Blue Light Filtering Options: A Guide to Zenni’s Blokz™Lenses
In today’s digital age, where digital devices are omnipresent, shielding your eyes is a priority for many people. Zenni offers a range of Blokz lenses designed to filter blue light without compromising on style or clarity. Whether you’re looking for everyday defense or a specialized solution, Blokz offers a lens to suit your needs.
Understanding Blue Light: Sources and Wavelengths
Blue light is a high-energy, short-wavelength band of visible light, generally defined as falling between 380 and 500 nanometers (nm). Digital devices and LED lighting are common everyday sources, but sunlight is actually the largest source of blue light you’re exposed to each day. That’s part of why Zenni recommends Blokz lenses for outdoor activities too, since every Blokz option includes UV protection alongside blue light filtering.
Blokz Standard: Everyday Protection
Ideal for all ages, Blokz Standard lenses filter more blue light than regular optical lenses. These virtually clear lenses are perfect for extended computer use, offering comprehensive defense for daily activities. Available in single vision, progressives, bifocals, and non-prescription options, they help keep your eyes comfortable all day.
Blokz More: Independently Tested Defense
For those who want extra assurance, Blokz More lenses use a special coating that reflects the 440-450 nm range of the blue light spectrum, the range where many digital devices’ blue light energy peaks. Zenni sent Blokz More to COLTS, an independent testing laboratory, which validated that these lenses provide up to 2 times more defense at 450 nm than Zenni’s original Blokz Core lens, along with 100% UV protection.
Blokz Plus Anti-Fatigue: Visual Boost for Eye Relief
For those who spend extensive hours on digital devices, Blokz Plus Anti-Fatigue lenses filter more blue light than Blokz Core lenses. These yellow-tinted lenses help give your eyes a break by offering subtle magnification. Their innovative design ensures a comfortable view with reduced glare, making them ideal for digital lifestyles.

A Simple Habit Worth Pairing With Blokz: The 20-20-20 Rule
Since eye care experts point to screen habits, not blue light, as the main driver of digital eye strain, it’s worth pairing your Blokz lenses with the 20-20-20 rule: every 20 minutes, look at something roughly 20 feet away for at least 20 seconds. This gives your eyes a break from close-up focus and encourages more frequent blinking, which is one of the most effective ways to ease digital eye strain.
Whether you’re seeking everyday protection, specialized anti-fatigue solutions, adaptive photochromic options, robust sunglasses, or impact-resistant clarity, Zenni’s Blokz lenses offer a comprehensive range to safeguard your eyes in any environment. Explore the full spectrum of Blokz lenses today and discover the perfect blend of eye health, style, and functionality for your lifestyle.
FAQs
Do blue light blocking glasses actually work?
It depends on what you’re hoping they’ll do. Blokz lenses reliably filter a measurable portion of the blue light spectrum and include 100% UV protection, both of which are independently verifiable. Whether blue light filtering meaningfully reduces digital eye strain is less settled: a 2023 Cochrane review of 17 studies found no significant difference in eye strain symptoms compared to regular lenses. Many people still find Blokz lenses more comfortable for digital device use, and some wear them on their eye doctor’s recommendation.
Does blue light from screens damage your eyes?
Major eye health organizations, including the American Academy of Ophthalmology, have not found evidence that the blue light emitted by digital screens damages the eyes. Lab studies showing blue light toxicity to retinal cells typically use direct, concentrated light exposure that doesn’t match everyday screen use, and screens emit far less blue light than sunlight does.
What is the 20-20-20 rule, and do I still need it if I wear Blokz lenses?
The 20-20-20 rule means looking at something about 20 feet away for 20 seconds every 20 minutes you spend on a screen. Since most digital eye strain comes from reduced blinking and prolonged close focus rather than blue light itself, this habit is worth keeping up even if you wear Blokz lenses.
Can kids wear Blokz lenses?
Yes. Blokz Trivex lenses are impact-resistant and lightweight, making them a popular choice for kids as well as adults, and Blokz Standard is available for all ages.
