Blue light protection for screen time
Blue light is part of our daily lives. It is found in sunlight, as well as in smartphones, computers, tablets, and LED lighting. When it occurs naturally, it helps regulate energy, alertness, and sleep cycles.
However, prolonged exposure to artificial blue light, especially in the evening or during extended periods spent in front of a screen, can contribute to eye strain, visual discomfort, and sleep disturbances.
Blue light treatment helps filter some of this light to provide a more comfortable visual experience. It is available for most lens types and can be added to anti-fatigue lenses, office lenses, and progressive lenses to adapt your vision to your work, studies, and lifestyle.
What is blue light?
Blue light is a visible light with high energy and a short wavelength. The sun is its main natural source, but it is also emitted by digital screens and LED lighting.
Blue light by itself is not bad. It plays an important role in the circadian rhythm, which helps the body know when to stay awake and when to rest.
Why can blue light be a problem?
Prolonged time spent in front of screens can increase exposure to artificial blue light, which can contribute to eye strain, dry eyes, headaches, or temporarily blurred vision.
In the evening, exposure to blue light can also disrupt the production of melatonin, a hormone that contributes to falling asleep and sleep quality.
How does the blue light treatment work?
Blue light treatment is applied to certain types of lenses to filter out some blue light. It is an option offered at no additional cost thanks to our all-inclusive lens pricing, although it is not compatible with all types of lenses.
Who can benefit from blue light protection?
Blue light protection can be beneficial for anyone who spends long hours in front of a computer, phone, or tablet, especially students, office workers, gamers, and regular screen users.

FAQs
Blue light glasses feature a treatment specially designed to filter a portion of the blue-violet light emitted by digital screens, LED lighting, and other everyday light sources.
Although blue light is naturally present in sunlight and plays an important role in our sleep-wake cycle, many people today spend several hours a day in front of screens. Blue light lenses help reduce exposure to certain wavelengths associated with digital devices.
Many users experience greater visual comfort during prolonged use of a computer, tablet, or smartphone.
Blue light protection can be added to most prescription and non-prescription lenses, making it a practical option for people who regularly use screens.
Blue light is part of the visible light spectrum. It is characterized by a shorter wavelength and higher energy than several other visible colors.
It is naturally emitted by the sun, but also by digital screens, smartphones, tablets, computers, televisions, and LED lighting.
However, blue light is not necessarily harmful. Exposure to natural light during the day helps maintain alertness, concentration, and a healthy circadian rhythm.
Concerns about blue light mainly relate to prolonged screen use, especially in the evening, when it can contribute to visual discomfort or disrupt sleep patterns.
To date, research has not shown that daily exposure to blue light from digital screens causes permanent eye damage.
However, prolonged screen use can contribute to symptoms often associated with digital eye strain, including:
- Eye strain
- Visual discomfort
- Dry eyes
- Temporary blurred vision
- Headaches
- Difficulty concentrating
These symptoms are generally linked to the amount of time spent in front of screens rather than blue light alone.
Blue light filtering lenses may help improve visual comfort for some people, especially those who use digital devices for extended periods. Regular eye exams also remain essential for detecting vision problems that may contribute to eye strain.
Blue light plays an important role in regulating the natural wake-sleep cycle.
During the day, it promotes alertness and helps our biological clock function properly. However, exposure to screens in the evening can affect the production of melatonin, the hormone that helps the body prepare for sleep.
For some people, reducing screen time before bedtime or wearing blue light-blocking lenses can make using digital devices in the evening more comfortable.
If you frequently use a smartphone, tablet, or computer at the end of the day, blue light-blocking lenses can be a useful addition to good sleep habits, such as limiting screen exposure before bedtime and maintaining a regular sleep schedule.
Blue light filtering lenses are designed to promote greater visual comfort in a world where screens play an important role in our daily lives.
Some of the benefits people often look for include:
- Greater comfort during prolonged screen use
- Reduced eye strain caused by digital devices
- Less glare from screens and LED lighting
- Greater visual comfort throughout the day
- A practical option for people who work or study on screens
Whether you work at a computer, participate in virtual meetings, or regularly use your smartphone, blue light filtering lenses may be a useful addition to your glasses.
During your eye exam, your Visique optometrist can advise you on whether this option is right for your visual needs and lifestyle.
