The best light therapy glasses in the UK are the Luminette 3, because a 30 minute morning session delivers the same light dose as a 10,000 lux SAD lamp while you get on with your day. If your problem is jet lag or shift work specifically, the Re-Timer Gen2 has the strongest research pedigree of the five we compared, and the AYO is the pick for people who want app-guided sessions in a 32g frame.

In-Depth Reviews
1. Luminette 3 (New Model) - Best Overall
๐ Best Overall ยท ยฃ169.99 (was ยฃ199) ยท 4.3/5 from 1,500+ ratings
The Luminette 3 is the pair we'd buy with our own money, because it does the one thing a light therapy device must do, deliver a genuine dose, without chaining you to a desk. The headline spec is the dose: a 30 minute session delivers light equivalent to a 10,000 lux box, which is the standard the NHS describes as the norm for SAD treatment.
It runs at three intensities (500, 1000 and 1500 lux at the eye), uses blue-enriched white light at 468nm, and charges over USB-C, which matters more than it sounds like because everything else in your life charges over USB-C too.
The new model adds the app with light schedules, so you can set a session the way you'd set an alarm, and the frame is light enough to wear while making breakfast, reading or working at a screen. A 2024 study protocol in Frontiers in Endocrinology uses Luminette glasses at exactly this dose to study light therapy's effect on sleep and circadian rhythm, which tells you the device is taken seriously in sleep research.
It's the most expensive pair here at ยฃ169.99, but it's also the most complete.
2. Re-Timer Gen2 - Best for Jet Lag and Shift Work
โ๏ธ Best for Jet Lag ยท VAT-exempt ยท 3.7/5 from 76 ratings
The Re-Timer has the strongest research pedigree of the five. It was developed out of decades of work by sleep psychologists Professor Leon Lack and Dr Helen Wright at Flinders University in Australia, who have studied how light resets the body clock since the late 1980s. The device uses blue-green light rather than white, sits in a solid frame with a strap that keeps the light aimed at your eyes, and is sold in the UK as VAT-exempt because it's classed as a medical device.
This is the pair for people whose problem is timing rather than mood: jet lag, night shifts and early starts. Studies on shift workers show that carefully timed bright light reduces sleepiness and shifts circadian phase, which is exactly the mechanism a morning session with the Re-Timer exploits.
A dose-response study in Scientific Reports found light therapy shifted the body clock and cut sleepiness in shift workers, and a review in Experimental Physiology backs personal light devices as a countermeasure for shift work. The trade-offs: there's no app, and the design reads as sleep clinic rather than fashion.
3. AYO - Best App-Controlled
๐ฑ Best App Control ยท 32g frame
The AYO is the featherweight of the group at 32g, which is about the weight of a golf ball, and you genuinely forget it's on your face after a minute. It's marketed as an alternative daylight lamp and the listing cites clinical testing, with the app as the real point of difference: it guides your sessions, tracks how many you've done, and lets you adjust intensity, which removes the "am I doing this right?" question entirely.
For people who find bright white light glaring first thing in the morning, the AYO is also the gentlest of the five, with a lower output at the eye that reviewers say is easier to live with in a dim room. The flip side is that the lower output means the session needs to be a proper 20 to 30 minutes to count, and the app becomes a subscription-free habit rather than a one-off setting.
If you want the lightest, most guided way into light therapy, this is the pair.
4. Luminette 2 - Best Budget
๐ท Best Budget ยท 2024-updated listing
The Luminette 2 is the previous generation of the same device family, and it does the core job for less money. It delivers the same 10,000 lux equivalent dose in a 30 minute morning session, which means the science doesn't change just because the model number is older. The listing on Amazon UK was updated in 2024, so you're buying a current production unit rather than old stock.
What you give up versus the Luminette 3: the app with light schedules, the higher intensities of the newer model, and some of the fit refinements. If you're the kind of person who will wear the glasses for 30 minutes after breakfast and never open the app, none of that matters, and the Luminette 2 is the sensible buy. It's also the pair I'd recommend to anyone trying light therapy for the first time who isn't sure it will work for them yet.
5. Luminette 3 (Original Blue) - Best Classic Model
๐ต Best Classic Model ยท Same dose as the new model
This is the Luminette 3 in its original blue frame, the version that built the device's reputation before the new model added the app-based schedules. The light dose is identical, the three intensity settings are the same, and it still charges over USB-C. What you're choosing here is the established version of a proven device, which appeals to people who'd rather have the model with the longest track record on Amazon UK than the newest feature set.
The honest framing is that this is the same family as pick one, and you should only buy it if the new model's app features genuinely don't interest you, or if the blue frame is the one you prefer on your face. If you want the complete current device, buy the new model. If you want the classic and a slightly simpler experience, this saves you deciding between them later.
How to Choose Light Therapy Glasses
The dose is the spec that matters, not the lux number on the box. A SAD lamp rated 10,000 lux delivers that brightness at a distance of 25 to 30cm. Glasses sit a few millimetres from your eyes, so they deliver a comparable retinal dose at a much lower lux reading on the spec sheet, typically 500 to 1500 lux at the eye depending on the setting.
What counts is the combination of intensity and time: 30 minutes with a device that aims light at your eyes equals 30 minutes in front of a 10,000 lux box. The NHS guidance on SAD uses 10,000 lux as the benchmark, and the Mayo Clinic's light box guidance says the same: brighter means less time, but the dose is what counts.
