How to use
Night lenses
Wear them for two hours before going to sleep.
Keep them on until you are ready to go to sleep.
Wear them around artificial light at night, including light from smartphones, laptops, TVs and fluorescent lights.
Day lenses
Wear them during long periods of screen use or in brightly lit indoor spaces.
We do not recommend wearing them outdoors, as natural blue light from the sun is beneficial during the day. Artificial lighting has a different light spectrum, which can leave your eyes feeling tired and strained.
The science
When blue and green light between 400 and 550 nanometers reaches your eyes, special light-sensing cells called ipRGCs send a signal to the suprachiasmatic nucleus—the part of your brain that controls your body clock.
This signal stops the release of melatonin and shifts your sleep schedule later. Filtering these wavelengths with red-tinted lenses blocks this disruption, allowing your body to start making melatonin on time instead of up to an hour and a half later.

How’s this better than Night Shift?
LOCKT gives you broader blue-light coverage than Night Shift. Night Shift makes one compatible screen look warmer. LOCKT filters blue light from screens and room lights as it passes through the lenses.
Room lights count, too. Night Shift does nothing to your lamps or ceiling lights. LOCKT filters blue light from those sources, too.
It works beyond your phone. LOCKT also works with light from TVs, monitors and other screens, even when they have no Night Shift setting.
The filter stays with you. Switch screens or move to another room without changing a setting on each device. Just keep your glasses on.

FREQUENTLY ASKED QUESTIONS
Our customer support is available Monday to Friday: 8:00am-8:30pm
Average answer time: 24h
Why are the lenses amber/red?
The amber and red lens are what allow LOCKT to block up to 99% of harmful blue light. Such high percentages of protection cannot be achieved by clear/transparent lens.
Do they actually improve sleep?
Yes. Your screens emit blue light that suppresses melatonin, the hormone your body produces to fall asleep.
By blocking up to 99% of that light, LOCKT lets your body produce melatonin naturally, even while you're still on your screens.
Which lens should I get, amber or red?
Amber (90% blocking): For daytime use under artificial lighting and evening screen work. Reduces eye strain, headaches, and keeps you locked in.
Red (99% blocking): For the final 1-2 hours before bed. Everything the amber does, plus maximum melatonin protection to ensure your sleep and recovery aren't compromised.
If you're picking one to start and are unsure, go with amber. Most of our customers end up getting both.
Do they actually help with eye strain and headaches?
Yes. They reduce glare and visual stress from screens in a way that clear lenses physically can't.
Most people feel their eyes relax within minutes of putting them on. We did, and it's one of the main reasons we kept wearing them.
Will the lenses distort colors?
Yes, both lenses have a noticeable tint.
With amber, everything takes on a warm tone but you can still tell most colors apart, and after 10-15 minutes your eyes adjust.
With red, the distortion is much stronger. Differentiating colors becomes difficult.
If your work requires precise color accuracy (graphic design, photo editing, color grading), we do not recommend the red lens.
I already have blue light glasses and they didn't do anything.
They were almost certainly clear lenses. Clear lenses block 10-30% of blue light at most. LOCKT blocks up to 99%. It's a completely different experience.
What if they don't work for me?
No worries. Every pair is backed by our satisfaction guarantee: 30-day hassle-free returns. Try them risk-free.

