Do you often feel eye strain while working and have trouble falling asleep when you spend time at your computer or smartphone in the evening? We are constantly exposed to blue light emitted by smartphones, tablets, laptops, TVs and LED lighting. Its impact on our health and quality of life is very large.
Long-term exposure to blue light, especially in the evening, is a real threat to our circadian rhythm, melatonin production and, consequently, sleep quality, concentration and eye health. In this article, you’ll learn how blue light blocking glasses can help you sleep better and reduce computer-related eye discomfort.
What is blue light?
Blue light is the part of the visible light spectrum with a short wavelength and high energy (400-500 nanometers). In nature, its source is the sun, and during the day it is necessary to regulate our circadian rhythm. It stimulates us, increases alertness and concentration.
The problem arises when blue light sources become artificial and accompany us around the clock. The screens of electronic devices emit them and our brain “thinks” that it is daytime – even at night. This leads to disruptions to the natural circadian rhythm and has negative consequences for our health.
Blue light and sleep.
Melatonin – a hormone secreted by the pineal gland, called the “sleep hormone” – plays a key role in regulating sleep. Its production is directly inhibited by blue light. Evening exposure to them blocks the secretion of melatonin, which leads to:
- Trouble falling asleep.
- Shallower, less restorative sleep.
- Difficulty getting up in the morning.
- Dysregulation of the rhythm of day and night, which can result in chronic fatigue.
Blue light – the effect on your eyesight.
Looking at screens for a long time has a direct, negative effect on our eyes. Symptoms include:
- Eye strain (digital eye strain): burning, dryness, discomfort.
- Dry and irritated eyes due to less frequent blinking.
- Headaches accompanying eye strain.
- Blurred vision and hypersensitivity to light.
Research suggests that excessive exposure to high-energy blue light can be harmful to the retina of the eye, especially the macula. Some researchers point to a potential link with the development of macular degeneration (AMD). Prevention is key.
How do blue light blocking glasses work?
Such glasses limit the amount of blue light reaching your eyes. Their lenses have a special filter. Thanks to this, they support a healthy circadian rhythm and significantly reduce eye strain.
This is a simple and effective solution. Just put them on while using electronic devices or in the evening.
Two types of glasses – choose the perfect one for you.
Most often, you can find two main types of glasses, adapted to different needs and times of the day:
1. Dayglasses
The lenses are slightly yellow in color. They block some of the blue light. Thanks to this, you can use them during the day and protect your eyes from symptoms such as fatigue, dryness or stinging.
NoBlue glasses block 40% of blue light – the optimal amount to effectively protect your eyes.
In fact, they can be used at any time of the day, including in the evening. They are perfect for long-term work at the computer, studying, browsing content on a smartphone/tablet, playing games or watching TV. Ideal for people who spend many hours in front of a screen in the office or at home.
They reduce eye strain, dryness, burning and headaches. They help you maintain better concentration and productivity.
Who do we recommend for?
- Office workers, programmers.
- Pupils and students using laptops and tablets.
- People exposed to artificial LED light.
- Gamers who want to minimize eye strain.
2. Evening glasses
The lenses have a much stronger filter with an orange tint. They block the entire spectrum of blue light that could interfere with melatonin production.
Our evening glasses block 100% of blue light. This is maximum protection and help you achieve better sleep quality.
These glasses are made to be worn after dark, especially 2-3 hours before bedtime. Irreplaceable if you have to use screens in the evening, but want to help your body calm down naturally and fall asleep faster.
They support the natural production of melatonin, make it easier to fall asleep, lead to deeper and more restorative sleep, and consequently – to greater energy and better well-being in the morning.
For whom?
- People using electronic devices in the evening.
- People who have difficulty falling asleep, insomnia, or shallow sleep.
- Those who want to support their natural circadian rhythm and provide a deeper, more restorative night.
- People traveling with a change of time zones (jet lag).
What do you gain by wearing glasses with a blue light filter?
Using such glasses is an investment in your health and comfort. The benefits are multidimensional:
- Better, deeper and more restorative sleep: a key benefit, especially for evening glasses. Improving the quality of sleep translates into better well-being, greater energy and mental performance.
- Less tired, dry and irritated eyes: dayglasses significantly reduce the symptoms of digital eye strain.
- Fewer headaches and more comfort at work: Reducing the strain on the eyes often eliminates headaches.
- Better concentration and efficiency during the day: Less tired eyes and a relaxed mind allow you to work longer and more efficiently.
- Eye health prevention for the future: Protecting the retina and macular can help prevent serious conditions.
- Improved mood and overall well-being: good sleep and no chronic fatigue have a direct impact on mood.
Many people notice an improvement after just a few days of regular wear, especially in the evening.
Are our glasses for you?
Answer the following questions:
- Do you spend many hours a day in front of a computer, tablet, smartphone or TV?

- Do you have difficulty falling asleep, wake up at night or feel sleep-deprived?
- Do your eyes often burn, water, dry or irritated after working with electronics?
- Do you often experience a headache after a long time in front of a screen?
- Do you want to act preventively and consciously take care of your eyesight and health?
- Do you want to improve your concentration and productivity?
If the answer to most is yes, then this is probably the solution for you. It’s a simple change that can bring huge improvement.
Frequently Asked Questions (FAQ)
1. Can I wear blue light blocking glasses during the day?
Yes, definitely! The daytime models are designed for daily work and entertainment in front of screens, reducing eye strain and protecting the retina without disrupting the natural circadian rhythm.
2. Can I wear them over contact lenses?
There is no obstacle to using contact lenses and blue light blocking glasses at the same time.
3. Blue light blocking glasses for kids?
Yes, it is even advisable for younger people to use such glasses. Children’s eyes are still in the development phase and more sensitive. It is important to choose glasses dedicated to children, especially in the evening, so as not to interfere with melatonin production and ensure healthy sleep.
4. Are all blue light blocking glasses the same?
Absolutely not. They differ in filter efficiency, lens quality, frame material, and price. It is important to choose products from reputable manufacturers, with a clearly defined percentage of blue light blocking and certifications. Pay attention to whether they are intended for day or evening use.
NoBlue glasses are tested in a Polish specialist laboratory. We have full test results that confirm their effectiveness.
Summary
Blue light is an inseparable element of our everyday life. Evening, excessive exposure to its artificial sources can disrupt sleep, negatively affect concentration, mood and, in the long term, eye health.
