Blue light is one of the many shades of light rays within the visible light spectrum. Blue light represents about one-third of high-energy visible (HEV) light, and it ranges from about 380 to 500 nanometers (nm) on the spectrum.

The main source of blue light is the sun, which emits natural blue light. However, there are also many man-made sources of blue light, including electronic devices.

TV screens, desktop computers, laptops, tablets, e-readers, smartphones, video games, LEDs, and fluorescent lights all emit artificial blue light. The amount is minimal in comparison to the output found in sunlight. Despite that, the exposure is still significant. That's due to the widespread use of these electronics, the excessive amount of time spent using them, and their proximity to your eyes during use.

Blue light isn’t inherently harmful, but lengthy, repeated exposure to blue light and blue-violet light (415 – 455 nm) can lead to many unwelcome issues. Repeated exposure to blue light may result in symptoms including headaches, mental and physical fatigue, blurred vision, digital eye strain, dry eyes, and poor sleep. Prolonged exposure to harmful HEV blue light can even increase the risk of developing age-related macular degeneration.

Blue light can harm your eyes through internal physical damage and external visual disturbances.

Externally, the short wavelengths of HEV blue light scatter easily, which causes more flickering and creates glare. Those issues reduce visual contrast, clarity, and sharpness on your screens, which makes it harder to focus and contributes to digital eye strain. Excessive eye strain can result in headaches, watery eyes, light sensitivity, double vision, fuzzy sight, and the sensation of burning or itching eyes.

Blue light can also cause internal eye problems, such as retinal damage. Harmful HEV light penetrates to the back of the eye, since the eye's cornea and lens cannot reflect or block it. Repeated exposure can lead to deterioration and macular degeneration.

Reducing the use of devices and lighting that emit harmful blue light rays is the most effective approach. However, many people rely on their electronic tools for work, resulting in many hours of exposure every day. Plus, it's hard to avoid indoor LED and fluorescent lighting that contributes to blue light emissions.

Taking some preventive measures can help limit potential blue light damage. Apply the 20/20/20 rule — look away from your screen every 20 minutes at a focal point 20 feet away for 20 seconds. Scheduled breaks and regular eye exams may also have limited benefits. However, the most effective way to protect your eyes, your vision, and your health from harmful blue light is with blue light filters, like those found in our blue light glasses.

Blue light filters are tools that reduce or limit the amount of blue light that reaches your eyes. Though they don't block 100% of the blue light you are exposed to, a reduction in blue light exposure helps support your natural sleep cycle and protects against eye strain.

Tinted screen covers, glass overlays, and plastic sheets filter blue light for individual devices. Filtering software and display button settings can minimize some blue light emissions for various electronics. Yet, these options are limited, and none address LED and fluorescent lighting.

Blue light glasses are the most effective blue light filter option. You can use digital protection lens technology anywhere, at any time, with an unlimited number of devices.

These glasses have a tinted protective coating that limits the amount of blue light that reaches your eyes. They work in most settings with any blue-light emitting device. They're also called computer glasses, blue light blocking glasses, and blue light glasses.

Blue light glasses help protect your eyes, visual acuity, and health by screening a percentage of the blue light you come in contact with. They let you and your family enjoy your digital devices and use artificial LED and fluorescent lighting without worry of excessive harmful blue light exposure. They're a portable and affordable option that offers versatility and flexibility, unlike blue light filters, which are tailored to specific devices.

Blue light glasses help lessen your exposure to harmful blue light. With this protection, you can perform professional, educational, and recreational activities on your electronic devices without fear of excessive damage from blue light emissions. Digital protection glasses let you engage in essential and leisure pursuits worry-free, as they shield your eyes from harmful blue light.

Natural blue light from the sun helps maintain your internal clock — the daily rhythms of sunlight and darkness signal your body when it's time to wake and when to rest.

To assist with this, your body produces the hormone melatonin naturally to support sleep. Melatonin production is typically higher at night when it's dark. Production drops off as morning approaches and the sun comes up.

Exposure to artificial blue light emitted from electronics and indoor lighting can confuse your internal clock and lower melatonin levels, both of which make you feel more awake, and this can be harmful at night when you're supposed to be winding down for sleep.

If you use digital devices at night, blue light filter glasses can block misleading signals to your body, helping you fall asleep when you're ready. JINS SCREEN Night Use can block 60% of artificial blue light that would otherwise signal your body to decrease melatonin levels. Instead, normal production of this restful, natural sleep hormone continues, supporting your internal clock for a good night's sleep.

No prescription is necessary — you can use blue light glasses whether you have prescription eyeglasses or not.
