It can boost alertness and mood it supports cognitive function and memory and it helps to regulate the body s natural sleep cycle circadian rhythm.
What damage does blue light do to your eyes.
While there s no strong scientific evidence that blue light from digital devices causes damage to your eyes there is a growing concern that blue light can have long term effects on our health.
There are two ways in which one can protect and prevent this damage.
The organization says blue light from digital devices does not lead to eye disease and doesn t even cause eyestrain.
Part 1 blue light is high energy light which when exposed to in large doses can cause damage to the cells in our eyes and skin thinking digital eyestrain and dry skin after using a laptop all day.
The researchers suggest that progressive destruction of light detecting cells in the eyes due to prolonged exposure to blue light could therefore contribute to age related macular degeneration.
Fatigue dry eyes bad lighting or how you sit in front of the computer can cause eyestrain.
As part of the normal aging process the eye s natural lens eventually blocks some short wavelength blue light as well the type of blue light with the highest potential to cause damage to the retina and lead to macular degeneration and vision loss.
Sunlight contains visible and invisible ultraviolet light rays.
Parts of the eye.
Children are a particular concern because their developing eyes absorb more blue light than adults putting them at greater risk of damage.
Retinal which is produced by the eye is triggered by blue light and causes various chemical reactions.
Blue light from computer screens and digital devices can decrease contrast leading to digital eyestrain.
These reactions within the eye can be poisonous to the photoreceptor cell molecules.
This has been seen in experiments on mice.
Blue light is also known to sabotage your sleep schedule because it messes with your circadian rhythm aka your internal clock that tells you when it s time to sleep or be awake.
One fear is that overexposure to blue light could lead to retinal damage as is seen in the development of age related macular degeneration amd.
This light may affect vision and could prematurely age the eyes.
Blue light in and of itself is not all bad.
Blue light and ultraviolet light place oxidative stress on the retinal pigments.
