How to protect your Eyes from blue light

PROTECT YOUR EYES FROM BLUE LIGHTS

Prolonged exposure to blue light can trigger adverse chemical reactions in the eye's light-sensitive cell, warn scientists. So take precautions before it's too late.

Practically everyone has the habit of checking their phones before sleeping, Although this might seem like an innocuous practice, it has the potential to damage the eyes quite severely due to the powerful blue light emitted from smartphones, televisions, laptops, tablets, and e-readers all transmit blue light,  which is toxic to specialized eye cells, known as photoreceptors, located in the retina and responsible for our vision.

HOW DOES THE DAMAGE HAPPEN

Retinal is produced by our eyes and is provoked by blue light, which leads to a number of chemical reactions, But it turns out that some of these reactions lead to toxic radicals which can permanently damage the photoreceptor cells in our eyes, leading to cell death. Once they are gone, they cannot regenerate.

"The intensity of blue light emitted from digital devices is very less to cause eye damage. However, with rampant use of technology in every individual's lives, prolonged exposure to electronics can lead to "digital strain" to the eyes." points out Dr. Vishal Grover, an ophthalmologist.

WHAT ARE THE PRECAUTIONS.

The answer is definitely not an easy one because the exposure is unavoidable. But simply reducing the screen time or closing your eyes and putting the device away always help. Several tech companies have already made attempts to reduce the risks. Apps like the "Night Shift" and "Blue Light Filter" help in reducing its harmful effects. Always in most of the new phones are some setting like "Reading Mode" and "Turn of Blue Light" are helpful.

According to scientists, blue light also has been implicated as a factor which can suppress the secretion of melatonin, reducing your ability to fall and stay asleep at night, Lack of proper sleep has been linked to coronary artery disease, type 2 diabetes, anxiety, and depression as well as obesity.

"There are reports that link excessive exposure of UV Light with breast and prostate cancer. While there is an association of high dose exposure of blue light with cataract, eye strain, and macular degeneration, link with eye cancer is not yet established," states Dr. Umang Mathur, an ophthalmologist.

WHAT DOCTORS SAY?

Protecting ourselves from the harmful blue light is definitely not easy. But there are ways to tackle it. For instance, the 20-20-20 rules. According to the rule, a person should move away from the electronics screen every 20 minutes. Look at a distance of 20 feet and blink 20 times. This rule helps reduce strain and fatigue in the eyes.
