Gunnar is best known for its blue-light-blocking computer glasses designed for gamers. If you go to major video game events like PAX, you've probably seen a pair.

Gunnar offers a variety of frames, including several collaborations like the Fallout Lucky 38 pictured above, from Fallout on Amazon Prime Video (and, originally, the Fallout game series). You also get a choice of tint types, including the slight clear lens that blocks 35% of blue light and doesn't tint other colors too much; the more intense amber lens that blocks 65% of blue light; and even transition lenses that stay tinted indoors and get darker like sunglasses when you're outside. These glasses are available with or without a prescription. If you're farsighted, though, know that "Gunnar-Focus" glasses have a slight magnifying factor that can be a bit disorienting; if you don't want that, make sure you order "Natural-Focus" lenses.

We've tried several pairs of Gunnar glasses, and each has been well-made, sturdy, and comfortable.

Jins is a Japanese eyewear brand that offers a variety of blue-light-blocking lenses. There are five Jins Screen lens treatments: Jins Screen Daily Use, Jins Screen Heavy Use, Jins Screen Night Use, Blue Light Invincible, and Ultra Thin Screen Daily.

The regular Jins Screen Daily Use models feature a subtle tint that blocks 25% of blue light, the Jins Screen Heavy Use lenses opt for a slightly stronger, greenish tint that blocks 40% of blue light, and the Jins Screen Night Use lenses are more of a typical amber tint and block 60% of blue light. These treatments are $60 each (plus the price of the frames), though Night Use lenses are only available in-store, of which there are just six in the United States, all in California (four in Los Angeles, two in the Bay Area).

Blue Light Invincible ($160) and its high-index variant, Ultra Thin Screen Daily ($410), have the lightest tints, blocking 12% of blue light. They're also much more expensive, with both lens types manufactured in Japan and featuring a three-layer coating that is more scratch-resistant, reflects less glare, and attracts less dust than other Jins lenses.

You can add any of the five to most frames. The frames themselves are quite nice, but they can also get pretty expensive, especially if you want a model that's actually made in Japan.

Zenni is a glasses brand that lets you order inexpensive frames and lenses online. If you have your prescription, you can simply enter the numbers into a form, and your glasses will arrive a few weeks later. With prices starting at $7, I've sworn by Zenni for stocking up on backup glasses, though its pricier frames and lenses are generally pretty well-made, too.

Zenni offers Blokz, its own blue-light-blocking lens technology. Blokz lenses start at $17, so you can get prescription blue-light-blocking glasses for as little as $25. You can also get photochromatic Blokz that darken in the sunlight, and Zenni recently released its EyeQLenz lenses that filter blue light and infrared light, and have photochromatic properties (though in my tests they don't get sunglasses-dark).

Warby Parker is one of the more popular fashion-focused glasses retailers because of its home try-on policy. You pick five frames online to try on at home, the company ships them to you, and you choose which ones to keep. The frames are made well, reasonably priced, and support blue-light-filtering lenses. The coating is an extra $50, which puts most glasses at around $145 (or less if you have an eligible insurance plan). You can also get anti-fatigue lenses for $100 more, which add a slight magnification effect to the lower part of the lens. We can't speak to their effectiveness, however.

You can get inexpensive blue-light-blocking glasses at Amazon and other retailers, though you won't have the benefit of prescription lenses. We also haven't reviewed any of these glasses, so we can't attest to their lens or frame quality. We have, however, noticed an interesting pattern: Lots of them are the same.

The glasses above appear to be identical to several of the glasses a few entries below them when you search for blue-light-blocking models on Amazon. We suspect most of these glasses come from the same factory and that the different brand names don't mean much. If you don't recognize the brand and the company doesn't appear to have a dedicated website, expect a generic experience.

You don't need glasses to reduce blue light on your screen. iPhones, Macs, PCs, and most Android phones have night modes that significantly warm up the white balance of the screen to reduce eye strain. On Windows 10 and 11, it's called Night Light, and on iOS, iPadOS, and macOS it's called Night Shift. You can set these modes to work on a schedule or based on sunrise and sunset times.

You can also use f.lux, free software for Android, iOS, macOS, and Windows, which does the same job.

Ironically, the popular-in-drug-stores brand BluBlocker is not advisable for reducing blue light when staring at a screen.

BluBlockers are sunglasses, and their tints are too strong for comfortably looking at your monitor. If you use too strong a tint, you can strain your eyes in the other direction, forcing them to deal with too little light instead of too much.
