Balanced Filtering
Your biorhythm is your internal clock, regulating energy, alertness, and sleep. Spending a lot of time indoors and looking at screens exposes your eyes to an unnatural peak of blue light. AlinaSleep daytime glasses reduce this peak, supporting more natural light signals without compromising clear vision, comfort, or style.

Eye fatigue support
My workdays are so much more comfortable
I spend at least eight hours a day in front of two screens. Around 3 p.m., my eyes always felt tired and dry. These glasses soften the harsh light without changing the colors too much. I was worried everything would look yellow, but the lenses remain remarkably clear. The glasses have become such a natural part of my workspace that I notice the difference immediately when I forget to wear them.
Perfect for working from home
Working from home means looking at screens all day: from my laptop in the morning to answering emails on my phone in the evening. These glasses make everything a little softer without making the world look yellow. They’re lightweight, comfortable, and stylish enough to wear throughout my workday without giving it a second thought.
No color distortion
I'm a graphic designer, so accurate color reproduction is incredibly important for my work. I was hesitant about blue-light glasses because I expected everything to look yellow through them. These glasses pleasantly surprised me. The colors remain surprisingly natural, while my eyes feel much more comfortable after long editing sessions. Exactly what I was looking for.
Ideal for programmers
I work as a programmer, so I look at screens for ten hours or more on most days. I didn’t expect a huge difference right away, but after a few weeks I noticed that my eyes felt much less tired at the end of the day. The glasses are so comfortable that I wear them from my first cup of coffee until I close my laptop in the evening. I also received a free e-book and applied some of the tips from it, which has helped me feel even better during the day.
From curiosity to confidence
Wear yellow lenses during the day (for example, behind your screen or under artificial light) to reduce fatigue and overstimulation. Red lenses are intended for the evening, when it’s dark outside or approximately two hours before bedtime. They block all disruptive light frequencies that can interfere with your biological clock, helping you drift off to dreamland.

The light-yellow lenses filter 35% of the blue-light spectrum between 380 and 455 nm. This softens the brightness of screens and artificial light, while allowing enough light through during the day to support alertness and a stable circadian rhythm.
Wear the glasses during the day while working, studying, gaming, or spending extended periods looking at a screen. For the evening, we recommend our red Alina Night Glasses.
During the day, your body needs blue light as a signal to stay awake and alert. That’s why the Day Glasses offer a considered balance between filtering and sufficient light transmission.
Yes, most customers quickly find a suitable size. Check our size chart for the right fit. And good to know: women say that the glasses also “sit well in their hair.”
Many of our products are based on scientifically researched principles related to sleep, light, breathing, and recovery. Think of the effect of blue light on melatonin, or the benefits of nasal breathing for deep sleep.In practice, our customers often notice a difference after just the first night—physically and mentally. Some products require a short adjustment period, but the effects are quickly noticeable when you use them consistently.Want to track your progress accurately? Then we recommend using a sleep tracker or another measurement device. This way, you can also see the impact in numbers, alongside what your body and mind are already feeling.
Dark yellow lenses can filter out too much light during the day, which may make you feel less alert and give everything a yellow tint. The Alina Day Glasses offer the perfect balance: enough filtering for comfortable screen use, while keeping the image natural and allowing enough light through for focus, energy, and your circadian rhythm.
Yes, especially for children who spend a lot of time behind a computer, tablet, or phone during the day. Size S is suitable for children.
The Day Glasses were developed for screen work and can be claimed as computer glasses with many employers. Reimbursement depends on your employer’s policy. Visit our reimbursement page for more information.
We can indicate on the invoice that they are computer glasses.
