Sophisticated technology helps people to do work, one of them is a cellphone. Before the cellphone is created, people will exchange information by mail. Unlike today, just flicking your fingers on a cellphone screen, our message has been conveyed to others.
It's not strange if there are now many people, including you spending time struggling with cellphones, laptops, or other digital devices to get information or just seek entertainment. Even though it makes it easier for you to get information, all these digital devices actually have an adverse effect on your health.
Research says that blue rays (blue light) that radiates from smartphonelaptops, and other digital devices can damage the sense of sight and cause blindness. To be clearer, consider the following review.
Why is blue light the cause of blindness?
A study conducted by the University of Toledo in the United States revealed that exposure to blue light that is too long can trigger photoreceptor cells (light sensitive) in the eye to produce toxic molecules that harm the eyes.
This molecule, called a retinal, initially functions to help photoreceptor cells to capture light and transmit signals to the brain. However, the presence of blue light can turn retinal into a dangerous molecule for photoreceptor cells because it can dissolve photoreceptor cell membranes.
Blue light has shorter waves and more energy than other colors. When these rays enter the eye, the lens and retina cannot block or reflect so that they affect and damage the photoseptor cells.
"Dead photoreceptor cells cannot regenerate and will be damaged," said Dr. Kasun Ratnayake, a member of research at the University of Toledo, was quoted as saying by the Huffington Post.
Damage to photoreceptor cells can cause macular degeneration (macular degeneration), which is the most common cause of blindness in people aged 50 years or more. A small macula or organ near the center of the retina that sharpens the object seen by the eye. This macula can be damaged as you age. However, it will happen sooner one of them because of the blue light fromsmartphone, laptops, or other digital devices.
Macular degeneration does not cause a total blind person, it can be in one eye. However, vision will become blurred or not as bright as normal vision. This condition can interfere with simple daily activities, such as recognizing someone's face, reading, driving, or writing.
How do you reduce blue ray radiation in the eye?
Prevention is better than cure, right? In order for you to reduce the risk of macular degeneration due to exposure to blue light from cellphones, laptops and other digital devices, you must reduce the use of these objects.
For example, avoid playing cellphones before going to bed or at leisure. If you usually read e-book or news via cellphone, you can switch to printed newspapers or books.
Dr. Ajith Karunarathne, assistant lecturer at the Kimian and Biochemistry Faculty at the University of Toledo suggested protecting the eyes from blue lightby wearing special sunglasses, which are designed to filter UV and blue light.
In addition to reducing exposure to blue light, macular degeneration can be slowed down by implementing a healthy lifestyle. Try to quit smoking, eat nutritious foods, and exercise regularly.