Timing does more work than brightness. Bright light in the first hours after waking shifts your circadian rhythm earlier, which is what makes you feel alert in the day and sleepy at a normal time at night. Use the glasses within about an hour of waking for 20 to 30 minutes, and treat evening use as the exception rather than the rule, because late bright light pushes your clock in the wrong direction.
Our circadian rhythm explainer covers the mechanism in plain language, and the sunrise alarm clock guide shows the gentler bedside alternative that does similar work while you're still asleep.
Light colour matters less than you think, but pick what you can tolerate. The Luminette uses blue-enriched white light at 468nm, the Re-Timer uses blue-green, and the AYO uses blue. All three work by hitting the same light receptors in your eye that set the body clock, so the colour is not a quality ranking.
What is a real difference is glare: bright white light aimed at your eyes can feel harsh in a dark room, and some people tolerate the dimmer output of the AYO far better. If you can't stand the light, you won't wear the glasses, and an unworn device delivers a dose of exactly zero.
Weight and fit decide whether you actually use them. The AYO is the lightest at 32g, the Luminette is a step up from that, and the Re-Timer is the most substantial of the three. Try to picture the session: 30 minutes while you make breakfast, read, or sit at a laptop.
A frame that pinches or slides will get abandoned by day three. If you wear prescription glasses, check the fit over your own frames, and if the answer is awkward, a light box or a SAD lamp on your desk is the better route.
Apps are convenience, not a health feature. The Luminette 3 and AYO apps schedule sessions, track usage and adjust intensity, which is genuinely useful for building a habit. None of that changes the light dose, so don't pay extra purely for software you'll ignore. The Re-Timer and Luminette 2 do the job without an app, and for many people that's the more honest purchase.
Safety first: UV-free, UKCA or CE mark, and a GP check if you need one. The NHS says light therapy devices should be UV-free and carry a UKCA or CE mark. Speak to your GP before starting if you have an eye condition or take medicines that increase light sensitivity, and stop if you get headaches or eye strain.
And keep expectations honest: the NHS treatment page for SAD notes that NICE isn't sure how effective light therapy is, so treat these glasses as a tool that helps many people, not a guaranteed cure.
Light Therapy Glasses FAQ
Do light therapy glasses work as well as SAD lamps?
For most people, yes, they work as well as a lamp. The glasses aim the light directly at your eyes from a few centimetres away, so a 30 minute morning session delivers a dose equivalent to a 10,000 lux light box used for the same time. The honest caveat is that NICE says the evidence for light therapy in seasonal affective disorder isn't conclusive, so results vary person to person.
What lux level do light therapy glasses give?
At the eye, between 500 and 1500 lux depending on the setting. That sounds low next to a 10,000 lux box, but the box sits 30cm away while glasses sit millimetres from your eyes, so the dose your retina receives in a 30 minute session is equivalent to the standard the NHS recommends.
When should I wear light therapy glasses?
Morning is the default: 20 to 30 minutes within about an hour of waking. Bright light then shifts your circadian rhythm earlier, which helps you feel alert in the day and sleepy at a sensible time at night. Evening use can delay your body clock and make it harder to fall asleep.
Can light therapy glasses help with jet lag?
Yes, and this is where the wearable format shines. Shift work research shows carefully timed bright light shifts circadian phase, and the Re-Timer was built from Flinders University research into exactly that mechanism. At your destination, use the glasses for 30 minutes in the morning to push your clock toward local time. Our jet lag guide has the full protocol.
Are light therapy glasses safe?
The NHS says devices should be bright enough (10,000 lux is the standard), UV-free and carry a UKCA or CE mark. Check with your GP before using light therapy if you have an eye condition or take medicines that increase light sensitivity, and stop if you get headaches or eye strain.
How long do light therapy glasses take to work?
For seasonal mood symptoms, plan on one to two weeks of consistent morning use before judging the effect. For jet lag, you can feel the timing shift within a few days if you use the glasses at the right time of day. Consistency matters more than session length.
Light therapy glasses vs blue light blocking glasses - what's the difference?
They do opposite jobs at opposite ends of the day. Light therapy glasses add bright light in the morning to shift your body clock earlier. Blue light blocking glasses cut screen light in the evening so melatonin can rise. Some people use both: the Luminette 3 at breakfast, blockers after dinner. Our blue light blocking glasses guide covers the evening half of that routine.
Final Verdict
If you buy one pair of light therapy glasses this year, make it the Luminette 3. The 10,000 lux equivalent dose is the standard the NHS points to, the three intensities and app schedules make it the easiest to use consistently, and USB-C charging means one cable does everything.
- Jet lag or shift work: Re-Timer Gen2 - the Flinders University research pedigree is unmatched.
- Lightest and most guided: AYO - 32g, app-led, gentler light.
- Budget pick: Luminette 2 - the same dose for less money.
- Classic model: Luminette 3 Original Blue - the established version of a proven device.
Remember that glasses are one tool in the light toolkit. Morning bright light works alongside a fixed wake time, sensible screen habits and a dark bedroom, and the NHS treatment guidance is the right place to start if SAD symptoms are affecting you. For more sleep guides, visit SleepReview.
