Your smartphone may make you go blind soon!
Today, smartphones are an inevitable part of our life. The average person spends at least a few hours on the smartphone every day on activities such as reading, shopping and social media. The smartphone brings the world into your hands but too much exposure to the blue light it emits can hasten blindness
A study from University of Toledo throws up some alarming facts. It states that regular exposure to the blue light from smartphones, laptops, tablets and the sun "transforms vital molecules in the eye's retina into cell killers." The problem is that the cornea and the lens of the eyes can neither block the blue light emitted nor reflect it.
How does blue light affect the eyes?
To understand how this happens, all of us have a molecule in our eyes known as alpha tocopherol. This is a natural antioxidant and its function is to prevent photoreceptor cells from dying. However, as we age, our immune system becomes weaker and is no longer capable of defending itself against the toxic retinal attack. This is when the damage starts.
This apart constant exposure to blue light can create other complications as well. It can cause macular degeneration which is a dangerous eye disease which will lead to blindness in the 50s or 60s. There is no known cure for this.
What you can do to protect yourself
To combat the negative effects of blue light Apple, Amazon and Google have introduced blue light filters which will help bring down users' exposure. For instance, Apple's iOS and MacOS have a Night Shift mode that you can use and adjust the display to warmer colors. Researchers say that wearing sunglasses can help in filtering UV and blue light. They also recommend skipping the usage of digital devices in the dark. Despite these precautions, there is no guarantee that the impact is fully cut down. Limit your screen hours, that’s the best way out.
