As with the new age of population becoming adoptive using such devices at a young age for longer hours are becoming victims of CVS at the later stage of their life and now young people are also facing such problems.
Actually, all such digital devices emit blue light which causes the eyes to refract, resulting in surrounding objects going in and out of focus.
And compared to printed text, images on a screen are comprised of thousands of tiny spots, which puts additional stress on the eyes causing CVS like health problems. So, let’s find out more about this disease and how to prevent or cure computer vision syndrome.

It is obvious that reduce your screen time on such digital devices to avoid CVS, otherwise, excessive use of digital devices can permanently damage your eyes. But owing to studying needs, bounded working hours and gadgets addiction it becomes difficult to reduce the screen viewing time, so you can follow few rules to prevent CVS syndrome.
#1 Reduce the Screen Glare Level
You can change the lighting around you to reduce the effect on your computer screen. If light from a nearby window casts a glare, move your monitor and close the shades. You can also have a dimmer switch for the overhead fixtures if they’re too bright, or buy a desk lamp with a moveable shade that casts light evenly over your desk.

5 Things You Don’t Know About Coronavirus: New Research & Studies
Coronavirus or COVID-19, became one of the worst pandemics of the century, infected millions and killed tens of thousands of people globally. The virus is deadly, as there is no vaccine developed yet and it is a very highly contagious disease.
Declared as a pandemic and people know lots of things about this deadly virus, like its symptoms, how it spread, what are precautions you need to take to keep yourself protected, and what are the possible remedies and treatments, etc.
But since this virus has been found, it has mutated itself and now there are different symptoms and new things are caming out by various research and studies. So, you need to read what you don’t know about COVID-19 and be aware of this deadly virus.
Five Things You Still Don’t Know About COVID-19
#1 Men are Dying More Compared to Women
As per the report published in Aljazeera, men are dying more compared to their women. In China, 2.8 percent of men who caught the virus had died, compared with 1.7 percent of women who contracted it. While in Italy, where the death rate is currently 7.2 percent for men and 4.1 percent for women.
Likewise, South Korea, where extensive testing was carried out, despite showing that the proportion of women who tested positive for the virus was higher than that of men, about 54 percent of the reported deaths were still among men.
Similarly, in other countries, men are more getting infected and also dying higher compared to their female counterparts. And as per the doctors and medical experts, the main reason behind this is, unhealthy lifestyle, excessive smoking or drinking habits, week immune system, hormonal differences and extra X chromosome in women compare to men.
#2 Many Patients are Losing their Sense of Smell
As per the research and new studies, patients suffering from coronavirus infection are losing their sense of smell. Though, as per the British Rhinological Society, post-viral anosmia is one of the leading causes of smell loss in adults, accounting for up to 40% of cases.
And in a few countries, at least 61 percent reported reduced or lost sense of smell, that the mean onset for reduction or loss in the sense of smell was 3.4 days. And in many countries cases, 73% patients lost their sense of smell prior to coronavirus diagnosis.
#3 Smokers, Diabetics, Hypertensives Can Suffer Strokes
As per the new studies and research on COVID-19, people suffering from coronavirus infection and having chronic diabetes, hypertension, smoking or bad health conditions can also suffer from unusual strokes or even heart attacks with deadly consequences.
Covid-19 infection presenting with cerebrovascular accident (stroke) up to 5 to 6 percent, from different studies. And, as per the studies in US, certain young persons have also presented for the first time with stroke due to COVID-19.
#4 COVID-19 in Semen and Can be Sexually Transmitted
Coronavirus is reaching everywhere. As per the recent studies in China, Coronavirus was found in the semen of recovering and acute male COVID-19 patients. Though it remains unknown, according to the CDC, whether the disease can be transmitted sexually.
In the study, originally published on JAMA Network Open and conducted in Shangqiu, China, six patients—15.8%—of 38 COVID-19-positive males had the virus in their semen. And four of those men with COVID-19 in their semen were at the acute stage of infection, while the other two had already recovered.
Though, the research neither confirms nor denies whether the virus can be sexually transmitted or not. As researchers did not follow up with the participants to determine the duration of coronavirus in their semen and whether the men had spread it to their sexual partners or due to any other sources of transmission.
