What Is The Best Color Light For Reading And Studying

If you find yourself reading and studying a lot, or simply in front of the computer for long periods - you need to take care of your eye health.

You might find that you start developing digital eye strain or just regular eye strain from reading and studying in the wrong conditions for your eye health.

This article breaks down the fundamentals of eye health for the best reading and studying conditions to keep your eyes healthy and happy.

What Is The Best Color Light For Reading And Studying During The Daytime?

It is best to study and read in natural light during the day, and protect yourself from artificial blue light sources if using technology such as laptops, computers, tablets, and kindles.

You want to take a few different factors into account when choosing the best color light for reading and studying. Such as if you’re studying and reading during the daytime or during the evening. And it also depends on the modality of studying and reading, for example, if you are using a paperback book, or a piece of technology that emits LED light wavelengths such as a laptop, tablet, or kindle.

It is best to read and study in natural light during the daytime, irrespective of if you are using a paperback book or technology. Because natural light emits natural blue light wavelengths that promote alertness and also can enhance your ability to focus on performance-based tasks that require sustained attention.¹ Natural blue light is extremely important for a healthy functioning biological system.

But there are issues with using technology during the daytime because LED light sources (such as a tablet, kindle, and computer screens) emit artificial blue light wavelengths. Over-exposure to artificial blue light wavelength is known to cause a wide range of emotional, mental, and physical health issues.


The human body works on a circadian rhythm that is regulated by the hormone melatonin. Natural blue light is emitted from the sun, and as the sunlight disappears this triggers the body’s natural levels of melatonin to rise during the evening. This increase of melatonin allows us to feel peaceful, relaxed, and sleepy as we prepare to snuggle down for bedtime and undisturbed sleep.

As the sun rises in the morning the body is triggered into alertness due to the rise in blue light wavelengths and the lowering of melatonin levels, and we wake up ready for the day. Well, some of us are not so ready first thing in the morning - but you get the idea.

Now, artificial LED light sources, such as TV screens, smartphones, lamps, lightbulbs, fluorescent office lights, tablets, kindles, computers, and laptops emit artificial blue-light wavelengths that can affect our body’s natural hormone balance. They confuse the body with artificial blue light wavelengths that disturb the natural rise and fall of melatonin levels.

So even during the day, it’s important to be aware of your exposure to blue light wavelengths and LED light sources. If you are studying during the day using technology then make sure to invest in some blue-light-blocking glasses. You can find our recommendations on the Best Clear Blue Light Blocking Glasses For Daytime use here.

What Is The Best Color Light For Reading And Studying During The Nighttime?

Amber light and red light from Blue Light Blocking Lightbulbs are the best color lights for reading and studying at nighttime because they don’t affect your circadian rhythm or disrupt hormone balance. If you are reading from a printed book then amber or red light bulbs that are formulated to block blue light will suffice.

But if you are reading from an LED light-emitting device such as a computer, laptop, tablet, kindle, or smartphone then it’s important to wear blue-light-blocking glasses too.

Clinical research shows that when reading on a light-emitting device before bedtime that participants didn’t feel as relaxed or sleepy, took longer to fall asleep, and were impaired and less alert the morning after, in comparison to reading a printed book.² The LED light-emitting devices were also emitting blue light wavelengths which disrupted melatonin hormone balance.

They noticed in the study that melatonin levels were not as high, including the circadian rhythm being affected. The research shows that it is important to protect yourself from blue light wavelengths during the day, but also especially after the sunsets. Blue light wavelengths emitted from LED lights can disrupt your hormone balance, sleep pattern, and other natural biological function by preventing the natural increase of melatonin that should happen in the evening.

Red Lens Anti-Blue Light Glasses and Red Light Bulbs that block blue light are the most effective to use at night time because they block blue light and green light wavelengths. Green wavelengths are not often talked about but they are just as important in terms of disrupting normal hormonal patterns that can have a variety of negative health effects (the same as blue light wavelengths).

If you aren’t keen on the decreased visibility of  Red Lens Anti-Blue Light Glasses and Red Light Bulbs then Amber Lens Anti-Blue Light Glasses and Amber Light Bulbs are a much better option for you. However, amber-lens blue-blocking glasses and blue-blocking amber light bulbs do not hold as much protection as the red options available.
