Why do doctors recommend blue light glasses?
Some doctors may recommend blue light glasses in the belief that they can help prevent or reduce eye strain and other symptoms associated with prolonged screen use. However, according to multiple studies and reviews, the evidence for their effectiveness is lacking.
Lack of Evidence for Eye Strain Relief
A 2023 review in The New York Times analyzed 17 studies and found that blue light glasses did not prevent or relieve eye strain compared to normal lenses. Previous research has also concluded that these glasses do not prevent tired eyes, irritation, or improve vision after screen use.
Potential Sleep Benefits Unclear
While some studies showed blue light glasses improved sleep scores, others found no effect or even worse sleep quality. There is evidence that blue light can inhibit melatonin production and impact sleep cycles. However, the benefits of wearing blue light glasses specifically for better sleep remain unclear.
Expert Skepticism
Many experts are skeptical that blue light glasses can reduce eye strain or provide meaningful benefits. According to eye doctors, symptoms like eye fatigue are more likely caused by factors like lack of blinking and increased focus on screens rather than blue light exposure itself, which is not inherently harmful in small amounts from devices.
Alternative Recommendations
Rather than relying on blue light glasses with unproven efficacy, experts recommend taking regular breaks, limiting late night screen time before bed, using night mode on devices, and keeping eyes moisturized with artificial tears to reduce digital eye strain. The American Academy of Ophthalmology does not recommend blue light-blocking glasses due to the lack of scientific evidence that blue light is damaging to the eyes.
Common eye problems in kids caused by digital device use
Prolonged Screen Time Effects
Excessive digital device usage, especially smartphones and tablets, can lead to several vision issues in children. One common condition is digital eye strain - characterized by eye discomfort, fatigue, headaches, blurred vision, and difficulty focusing. This occurs due to the intense concentration and prolonged near work required when using devices.
Dry Eye and Eye Irritation
Staring at screens for long periods reduces blink rates, leading to dry, irritated eyes. According to the Children's Hospital of Philadelphia, dry eyes from digital device usage can cause redness, burning sensations, and blurred vision in kids. Positioning screens above eye level exacerbates this issue.
Refractive Errors and Nearsightedness
Multiple studies suggest a link between increased myopia (nearsightedness) development and excessive screen time in children. The American Academy of Ophthalmology warns that more indoor device usage, coupled with less outdoor play, may accelerate myopia progression. This refractive error makes distant objects appear blurred.

Long-term Blue Light Exposure Risks
Prolonged exposure to blue light from digital devices like smartphones, tablets and computers can potentially damage retinal cells over time and increase the risk of age-related macular degeneration in kids. According to a scientific study, blue light with wavelengths between 415-455 nm is most harmful as it directly penetrates the retina and causes photochemical retinal damage.
It induces production of reactive oxygen species in lens epithelial cells, which may lead to the development of cataracts. Blue light also damages the retina by causing morphological changes, impairing blood retinal barrier function, and oxidative stress injury through generation of free radicals.
Disruption of Circadian Rhythm
Exposure to blue light before bedtime disrupts the circadian rhythm and melatonin production, leading to sleep issues in children. As per health experts, poor sleep quality has been linked to various health issues. Some studies found blue light blocking glasses helped boost melatonin levels and reduce alertness in teenagers, promoting better sleep.
Myopia Risk and Dry Eye
While some research indicates a deficiency in blue light exposure could contribute to increasing myopia in kids, experts warn that prolonged exposure from close-range digital devices may lead to eye strain symptoms like dry eyes, headaches and vision changes.
Blue light stimulates oxidative stress and reactive oxygen species generation in corneal epithelial cells, leading to inflammation and dry eye issues over time.
When should you not wear blue light glasses?
Daytime use and outdoor exposure
Wearing blue light glasses during the day or when exposed to natural sunlight is generally not recommended. Blue light from the sun plays a vital role in regulating our circadian rhythms and daily biological cycles. Blocking this natural blue light exposure can disrupt these processes, leading to potential side effects like sleepiness or fatigue.
Blue light glasses are designed to filter out high-energy visible (HEV) blue wavelengths predominantly emitted by digital screens and artificial lighting. Wearing them outdoors negates their intended purpose and may hinder your body's ability to harness the beneficial effects of sunlight.
Before bedtime and evening use
While blue light glasses can be worn when using digital devices during the day, it's advisable to avoid wearing them in the evening hours, at least 2-3 hours before bedtime. Blue light exposure close to sleep time can suppress the release of the sleep-inducing hormone melatonin, making it harder to wind down and fall asleep.
For better sleep quality, consider using amber or red-tinted "night mode" glasses that specifically target the melatonin-inhibiting blue wavelengths in the 450-500nm range. These are more effective than clear blue light lenses for reducing sleep disruption from evening screen time.
Prolonged daily use
While occasional use of blue light glasses is fine when using digital devices, wearing them for over 12 consecutive hours daily may not be advisable. Moderate blue light exposure is necessary to maintain our natural rhythms and energy levels. Prolonged blocking could lead to potential side effects like fatigue or disrupted sleep cycles.
If you experience frequent dry eyes or eyestrain from extended screen time, taking regular breaks, using artificial tears, and getting an eye exam may provide more relief than relying solely on blue light glasses.

Can wearing blue light glasses prevent or delay eye diseases in kids?
Blue light glasses have become popular for kids who spend significant time on digital devices. But can they actually prevent or delay vision problems?
Potential Benefits
While blue light from screens is unlikely to physically damage eyes, prolonged exposure may cause issues like digital eye strain. Blue light glasses filter out blue-violet wavelengths that contribute to this discomfort. Wearing them can help reduce dry eyes, headaches, and fatigue from extended screen use.
Additionally, blue light at night can disrupt circadian rhythms and sleep cycles. Blue light blocking glasses may improve sleep quality by filtering stimulating wavelengths before bedtime.
Limitations
However, there is no definitive evidence that blue light glasses prevent or delay eye diseases in kids. They only reduce symptoms related to blue light exposure.
While helpful, glasses alone cannot prevent issues like nearsightedness or astigmatism. The American Academy of Ophthalmology states regular eye exams are crucial to detect vision problems early.
Additionally, not all blue light glasses effectively block the most disruptive wavelengths. An eye doctor can ensure the right lenses are prescribed.
Tips for maintaining kids' eye health while using digital devices
Encourage Blinking & Breaks
Prolonged screen time can lead to dry eyes and eye strain in kids. Remind them to blink frequently when using digital devices like computers or tablets to keep their eyes moisturized. Taking breaks every 20 minutes and looking at distant objects helps reduce eye fatigue. Follow the 20-20-20 rule: look at something 20 feet away for 20 seconds after every 20 minutes of screen use.
Adjust Brightness & Position
Glare and reflections from screens can contribute to eye discomfort. Adjust screen brightness to match ambient lighting and use night mode features, especially in the evening. Position screens at a comfortable distance, usually an arm's length away, with kids gazing slightly downward to minimize strain.
Monitor Time & Environment
While not directly harmful, excessive screen time in young children can lead to issues like myopia and attention problems. Set clear boundaries and engage kids in non-screen activities. Ensure proper lighting without glare or reflections when using devices.
Consider Blue Light Glasses
Though research is ongoing, blue light filtering glasses may help reduce exposure to blue light emitted by digital screens. Eclipse Optics offers functional blue light glasses designed for kids to protect their developing eyes during prolonged device use.
