The best e-reader for most people is the Amazon Kindle Paperwhite . It offers the most balanced combination of sharp text performance, battery life, and waterproof capability at a reasonable price point. However, if you prefer a system outside of Amazon's ecosystem or want color capabilities for graphic novels, other specialized options are better suited for you.
Kindle Paperwhite (12th gen) — the safest all-around choice. It has a 7" 300-ppi screen, warm lighting, waterproofing, USB-C, and very long battery life. Current reviews continue to put it among the strongest choices for straightforward book reading.
Kobo Libra Colour - $259.99 (Best Buy)
Kobo Libra Colour — the more feature-rich alternative. It has a 7" color display, physical page-turn buttons, 32 GB storage, waterproofing, and optional stylus support. It also integrates with library borrowing through OverDrive/Libby. WIRED and TechRadar currently put it at or near the top of their e-reader guides.

Want to take handwritten notes: Kobo Libra Colour or a larger Boox/Kindle Scribe
So, if you tell me your budget (e.g. under $150, $200, $300) and what you mainly read—novels, PDFs, comics, textbooks, library books—I can tell you which specific model I'd buy.
If eye strain is your main concern, look for E Ink e-readers with adjustable warm front lighting rather than tablets. E Ink displays are reflective like paper; the built-in light is a front light that illuminates the page rather than shining a bright LCD-style image directly into your eyes.
One important detail: no front-lit e-reader with its light turned on is truly “zero blue light.” The LEDs can still emit some blue-spectrum light, but warm-light modes shift the color temperature toward amber and reduce the blue portion. The only way to have essentially no emitted blue light is to turn the front light off and read under an external warm lamp.
Good options to consider:
Brand/model
Warm light / blue-light control
Why it may help with eye strain
Kobo Clara BW
ComfortLight PRO (adjustable warmth)
Monochrome E Ink screen, simple reading-focused device, good choice if you mostly read novels.
Amazon Kindle Paperwhite
Adjustable warm light (white-to-amber)
Popular, easy to use, 7-inch glare-free E Ink display.
Kobo Libra Colour
ComfortLight PRO
Larger screen and physical page-turn buttons; color E Ink may be less ideal if maximum eye comfort is the goal.
BOOX e-readers
Many models offer separate warm/cool front-light controls
More adjustment options and Android flexibility, but more like a tablet and potentially more distracting.
reMarkable 2
No built-in front light
No screen-emitted light at all; requires room light or a lamp.
For your specific goal—less eye strain and the least blue light possible—I would look first at:
Kobo Clara BW — best if you want a simple, paper-like reading experience with warm lighting.
Kindle Paperwhite — best if you already use Kindle books or want the easiest mainstream option.
reMarkable 2 — best if any glowing screen bothers you and you can read with a lamp.
A few settings that often reduce discomfort:
Use the warmest light setting rather than a bright white setting.
Lower brightness more than you think you need.
Increase font size and line spacing to reduce focusing effort.
Try reading with the front light off in daylight or under a warm lamp.
Avoid color E Ink models if your priority is the most paper-like reading experience.
If you tell me whether you read mostly at night in bed, during the day, or for hours at a desk, I can narrow this down further.
If you are dealing with eye strain, switching from a phone, tablet, or backlit computer screen to an E Ink e-reader is a massive game-changer. E Ink technology reflects ambient light like real paper rather than shining light directly into your eyes.
When looking for devices with warm light adjustment (which shifts the front-light spectrum away from harsh blue wavelengths toward an amber/orange hue), several major brands and models stand out:
Amazon Kindle Paperwhite & Paperwhite Signature Edition: Amazon builds adjustable warm light directly into the current generation. You can manually adjust the warmth or schedule it to change automatically with the sun, drastically cutting down blue light exposure during evening reading.[1][2]
Rakuten Kobo (Clara BW, Clara Colour, Libra Colour): Kobo uses a technology called ComfortLight PRO across most of their modern line. It lets you fine-tune both brightness and color temperature, and it can automatically reduce blue light as your local bedtime approaches.[1][2]
Boox (Palma, Note Air series): Boox makes Android-based E Ink devices that offer granular, independent controls for both warm (amber) and cool (white) front-lights. You can completely dial down the blue-toned LEDs in favor of a warm, paper-like glow.
PocketBook (Era, Verse Pro): PocketBook features SMARTlight technology on their mid-to-high-tier e-readers, allowing you to seamlessly adjust the color temperature and intensity of the front-light to minimize eye fatigue.
Note on "No Blue Light": While these devices feature warm-light LEDs that dramatically reduce blue light emissions compared to standard screens, turning the front-light completely off and reading under an external warm incandescent or soft-white desk lamp will eliminate device blue light entirely.
Would you prefer an e-reader tied to a specific ecosystem (like the Kindle/Amazon store vs. open formats like Kobo or Boox that support ePub and library apps), or do you have a preferred screen size in mind?
