Blue light glasses: why Gunnar has been the reference since 2006
Computer glasses, gaming glasses, optician filters, software apps… The blue light glasses market is flooded with options. But not all of them tackle the real problem of digital eye strain. And only one brand invented the category.
Here is an honest comparison of every available solution — for gamers, digital workers, students, and anyone spending long hours in front of a screen.
Why your eyes suffer in front of a screen: the real causes of eye strain
Before comparing blue light glasses and other solutions, you need to understand the real causes of digital eye strain — because that is where most products on the market fail.
Cause #1: Accommodation effort and ciliary muscles
This is the primary cause of eye strain, and yet the most overlooked. When you look at a screen 50–70 cm away, your ciliary muscles maintain a constant accommodation effort to focus at near distance. Over a full workday or a long gaming session, this muscular effort generates real fatigue: sore eyes from computer use, blurred vision, screen headaches.
Blue light is not the cause. It is the continuous muscular work of your eyes to accommodate at close range.
Cause #2: Dry eyes and reduced blinking
In front of a screen, we blink far less often. The tear film evaporates faster, causing dry eyes from screen use, stinging, and redness. Ambient airflow — air conditioning, fans — worsens ocular dryness. Contact lens wearers are especially vulnerable.
Cause #3: High-energy blue light (HEV) and circadian rhythm
Blue light concentrated in the 400–450 nanometer (nm) range disrupts the circadian rhythm and melatonin production — causing sleep disruption from blue light after long sessions. Chronic exposure is also associated with long-term retinal risks (macular degeneration).
The Gunnar solution: three problems solved, one product
Gunnar Optiks is the best blue light glasses brand for one simple reason: it is the only brand to have engineered a technology that simultaneously addresses all three causes of screen eye strain.
GUNNAR Focus™ — The technology that truly reduces gaming and office eye fatigue
Most blue light filter glasses simply tint the lenses. They filter blue light to varying degrees — but do absolutely nothing against accommodation fatigue, which is the primary source of discomfort.
Gunnar engineered its blue light blocking lenses with a slight positive correction in diopters. This micro-correction relieves the ciliary muscles by reducing the accommodation effort required for near vision. Your eyes work less. Gaming eye fatigue and office fatigue are significantly reduced.
This is clinically documented — and precisely why Gunnar is the blue light glasses recommended by ophthalmologists. No other brand integrates this ocular focus technology into its standard lenses.
GUNNAR Tint™ — Blue light filtration, precisely calibrated with BLPF™
Gunnar's amber lenses filter harmful blue light through a proprietary spectral filtration system. Gunnar created the Blue Light Protection Factor™ (BLPF™): a precise, independently lab-tested blue light filtration rate — not a vague marketing claim.
| Lens | BLPF™ | Recommended use |
|---|---|---|
| Crystalline — clear blue light lens | 35% | Daytime work, color accuracy (designers, content creators) |
| Amber — signature amber lens | 65% | Gaming, long screen sessions — best-seller for gamers and digital workers |
| Sun | 90% | Outdoor use, sun protection + screens |
| Amber Max | 98% | Hypersensitivity, night use, circadian rhythm control |
All lenses block 100% of UV (UV400). Certified CE and ANSI standard.
GUNNAR Wrap™ — Fighting screen-related dry eyes
The pronounced curvature of Gunnar frames creates an ocular microclimate by reducing airflow around the eyes. Less tear film evaporation, less screen dry eye — whether you're a gamer, streamer, or working from home.
Patent #9417460 — Gunnar is the first and only company to have obtained a US gaming glasses patent for lenses that reduce digital eye strain. This patent has been successfully defended in court multiple times.
Blue light glasses: what other solutions offer
Optician blue light treatments (Essilor Crizal, Zeiss DuraVision…) can be added to prescription lenses, which is convenient. But their blue light filtration rate is only around 10–14%, and they include no accommodation technology. The optician blue light glasses alternative remains limited.
Software solutions (f.lux, Night Shift) are free and useful. But they only work on one screen, degrade color perception, and do nothing against dry eyes or accommodation fatigue.
Generic brands (Amazon and equivalents): unpredictable filtration, no CE certification, no ANSI standard, no verifiable independent lab testing.
Specialized brands like Horus X or Barner offer decent filtration. In a Gunnar vs Horus X comparison, the key difference is clear: their lenses do not address accommodation fatigue. They have existed since 2017; Gunnar since 2006.

The story behind Gunnar Optiks technology
In 2003, Matt Michelsen suffered from severe eye strain after long screen sessions. Together with Joe Croft, a Stanford-trained engineer, and Jennifer Michelsen, he spent three years in R&D to understand the real causes of the problem: hundreds of prototypes, independent lab testing, and consultation with dozens of healthcare professionals.
In 2006, Gunnar Optiks launched from a garage in California. The computer glasses category had just been invented.
When the first challenger brands appeared in 2017, Gunnar already had 11 years of existence, a court-defended optical patent, clinically validated technology, and active partnerships with Activision, Blizzard, and the world's largest esport organizations.
