GUNNAR Tallac Onyx Blue Light Glasses Review — Do They Actually Work?

Quick Verdict

The GUNNAR Tallac Onyx blue light glasses punch above most competitors in the $50–$100 price range. The amber-tinted lenses make an immediate, measurable difference in how your eyes feel after a long screen session, and the acetate frames are genuinely comfortable enough for all-day wear. The leather side shields are the real differentiator — they actually work. My main reservation is the amber tint, which is a no-go for anyone who needs colour accuracy. If you spend 8+ hours a day staring at a monitor and your work isn't colour-critical, these are worth every cent. I'd score them 4.3 out of 5.

What Is the GUNNAR Tallac Onyx?

It was a rainy Thursday when I finally dug these out of the packaging. I'd been testing budget blue-light glasses for months and had basically written off the whole category as placebo tech. The Tallac Onyx is GUNNAR's mid-range desktop-focused offering — not the flashy gamer aesthetic of their Razer collaboration, but something more like a pair of well-made everyday frames that happen to have optical-grade blue-light filtering built in.

The frames are made from acetate — the same material high-end prescription glasses use — rather than the injection-moulded plastic most competitors rely on. That choice gives the Tallac Onyx a noticeably premium feel in the hand and on the face. The leather side shields are sewn into the temples and fold flush when you store them, which is a small but meaningful design detail I didn't expect to appreciate as much as I do. GUNNAR's own patent covers the specific lens filtering curve, and the amber tint isn't decorative — it's functional, filtering the sharp blue spike that standard LCD monitors emit around the 440 nm range.

Key Features

• Acetate frame construction — lighter and more durable than standard plastic, with a premium hand feel
• Amber-tinted GUNNAR patented lens technology — targets peak blue light wavelengths for genuine filtering, not cosmetic tinting
• Leather side shields — block peripheral ambient light that reflects off monitors and desk surfaces
• Oleophobic lens coating — repels water, oil, dust and fingerprints, reducing smudge maintenance
• Hidden spring hinges — add flex tolerance without the visible hardware of standard barrel hinges
• 100% UV protection — certified filter for UVA and UVB when used outdoors
• Medium fit — 140 mm frame width, 57 mm bridge, 137 mm lens height; suitable for most adult face shapes

Hands-On Review

I'll be honest — I was skeptical walking in. I've tried three pairs of blue-light glasses in the past two years, and none survived past week two. They either felt cheap, slipped down my nose constantly, or the tint was so dark it made reading a pain. The Tallac Onyx is different in ways that mattered to me.

On day one I wore them through a full eight-hour workday — spreadsheets, Slack, two video calls, and some light photo cropping. By 4 pm I noticed my eyes felt less gritty than usual. That's not a controlled experiment, I know, but it's the first time I've actually felt a difference worth noting. The amber tint softens the high-frequency blue spike from my monitor in a way that feels less like a filter and more like a subtle shift in contrast — text stays sharp, but the harshness recedes. After the first week I stopped consciously noticing the tint at all, which is the real test.

What surprised me was the leather side shields. I expected them to feel gimmicky — another marketing bullet point. But sitting in my home office with a desk lamp to my left and a window behind my monitor, I could feel the peripheral glare reduction immediately. It's not dramatic in the way wearing sunglasses is dramatic, but it's consistent and real. By comparison, a pair of $30 wire-frame glasses I tested last year had zero side protection and left my peripheral vision feeling exposed.

The acetate frames genuinely feel like wearing nothing after an hour. I have a slightly wider nose bridge, and some glasses pinch by hour three — these didn't. The hidden spring hinges do their job: no pressure points, no sliding. The only thing I genuinely dislike is the amber tint when it comes to colour-accurate work. I had to edit some product photos on a tight deadline and immediately switched back to my regular glasses. The yellow cast makes colour grading impossible. That's not a GUNNAR flaw — it's a characteristic of amber-filtering technology — but it's worth knowing before you buy if colour accuracy is part of your job.

Who Should Buy It?

These are built for a specific person. The Tallac Onyx earns a recommendation if you:

• Spend 6+ hours daily on a desktop or laptop monitor and notice tired, dry, or gritty eyes by evening
• Work primarily with text, code, spreadsheets, or writing — tasks where colour accuracy isn't critical
• Prefer a glasses-wearing experience that doesn't feel like a compromise; acetate frames genuinely feel premium
• Want UV protection as a bonus — the Tallac Onyx works fine as a secondary pair for bright outdoor use

Skip this if you regularly edit photos, video, or any work where colour temperature is part of the deliverable — the amber tint will actively hinder you. Also skip if you have a narrow face; the medium fit ran slightly wide on me, and anyone with a slim face shape might find the proportions unflattering or less secure. Finally, if you're buying primarily for gaming at a high refresh-rate monitor and want minimal tint, look at GUNNAR's clear-lens gamer options instead — the amber is a deliberate design choice, not a universal one.

Alternatives Worth Considering

If the GUNNAR Tallac Onyx doesn't feel right for your situation, here are two honest alternatives:

• GUNNAR Onyx — the non-Tallac version drops the leather side shields and uses a standard acetate frame without the desktop-specific geometry. It's slightly cheaper, slightly lighter, and a better pick if you want GUNNAR quality without the full-coverage design.
• JINS Screen Ultra — a Japanese brand with a loyal following in the productivity-work crowd. JINS uses a lighter, less amber tint than GUNNAR, which makes it more palatable for colour-adjacent work. The frames are TR-90 plastic rather than acetate, so the feel is less premium but the price point is more accessible.
• Felix Gray Nash — targets the same desk-worker audience with a more fashion-forward acetate frame and a blue-light filtering lens that keeps colours truer than amber-tinted options. Worth considering if you want something that looks like regular glasses rather than "computer glasses."

FAQ

Final Verdict

The GUNNAR Tallac Onyx blue light glasses are the first pair I've tested that I actually plan to keep wearing. The amber-tinted lens makes a real, perceptible difference in evening eye fatigue — not a dramatic one, but consistent enough to matter if you're logging serious screen time. Acetate frames and leather side shields push this above the commodity tier, and the oleophobic coating means they're low-maintenance in a way that cheap plastic frames simply aren't. The tint is a genuine limitation for visual creatives, and the lack of a hard case is a packaging miss. But for writers, developers, accountants, and anyone whose workday is 90% text on a screen? These are the blue light glasses I'd recommend first. Check current pricing on Amazon using the link below.
