One option is to use a blue-light-free book light to read in bed. If you are wondering how do I know if a light is blue light free or not? Then, check the color temperature of that light, as it indicates the amount of blue light in any light. Less color temperature indicates less blue light.

I would recommend getting book reading lights with color temperature lesser than 3000K. 2700K is even better. These are commonly called eye care warm book reading light.

The best option, having minimum amount of blue light with color temperature of below 2000K, is amber color book light. Its color is same as the color of the flame of the candle light.

Here are the best options:

  1. Warm Color – You can get double head both warm and cool color, Ecologic Mart eye care book light, or you can get single head Luminolite book light are great options.
  2. Amber Color – Somnilight amber color rechargeable clip-on amber book light is the best option.

How blue light affects sleep?

Modern science proves that the blue light disturbs our sleep rhythm. It is present in book lights, LED Tvs and other any light that has a color temperature of more than 3000K.

You will be amazed to know that the nature has a subtle way of controlling and synchronization our sleep with the environment. When sun shines, it emits blue wavelength in it. When it is absorbed by our eyes, it sends a signal through our brain that it is day time. When your brain gets that signal, it suppresses the hormone called Melatonin, due to which we feel alert and active. The lack of sunshine, results in lack of blue light that in turn  increases melatonin.

But if we get the same blue light through artificial light sources like LED TVs, reading lights, Book lights, our mobile phones, then our sleep gets delayed.

It is important to protect yourself in the evenings and nighttime to get a good quality sleep. But if you love to read at night, then make sure that your block the blue light either by using a amber or  warm color light, or wear blue light blocking glasses. Or you can get both of these and be on the safer side.
