Blue light protection for everyday screen time
Blue light is part of daily life, from sunlight to smartphones, computers, tablets and LED lighting. When naturally occurring, it helps regulate energy, alertness and sleep patterns.
But too much blue light exposure, especially in the evening or during long hours on digital devices, can contribute to disrupted sleep.
Blue light coating can help filter a portion of this light for your digital experience. Available on virtually any lens type, it can be added to anti-fatigue lenses, office lenses and progressive lenses, making it easy to personalize your vision for work, school and everyday life.
What is blue light?
Blue light is a high-energy visible light with a short wavelength. The sun is our main natural source, but it also comes from everyday digital screens and LED lighting.
Natural blue light is not bad on its own. It helps support our circadian rhythm, which signals when it’s time to be alert and when it’s time to rest.
Why can blue light be an issue?
Extended screen time can mean more exposure to artificial blue light, which may lead to disrupted circadian rhythms.
Blue light exposure in the evening can also interfere with melatonin production, which may make it harder to fall asleep or get restful sleep.
How blue light coating works
Blue light coating is applied to eligible lenses to help filter a portion of blue light. It is an optional lens add-on available at no additional cost through all-in lens pricing, but it cannot be added to every lens type.
Who can benefit from blue light protection?
Blue light protection may be helpful for people who spend long hours on computers, phones or tablets, including students, office workers, gamers and anyone who uses screens regularly throughout the day.

While blue light is naturally present in sunlight and plays an important role in regulating our sleep-wake cycle, many people spend long hours in front of digital devices. Blue light lenses can help reduce exposure to certain wavelengths of blue light associated with screens.
Many wearers report improved visual comfort during extended screen use, especially when working on computers, tablets, or smartphones throughout the day.
Blue light protection can be added to most prescription and non-prescription lenses, making it an easy upgrade for anyone who spends significant time using digital devices.
Blue light is a type of visible light with a shorter wavelength and higher energy than many other colors in the visible spectrum.
It is naturally emitted by the sun and is also produced by digital devices such as smartphones, computers, tablets, televisions, and LED lighting.
Not all blue light is bad. In fact, exposure to natural blue light during the day helps support alertness, mood, and healthy sleep-wake cycles.
The concern for many people comes from prolonged exposure to digital screens, particularly during evening hours, when excessive screen use may contribute to visual discomfort or interfere with normal sleep patterns.
Current research has not established that everyday exposure to blue light from digital devices causes permanent eye damage.
However, spending long periods looking at screens can contribute to symptoms commonly associated with digital eye strain, including:
- Tired eyes
- Eye discomfort
- Dry eyes
- Blurred vision
- Headaches
- Difficulty maintaining focus
These symptoms are often linked to extended screen use rather than blue light alone.
Blue light lenses may help improve visual comfort for some individuals, particularly those who spend many hours each day using digital devices. Regular eye exams also play an important role in identifying vision issues that may contribute to eye strain.
Blue light plays an important role in regulating the body's natural sleep-wake cycle.
Exposure to blue light during the day helps promote alertness and supports healthy circadian rhythms. However, screen use late in the evening may interfere with the production of melatonin, the hormone that helps signal to the body that it is time to sleep.
For some individuals, reducing screen time before bed or using blue light filtering lenses may help support more comfortable evening device use.
If you frequently use smartphones, tablets, or computers at night, blue light lenses may be a useful addition to your overall sleep hygiene routine alongside other healthy habits, such as limiting screen time before bedtime and maintaining a consistent sleep schedule.
Blue light lenses are designed to support visual comfort in today's digital world.
Potential benefits may include:
- Increased comfort during prolonged screen use
- Reduced visual fatigue associated with digital devices
- Less glare from screens and LED lighting
- Improved viewing comfort throughout the workday
- An easy lens enhancement for frequent device users
Whether you work at a computer, attend virtual meetings, study online, or spend time on your phone throughout the day, blue light lenses can be a practical addition to your eyewear.
During your eye exam, your FYidoctors optometrist can help determine whether blue light protection is right for your lifestyle and visual needs.
