not press your glasses against your face.
Do the FX300 and FX500 come with goggles?
Yes, both product pages list goggles in the box. Read the manual that comes with your device.
How do I know a lens is right for my device?
Ask the seller which wavelengths the lens is made for and ask for a written specification. If no one can tell you, choose another pair.