#5 There are 10 Different Types of Coronavirus
Seems very amazing to listen, but you are reading correctly. Yes, coronavirus has mutated itself into different forms and now 10 different types of COVID-19 virus are infecting people globally also making it difficult for medical science to research and develop the right vaccine or medicine for the treatments for every virus.
As per the research from the 3,600 coronaviruses sample collected from 55 countries from December 2019 to April 6, 2020, for their study coronavirus had evolved into multiple types during its initial spread in China and the rest of the world.
Currently, there are 11 types of coronaviruses that are classified into O, A2, A2a, A3, B, B1, O, and so on, including type O which is the ‘ancestral type’ that was first originated from its epicenter in the city of Wuhan, China.
Why Young People are also Dying Because of Coronavirus: 4 Reasons
Coronavirus or COVID-19 has infected all the age groups of people globally, and its true old age people are mainly and easily getting infected and die due to this infection. But do you know many young people are also dying because of this disease?
And recently researchers have identified reasons why young who are fit and healthy could be dying of the new coronavirus COVID-19. Though, mostly aged people are dying, but it also a true, number of younger people – with no known health problems – have died in the UK or other nations after testing positive for the disease.
Dr. Sanjay Gupta, a neurosurgeon and chief medical correspondent for CNN, wrote in his article, all about the reasons behind the death of young people due to coronavirus. So let’s find out what Dr. Gupta wrote and find out the reasons.
4 Reasons Young People Dying Due to COVID-19
#1 Variations in the Genetic Factors
Dr. Gupta said, “One possibility is a gene variation in the ACE2 gene. ACE2 is an enzyme that attaches to the outer surface of cells in the lungs, as well as the heart.” Coronavirus uses such enzymes to enter airway cells and finally into the lungs.
Scientists studying are analyzing the DNA of patients who had serious cases of COVID-19 and no underlying health issues such as diabetes or heart or lung disease, and comparing it with the DNA of those with mild or no pre-existing disease at all.
#2 Depletion of Vital Fluid in the Lungs
As per Dr. Gupta – Another possible factor is that pulmonary surfactant – a fluid secreted by the cells of the tiny air sacs in the lungs – becomes depleted in COVID-19 patients.
This fluid helps the lungs to expand and contract normally, but when the supply is depleted that function is disrupted, the air sacs can collapse and it becomes much harder to breathe for the patients who then supported with ventilators.
Moreover, Dr. Gupta also wrote, if you think of your lungs as a sponge, surfactant would be the detergent which would make them soft and pliable. Without surfactant, however, your lung becomes stiff and hard to squeeze making difficult for patents to struggle to breathe even when they are put on the ventilator.
#3 Highly Sensitive Immune System
In the study, researchers are also looking into the human immune system and how it responds to viruses and bacteria. As it is very much possible that a healthy immune system could lead to severe problems among young people.
The third reason Dr. Gupta wrote: “In some young, healthy people, a very reactive immune system could lead to a massive inflammatory storm that could overwhelm the lungs and other organs. In those cases, it is not an aged or weakened immune system that is the problem – it is one that works too well.”
#4 Negligence in Taking the Precautions
The fourth and last reason, there is a possibility some young people thinking they are healthy and invincible, and therefore taking fewer precautions or ignoring social distancing rules to prevent themselves from catching coronavirus.
Those people “have been exposed to much larger viral loads from the environment or suffering from flu, Dr. Gupta added. In the UK, the most seriously affected patients have been the elderly and vulnerable, according to Government statistics.
In its most recent update, on March 31, the Office for National Statistics wrote: “The vast majority of deaths involving COVID-19 have been among people aged 65 years and over (100 out of 108), with almost half (45) of these occurring in the over-85 age group.”
In US 29% Patients are 20–44 years
In the US, as of March 16, a total of 4,226 COVID-19 cases had been reported, with reports increasing to 500 or more cases per day beginning March 14.
Among 2,449 patients with known age, 6% were aged ≥85, 25% were aged 65–84 years, 18% each were aged 55–64 years and 45–54 years, and 29% were aged 20–44 years. Only 5% of cases occurred in persons aged 0–19 years.
