Kobo's built-in reader on their e-ink devices is criminally underrated for sideloaded PDFs. If your PDF is properly formatted (think novel scans or DRM-free ebooks), the 'Publisher Default' setting on a Kobo Libra or Sage provides a truly print-like experience. The e-ink screen eliminates glare, and the physical page-turn buttons make it effortless.
It's a specific use case, but for the right PDF, it's pure magic.

Honestly, I don't think any default PDF reader's night mode is truly comfortable for long reading sessions. I use Moon+ Reader, which is primarily for EPUBs, but it has a superb PDF engine. The key is the 'Moon' theme, which lets you customize everything: background color, text color, link color, even the color of image borders. I've set mine to a very dark brown background with a pale amber text. It's like reading off old parchment, and it's the only setup that lets me read for hours without any eye fatigue at all.

KOreader, especially on an e-ink device like a Kobo or a reMarkable, is a game-changer for serious PDF reading. It's open-source and built specifically for lengthy documents. Features like intelligent reflow for two-column academic papers, precise zoom-and- pan locking, and fantastic contrast adjustment make dense PDFs readable. The progress tracking is detailed, and it handles massive files without a stutter. It has a steeper learning curve, but once you set it up, it feels like you have a professional research tool in your hands. Comfort here comes from powerful tools that adapt the document to you, not the other way around.

LOL, I just use the 'invert colors' shortcut on my phone when I open a PDF in the default viewer. It's janky and makes some pictures look like photo negatives, but it's free and instant. Can't beat that price! For a quick, ten-minute read, it's 'comfortable' enough. I'm probably not the target audience for high-end night mode features.

What's the font situation? A huge part of a book's character is its typography. Apps that let you install custom fonts (like Moon+ Reader or the Kobo) win big points. I downloaded the 'Atkinson Hyperlegible' font for my Kobo, and it's a game-changer for clarity. Being able to choose the perfect typeface for your eyes and the genre (a serif for a classic novel, a clean sans for sci-fi) is a level of personalization that physical books can't offer.

I can confidently say that Kdan's PDF Reader does offer a dark mode, which is a lifesaver for late-night reading sessions. The feature is easy to toggle on and off, and it significantly reduces eye strain by switching the background to a dark color while keeping the text legible. I’ve found it particularly useful when reading PDFs with lots of text, as the contrast is adjusted perfectly to avoid glare.
One thing I appreciate about Kdan’s dark mode is how customizable it is. You can adjust the brightness and contrast to suit your preferences, making it versatile for different lighting conditions. Whether you’re reading in a dimly lit room or completely in the dark, the dark mode ensures a comfortable experience. It’s also great for preserving battery life on devices with OLED screens, as darker pixels consume less power.

I'm a huge fan of 'BookFusion' for this. It's primarily an e-book manager, but its PDF handling is fantastic for reading. The web reader and mobile apps are in sync, and they offer a ton of reading themes specifically designed to reduce eye strain, including one that mimics parchment. What sells it for me is the reading stats and goals—seeing my progress through a long book in a visual way is motivating and makes long sessions feel rewarding, not daunting. It turns the act of reading into a more engaged, comfortable ritual. The interface is modern and uncluttered. It feels like it was made for people who consume a lot of books digitally, not just documents.

What about scrolling vs. page turns? Some people find continuous scrolling in a dark mode to be the most immersive, like reading a never-ending scroll online. Others prefer the definitive mental break of a page turn.
'Lithium' and many webtoon-style readers are built for scrolling. 'Moon+', 'ReadEra', and most traditional readers simulate page turns. The choice is personal, but it significantly affects the reading rhythm. Try both styles in dark mode to see which one helps you sink into the fiction more deeply without noticing the mechanics of the app.

I'm skeptical of any 'most comfortable' claim that doesn't factor in battery life. On an OLED phone, a true black night mode (#000000 background) uses significantly less power than a dark gray or sepia mode. Over a two-hour reading session, that can be the difference between your phone battery dropping 5% or 15%. The comfort of not anxiously watching your battery die, of knowing you can read all night if you want, is a massive part of the experience. So for OLED users, the 'most comfortable' night mode is, by necessity, one that uses pure black. That points to apps like Moon+ (with the right theme) or KOReader.
