With the great development that we
are witnessing in our daily life, the use of cell phones has become a necessity
more than a luxury, but the use of these devices may lead to many damages, so
what is the harm of a mobile phone to the eye?
Damage to mobile phone on the eye :
The blue light
is emitted by smart mobile phones and it negatively affects the human eye, the
blue light is emitted naturally from the sun, and it has many benefits
including stimulating memory, increasing attention and alertness, improving mood,
regulating the natural rhythm of sleep, in addition to Its role in supporting
the growth of visual cells, especially in children.
Although cell
phones emit the same type of rays, exposure to blue light and rays from
electrical devices may cause many damage to eyesight, and we mention in the
following the most prominent damages of a mobile phone to the eye:
1- Most of the
rays from cell phones to the retina are absorbed by the lens and the cornea,
which causes damage to the cells of the retina and causes macular degeneration
(macular degeneration) in the long term, causing serious vision problems.
3- Using cell phones for long hours without rest
increases the chance of many vision problems,
such as cataract or cataract,
the appearance of pterygium in the eye,
and the occurrence of cancer in the visual tissues.
4- In the case
of using cell phones, the rate of blinking of the eyes decreases without the
person noticing it, which leads to fatigue and redness of the eyes, blurred
vision, and the occurrence of severe dryness or what is known as dry eye
syndrome.
Damage to blue light on the eyes:
Smartphones and other portable devices
transmit light, and the blue light emitted from cell phones is very toxic;
Because it has a shorter wavelength compared to other colors, and this can lead
to macular degeneration, which may lead to vision loss, and this disease
results due to the death of the photoreceptor cell in the retina, and the
photoreceptor cells capture visual images, And send it to the brain using a
molecule called the retina, and it is important to mention that these cells do
not regenerate when they die, and to reduce the damage of this light, you
should reduce the time of using cell phones, close the eyes for a short period,
or stare at a distance to help relax the eye muscle, and reduce stress.
Phone damage mitigation tips :
After cell
phones and electrical devices of all kinds have become an integral part of
daily life, it has become indispensable to use them, but the damages of a
mobile phone can be mitigated by following the following tips:
Not to use a
mobile phone or any electronic device such as computers and tablets of all
kinds for more than 20 continuous minutes, as it is advised to do any other activity
that does not require the eyes to focus on close objects for at least 20
seconds.
The use of blue
light protection glasses when using a mobile phone or computer, to reduce eye
fatigue resulting from blue light, and these glasses also have a role in
reducing sleep disturbance resulting from the use of cell phones.
Try to keep the
mobile phone away from you while in use, by using the loudspeaker for calls and
not talking on the phone for a long time. You can also use the Hands-free
accessory mode to make calls without using the phone close-up.
Although the
protectors used to protect against the rays of cell phones protect from blue
light, they increase the energy that the phone automatically emits and thus the
rays emitted by it, so their use is no longer recommended in the case of using
phones and smart devices.
Ensure that
children are obligated to a certain period during the day to use phones and
smart devices, and encourage them to go out of the house and engage in physical
activities with their peers.
In the event
that you suffer from redness and dry eyes, it is recommended to use
moisturizing eye drops after consulting a doctor.
Make sure to
see an ophthalmologist periodically to perform the necessary checks to ensure
the safety of your eyesight.
What is age-related macular
degeneration?
Excessive
screen usage and exposure to blue light has been found to accelerate the
development of age-related macular degeneration (AMD). AMD mostly occurs after
the age of 60, but experts believe that, as time goes on and screen usage
increases, this will be brought forwards. In fact, it’s predicted that by 2040,
288 million people will be affected. blue light destroys the eye’s
photoreceptor cells and therefore hinders central vision. Some newer studies,
however, suggest that blue light instead “promotes the growth of poisonous
molecules” in your eyes, causing AMD. This is because it is beamed directly
into your retina, causing much more damage than other less intense forms of
light.
Symptoms of AMD
are usually seen in your central vision in the form of distorted or blurred
objects. As the condition progresses, black spots may appear in your central vision,
blocking your view. Other symptoms can be colours appearing faded,
hallucinations, and straight lines appearing wavy . AMD is one of the world’s leading causes of
blindness, so it’s important to understand how your lifestyle choices – such as
screen use – may affect its development.
