Interest in Blue Light Contacts Is Growing, But What Do Filtering Lenses Actually Do?
Screen time has many people asking whether their contact lenses can do double duty by filtering blue light along with correcting vision. The answer depends on the lens, the brand and what you can realistically expect blue light filtering to accomplish.
Can Contact Lenses Block Blue Light From Screens?
Yes, blue light filtering contact lenses exist and can absorb a portion of the high-energy visible light emitted by phones, tablets and computer screens. The amount filtered varies by brand, ranging from about 15% indoors to more than 50% in bright outdoor conditions for adaptive lenses.
These lenses use specialized materials or additives built into the lens itself to absorb light in the 380 to 460 nanometer wavelength range, according to Greenwich Ophthalmology Associates. The technology has expanded beyond eyeglasses, giving contact wearers a similar option without needing additional eyewear over their lenses.
Still, the clinical evidence is developing. The American Academy of Ophthalmology has noted that blue light from digital screens has not been shown to cause retinal damage or eye disease, and most research points to reduced blink rates and sustained near focusing as the bigger drivers of digital eye strain.
Which Contact Lens Brands Offer Blue Light Filtering?
Acuvue Oasys MAX 1-Day and Biofinity Energys are two of the better-known brands offering blue light filtering contact lenses. Acuvue uses a technology called OptiBlue that filters up to 60% of blue light while also providing built-in UV protection.
According to the Warby Parker product page, Acuvue Oasys MAX 1-Day contacts also include a moisture technology called TearStable and block 82% of UVA rays and 97% of UVB rays. The retailer describes it as “an ideal lens for someone who wants to try daily disposable lenses for the first time.”
Biofinity Energys lenses go a step further by combining blue light filtering with hydration features designed to reduce the dryness many wearers experience after long stretches of screen time. According to Web Eye Care, “Users report that they can wear these lenses longer than traditional contacts without eye fatigue.”
Are Blue Light Contacts Better Than Blue Light Glasses?
Blue light contacts and blue light glasses each have advantages, and the right choice often comes down to convenience and what eyewear you already own. Contacts correct vision and filter blue light in one nearly invisible package, while glasses can be worn over existing contacts.
“Blue-violet light contacts are very convenient, since they not only protect your eyes from blue-violet light and correct your vision, but they are also nearly imperceptible when you wear them, unlike glasses,” Contacts Direct explains. The retailer notes that wearers who already have a supply of regular contacts can simply pair them with non-prescription blue light glasses.
Regardless of which option you choose, eye care professionals recommend swapping in fresh contact lenses on schedule and following your doctor’s guidance on wear time. Skipping replacements can cause irritation that no amount of blue light filtering will fix.
Is All Blue Light Bad for Your Eyes?
No, not all blue light is harmful. High-energy visible light plays a role in alertness, memory, cognitive function and mood regulation, and it is even used as a treatment for Seasonal Affective Disorder, according to the Raleigh Eye Center.
Blue light also helps regulate the circadian rhythm. Daytime exposure supports the body’s natural sleep-wake cycle, while too much blue light at night, such as from a tablet or e-reader at bedtime, can disrupt sleep. Most blue light exposure actually comes from sunlight, not screens. Phones and computers emit only a fraction of the sun’s blue light, but they sit close to the face for hours at a time, which is why they get singled out as harmful.
A 2018 study published in the International Journal of Ophthalmology found that blue light can support refractive development and circadian regulation but may also cause varying degrees of damage to the cornea, lens and retina, particularly with heavy nighttime use.
