What does blue light do to your eyes?

This present era of digital civilisation has made all of us glued to either smartphones, computers, laptops, television, tablets or other digital screen devices. Although, these devices are part and parcel of our lives for good, yet there are drawbacks and risks associated with these smart digital devices. One of the harmful effects carried by these digital devices that go unnoticed is the emission of blue light and the damage it causes. Blue light is the short wavelength from 400 to 450 nanometer of the light spectrum, being visible to human eyes. It is this blue light which makes the sky appears blue.

Harmful effects of blue light on eyes

Our eyes consist of a sensitive lens that is not strong enough to filter out or block blue light at all therefore; it allows blue light to reach upto the retina.  Minimal exposure to blue light is acceptable in the day time to keep us awake, but exposure for extended hours surely rings the alarm bell. Blue light after passing through the eye lens can irreparably damage retinal cells. This blue light slowly and gradually makes us prone to :

Eye strain: staring digital screen continuously leads to fatigue eyes followed by redness, dryness, teary eyes, irritation in eyes.

Digital migraine: a throbbing headache caused due to reduced blood flow in the eye or lack of sleep

Macular degeneration: the centre of the retina deteriorates leading to vision loss  

Not only eyes, unnaturally emitted blue light decreases the secretion of Melatonin hormone in the body after sunset which consequently signals the brain to keeps us awake.  This way circadian rhythm i.e. the natural sleeping and waking pattern of our body’s clock is disturbed due to fluctuation in Melatonin hormone at odd hours.


Well, as an easy measure, blue light can be blocked by applying blue light filter glasses on the digital screen devices. Keeping blue light filter mode or reading mode turned on over smartphones, laptops, computers etc. especially during working hours, can also help in filtering out blue light to a great extent.  We cannot stop using digital devices any day, thus, to handle blue light wisely, it is imperative to wear glasses block blue light when using any of the digital devices.
