Short answer: you can, but for paper books there's little point. A printed page doesn't give off light, it only reflects the light in the room, so there's very little blue light to filter. Blue light glasses make more sense for reading on a backlit screen, and most of all for reading on a phone or tablet in the evening, when an orange lens cuts most of the blue light before bed. If reading is uncomfortable, better lighting or reading glasses usually help more.
Below: when blue light glasses are worth wearing for reading, when they aren't, and what actually makes reading more comfortable.
Reading on Screens vs Reading on Paper
The difference is where the light comes from. A tablet, phone or backlit e-reader shines light toward your eyes, including blue light. A paper book, or an e-ink reader with its light turned off, only reflects the light already in the room.
That's why blue light glasses have a clearer role for screens than for paper.
Reading on a Screen: Where Blue Light Glasses Fit
Screen Comfort
Long stretches of reading on a screen can leave your eyes tired or dry. That's mostly down to focusing up close for a long time and blinking less, not blue light itself. A 2023 Cochrane review found blue light filtering glasses probably make no difference to eye strain in the short term. Some people simply find a warmer-looking screen more comfortable to read, and that's a fine reason to wear them.
Reading in the Evening
This is where blue light glasses have a clearer purpose. Bright, blue-rich light in the evening can delay the rise of melatonin, the hormone that tells your body it's getting dark. If you read on a phone or tablet in bed, an orange lens cuts most of that blue light. Ours blocks 99% of light across 380–550nm, as measured by Micro-Light Optics. For the last hour before sleep, a red lens blocks 99.7% across 380–580nm.
Sleep depends on much more than light, so treat them as one part of a wind-down routine rather than a fix.
Screen Glare
Glare comes from reflections on the screen and from a screen that's much brighter than the room. Blue light glasses don't remove reflections. Moving the lamp, tilting the screen and matching brightness to the room do more.
Better Habits for Reading on Screens
Use Your Device's Settings
Most phones, tablets and e-readers have a night mode or warm light setting. Set it to come on automatically in the evening, and turn brightness down at night. On a computer, tools like f.lux do the same.
Rest Your Eyes
Use the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. If that feels like too much while reading, just look up from the page at the end of each chapter.
Blink More
We blink far less when we concentrate on a screen. Make a point of blinking fully, and if your eyes feel dry, lubricating eye drops can help.
Make the Text Bigger
Increasing the text size means less squinting and less leaning in. It's one of the easiest comfort fixes on any e-reader.
Reading Physical Books
For paper books, blue light glasses don't add much. The page only reflects the room's light, and the blue light reaching your eyes is small. If you're reading under bright lighting late in the evening, the light in the room matters more than the book, so a warmer, dimmer lamp is the better fix.
What Actually Makes Book Reading Uncomfortable
- Poor lighting: too dim, too harsh, or casting a shadow on the page. Use a good reading lamp positioned to the side.
- Uncorrected vision: if small print is getting harder, you may need reading glasses or an updated prescription. An eye exam will tell you.
- Dry, tired eyes: long sessions without breaks. Look up from the page now and then.
If you need reading magnification and want a blue light filter for screens too, our ReadAid reading glasses combine both, with a clear lens that blocks 35% of blue light across 400–500nm.
Frequently Asked Questions
Are Blue Light Glasses Good for Reading?
For reading on screens in the evening, an orange or red lens cuts most blue light before bed. For paper books, they add little.
Should I Wear Blue Light Glasses When Reading a Kindle?
It depends on the light. An e-ink Kindle with its light off doesn't give off light, so there's nothing to filter. If you use the built-in light at night, turn on its warm light setting if it has one, or wear an orange lens.
When Should You Not Wear Blue Light Glasses?
Skip tinted lenses in very dim light, for tasks where accurate color matters, such as design or photo editing, and for driving at night.
Can You Wear Blue Light Reading Glasses All the Time?
Clear blue light reading glasses are fine to wear whenever you're reading. There's no extra benefit to wearing them away from screens, though.
Conclusion
Blue light glasses are worth wearing for reading on screens, especially in the evening, when an orange or red lens cuts most blue light before bed. For paper books, they add little. Good lighting, regular breaks, larger text and an up-to-date prescription make the bigger difference to how comfortable reading feels.
