In this era where we use smartphone's for almost everything and most of us work on computer screen all-day. We gotta keep in mind that all these devices emit light and blue light in particular may be very toxic for your 👀.
A lost of research has been done on blue light and it has been concluded that it has a potential to lead to macular degeneration which is one of the leading causes of loss of vision in the United States. The degeneration results due to photoreceptor cell death in the retina. These photoreceptor cells function is to capture Visual images and signal it to the brain .
So , basically blue light causes chemical reaction in the eye which poisonous to these 'photoreceptor' cells and hence rendering them damaged. Since there is no regeneration of these cells it leads to vision loss.

Blue light has a shorter wavelength compared to other lights hence bave more energy. This extra energy may be reason behind the chemical reaction s which leads to degeneration. It is seen that blue light leads to degeneration of photoreceptor cells but it is still not clear how much light can harm "how much". But since the cells dont regenerate we know that the damage done is irreversible.

Over using gadgets may also lead to dry eye's due to reduced blinking rate . Sleep is one of the most important factors for optimal health. Lack of sleep may kead to various diseases. Using devices with screen during the night may trick your brain that its daytime and lead to sleep problems. Blue light from the sun or Laptop reduves your sleep due ro very effective melatonin production.

Blue light is not all bane , blue light therapy devices can be used to improve mood, fatigue , performance etc. Many devices now days have blue light protection where they reduce most of the blue light emited by the screen or device and also blue light protection glasses are available which can used while working on tech gadgets.
Thankyou for reading upto here ! Hope you learn something new ^^ Lemme know your thoughts in the comments.
Stay safe!
You are right! most of the time we are not aware of the damage we are doing to ourselves. This post helps to alert us to be more careful with our eyes when using our mobile or computer, thank you for share this!
Yupp we need to be more cautious, about how much time we spend on screen from now on to avoid vision loss. Thakyou for your response!
Well said
Thankyou!

So damn true that you have
Yes a blue light can really damage someone's eyes
Yesss it's very harmful and takes effect in long-term, Thankyou for your response!
Yeah,I learn something new.we should try to reduce the time we expose our eye to the blue in other to make it last longer
Definitely gotta work on the screen time! Thankyou for your response!
Greetings @the-prithvi I knew about electromagnetic radiation on health, but I did not know the effects of blue light, as well as the chemical processes that it generates in our eyes, very good contribution, congratulations and thanks for sharing.