For years, I hated being on my computer. All the work I had to do for school was on my computer, and I would stay up late with my eyes burning from the screen. These glasses really changed my life, and now I can't go anywhere near my computer without having these glasses on. Plus, they make me look super cool.
Love these blue light glasses! Definitely noticed a difference in my sleep when wearing them nightly 2 hours before bed.
Would 100% recommend to anyone who uses screens often or not.
Me personally, I’m on the computer and phone all the time so wearing these before bed made a big difference to my sleep and helped me feel calm and relaxed before bed.
Only thing that could be better is the leather case.
The glasses don’t fit too well inside the case and feel like you are shoving them in there when trying to close the case.
Other than that, great blue light glasses!
I use them every day now. Whenever I’m watching a movie, on my laptop, gaming, on my phone, at night, or in the morning. They fit really nicely on my face and look really good. The night-time pair really helps me wind down when I’m about to hit the hay. One downside was that the shipping and delivery took a little over three weeks for both of my pairs. Other than that I’m very much satisfied.
Some glasses change the light. These change the mood.
The daytime pair makes an ordinary afternoon feel a little warmer, like the sun decided to stay a while. The nighttime pair has its own character: bold red lenses, black frames, and the feeling that I’ve stepped into a different scene.
They’re playful, unmistakable, and hard to forget. I bought them to look through. I keep reaching for them because I like how they make the world feel.
I’ve been using LockT blue light glasses for about a week now, and I’ve already noticed a big difference. I spend a lot of time on my computer, and since I started wearing them, I feel like I can focus better and spend more time on my screen without feeling as tired. I’ve also noticed that my sleep has improved, especially when I use them at night.
Really happy with the glasses and definitely glad I got them. Thank you, LockT!
I always had a bad eye problem, especially when looking at bright lights while working,on my phone, or even playing video games. These glasses are absolutely changed that for me and I would recommend to everybody that is on the exact same page. My sleep has been a lot better and my head doesn’t hurt as much 10 out of 10.
Saw lockt on Instagram and thought it would be just another Instagram gimmick, but after having the lockt for over a month I can feel the difference. From someone who job requires them to be on screens a lot I’m so happy I found this product. I feel more productive and don’t feel my eyes getting nearly as tired with the daytime lockts. The nighttime lockts are just as good for winding down for the night while I’m finishing up emails and typing task for the next day. I can truly say it was a great purchase and I am happy with the product!
I can't rave enough about these glasses. I'm behind a desk for 9+ hours a day. They feel great, and I can tell they reduce the stress on my eyes. I don't have headaches as much at the end of the day!
I love them, they genuinely saved my eyes I am in from of 4 monitors everyday for 12-16 hours at any given point they don’t leave my face.
It took me a day to get used to them but I truly love them
I love these blue light glasses. I have problems falling asleep and work on a computer all day. Super comfortable and I’ve had an easier time falling asleep. Not to mention my eyes aren’t as sore and itchy
The LOCKT Nighttime Redlight Glasses have become one of the simplest and most effective parts of my evening routine. I spend a lot of time around screens and indoor lighting, so putting these on as I wind down helps me be much more intentional about reducing bright light exposure at night.
They are comfortable, feel durable and well designed, and the red lenses make it easy to tell that I have shifted into “evening mode.” I especially like that they are practical enough to wear while reading, watching TV, or finishing up a few things on my phone before bed.
If you want an easy, high-quality tool to support a more consistent nighttime routine and create better separation between your workday and sleep, I would highly recommend the LOCKT Nighttime Redlight Glasses.
Absolute game-changer. The daytime lenses keep my eyes fresh through long hospital shifts and charting, while the nighttime pair makes winding down at home seamless. Essential for surviving heavy screen time.
I really love my LockT blue light blockers I got the both the Nighttime and Dayttime lenses and they took me a day or two to get used to but now when I work at night it helps me relax and go to sleep promptly after!
Absolutely love this travel case. The leather feels premium, the quality is excellent, and it’s the perfect size for keeping everything organized while traveling. Looks even better in person and feels like something that will last for years. Highly recommend!
Perfect pair of glasses for work, gaming, and really anything screen related. Really help my eyes when it gets closer to sleeping so my eyes don’t get strained. Been using them daily and will continue to do so!
At first my only concern was the the fitment but the benefit outweighs the con by a mile. These have helped so much with headaches and heavy eyes. Insane quality, overall rating 8.9/10
These glasses are AMAZING! They’ve helped me with my eyes so much in so little time I’ve had them. My eyes don’t hurt or itch when I’m on my computer for hours anymore. They don’t even hurt when I’m in the daylight anymore! Amazing 100% recommend
I've only had them for a little bit but I feel like I noticed a difference immediately. As someone who has never tried blue light glasses I was shocked at the difference in the lighting. I work during the day and study at night so having both the day and night glasses has been amazing.
The “orange lenses” is absolutely amazing for daytime. I have sensitive eyes so driving with them is a blessing. I use the red lenses to do computer work at night. Works great as well. Both are amazing and I utilize them more than I thought I would!
I will preach to everyone forever that these glasses are the best investment for not only your eye health but for your quality of sleep. I wear these daily after a certain hour in the day since I stare at a screen so much and my sleep was instantly deeper and better. The second I put them on I can feel all the muscles in and around my eyes relax. I'll never go back.
My order arrived today! I tried them on and I absolutely love them. I love how sturdy and hard the plastic feels and they look very stylish. I can notice the difference when looking at screens!
