A team from Harvard Medical School compared reading paper books and light-emitting e-readers before sleep.
Original Kindle readers do not emit light so should be fine, say experts.
Experts said people should minimise light-exposure in the evening.
Do e readers interfere with sleep?
A new study has claimed that light-emitting e-readers “negatively affect sleep, circadian timing and next-morning alertness” when used in the evening. The screens of devices such as tablets and smartphones have long been known to emit short-wavelength light, also known as blue light.
Does Kindle Paperwhite light affect sleep?
The Kindle Paperwhite is side lit and not backlit like smartphones. This ensures that light does not directly fall on your eyes but the screen which isn’t much reflective. Technically The light emitted from it is a blue spectrum and affects the proper functioning of melatonin.
Does Kindle have a night mode?
Although the Kindle does not have an official night mode, if you read with a Kindle Fire you can change the display color mode to white on black (white text with a black background), reducing the amount of light from the screen.
Is Kindle light bad for your eyes?
I don’t think a Kindle e-ink reader could hurt your eyes any more than a real book could. However a Fire tablet is a different story. No, but you can adjust the settings to prevent eye strain. You can increase font size and, if you have a Kindle with a light, change the brightness.
