Opticians (ophthalmologists) predict that many people, soon, will come up with various eye problems that can reduce their eyesight.

This is due to the long-term interaction and visibility of the device, especially mobile phones, tablets, laptops and several other electronic devices that contain carbon dioxide in the eyes.

The world is embroiled in a web of electronic media that has redefined human life, trade and media, among others.

There are uncertain reports that most people around the world spend about 80 percent of their day in the field of electronic devices, socializing, working, playing, and engaging in other activities. In each case, they have seized it, despite obstacles we can scarcely imagine. “

It has also been reported that, on average, some adults spend eight to nine hours a day using technology. This is inevitable due to the proliferation of technology, which makes it acceptable to interact and integrate with devices.

There are fears that the figure could grow. Most jobs now require people to be in front of computers for about 35-40 hours a week. While this is great for keeping in touch with people, running a business and getting a job quickly and efficiently, it affects the health of the users.

While the appearance of these devices is unavoidable, experts have suggested that preventive measures should be taken to protect the eyes, whose failure can lead to blindness.

Unfortunately, many people are unaware that gadgets, including mobile phones and computers, carry harmful toxins.

Doctors also noticed that a large number of children were suffering from eye problems, and many religiously used glasses of medicine at an early age.

While some eye problems are congenital, in particular, cataract, glaucoma and myopia, others are due to life and natural events, such as dry eyes and allergies.

Blue light

Blue light comes from phones, tablets, laptops and other gadgets used in everyday life. Unfortunately, they have been found to have adverse effects on eye health.

Studies show that blue light can cause macular degeneration, passing through the baby and cornea into the retina.

Studies have shown that blue light affects the central vision. It kills cell receptors in the retina. It is so different from other cells in the body that at death it cannot be reborn, meaning that any damage done to them is permanent.

Further research showed that blue light can come back with sunlight. This is bad for the eyes. Blue light is more dangerous because it has shorter wavelengths than other types of light, meaning it has more energy. It also inhibits the body’s secretion of melatonin, a chemical needed by the body for sleep.

Doctors’ predictions

Optometrists are concerned with the increasing demand for small spectacles and other functions, due to a variety of factors that were not previously available.

They predict that there will be a significant increase in the number of people who may need to be monitored soon due to the increase in other eye-catching items, especially electronic devices.

An eye specialist at National Hospital, Abuja, who did not want to be named, said: “I am not surprised by the number of visits to the hospital’s optometry department now. we are ready.

“The reason is simple, the world is digital. You can simply view and meet the world online through your mobile phones, laptops, tablets and other gadgets.

“Most people start and end their day online through their various gadgets. Prolonged exposure to these devices is not good for the eyes. Some people do not even bother to get eye protection. I can confidently predict a hospital visit soon as more people will soon be suffering from eye infections. ”

Optometrist Physician, Dr. Aikhulegbe Chicky Chukwurah, advised that blue lights on phones and other devices should be turned on regularly to protect the eyes from blue light, which is visible from eye-catching screens.

However, he also noted that long-term communication or electronic devices can lead to computer vision syndrome (CVS), also known as digital eye strain (DES): The use of computers and digital visuals Symptoms include fatigue of the eyes, dry eye, headache, blurred vision, blurred vision, double vision, itching, red eyes and tears, pain in the neck and shoulders.

“When you look at a computer, your eyes work harder to concentrate because the text on the computer is not as sharp as it appears on print pages. Also digital visuals come with light, which makes the eyes work harder to look better. ”

Dangers of DES

“Harmful things include looking at a digital window every day for at least two hours without interruption, blurred lighting, flashing or illumination on a computer screen, instability when in front of a computer or laptop, improper vision or distance from a computer, which already exists. or visual impairment (long-term vision and astigmatism) with blurred or distorted glasses. “

CVS Disease

“He is recognized by an eye specialist. Doctors diagnose the disease from a medical history and eye examination in detail. They see if any medicine, health, or natural resources are helping the patients. ”


“Treatment for computer vision syndrome first involves changing the computer by placing 20 to 28 inches from the eyes, 10 to 20 degrees tilted backwards, and slightly below eye level. Also, adjust the settings by adding brightness, contrast and font size

“Try to follow 20-20-20 rules, which means that after every 20 minutes of computer use, look at a distance of 20 meters from the computer for about 20 seconds.

In addition, the brightness of the fabric should be reduced by cutting unnecessary electricity. Close windows and curtains, turn down bright lights, add bright computer filters, adjust the position using chairs with appropriate height and good backing, be upright with floor-to-ceiling feet, or lean forward, or move your head up or down to see. computer clearly.

“Artificial tears or ointments help with dry eyes, glasses too. If there is a refractive problem, they are advised to wear appropriate glasses or contact lenses when using a computer or digital device.

“The distance from the computer is not too long or too short, it is a medium distance. For those who wear far and near straightening they need special glasses called extra medium (computer) distance lenses.

“Also, blue filter lenses, photochromic lenses and anti-reflective lenses should be used. It helps to reduce the brightness and magnitude of blue light entering the eyes.

“If one of these symptoms persists, one should go to an eye specialist for an eye examination. Many of these symptoms, if not followed, can cause serious eye problems.”
