COVID lockdowns led to spike in kids’ vision problems, 1 in 3 now nearsighted, study finds
As many as 30% of children and teens across the world were nearsighted in 2023, a new study has revealed.
Diagnoses of nearsightedness (myopia) are expected to worsen over the next two decades, according to the findings, which were published in the British Journal of Ophthalmology.
By 2050, nearly 740 million young individuals worldwide are expected to have the condition, lead study author Dr. Yajun Chen, a professor at Sun Yat-sen University in China, told Fox News Digital.

“The study also highlights significant disparities in myopia rates across different regions, suggesting that factors such as gender, ethnicity and culture play a crucial role,” he said.
“Understanding these variations is crucial for tailoring prevention and intervention strategies to specific at-risk populations.”

In the study, researchers analyzed 276 studies that included more than 5.4 million participants from 50 countries across all six continents.
Rates of nearsightedness were highest in East Asia (35.22%), in urban areas (28.55%), among females (33.57%), among adolescents (47%) and among high school students (45.71%), the study found.

Myopia can progress rapidly during critical growth periods, particularly in children and adolescents, Chen noted.

“During the pandemic, many countries implemented nationwide lockdowns to curb the spread of the virus,” he said.
“Prolonged indoor living reduced outdoor activity for children and adolescents while increasing screen time, potentially exacerbating the ocular burden on this population and worsening the myopia crisis.”

Dr. Marc Siegel, senior medical analyst for Fox News and clinical professor of medicine at NYU Langone Medical Center, was not involved in the study but commented on the findings.
“Diet may play a role, but I think the greatest reason for the increase, especially coming out of the pandemic, is due to lockdowns and being indoors more,” he told Fox News Digital.
“Untreated myopia can lead to more severe vision problems later in life.”
With increased screen time, kids and teens have fewer opportunities for the eye muscles to have to adapt, Siegel said.
“For example, going back and forth from looking close to looking far, and accommodating to light by going from indoors to outdoors, and talking to people in person — all of those exercise the small eye muscles that keep you from getting nearsighted,” he added.
Warnings of long-term effects
Dr. Jesse Willingham, an optometrist at Brighter Outlook Vision in North Charleston, South Carolina, warned that unaddressed vision problems can have several significant consequences for children, including academic problems, social and emotional struggles, behavioral issues and long-term eye health issues.

“We all understand that being able to see clearly is important for school, but there are many different visual skills we need for learning,” Willingham, who was not involved in the study, told Fox News Digital.
“Nearsightedness is the most common developmental vision problem, but early vision problems can start with tracking difficulties, poor ability to adapt the focus of the eyes or use the two eyes as a team, or other functional problems that arise from too much stress on the visual system at an early age,” he added.
Study limitations
The study did have some limitations, Chen acknowledged.
“The major limitation of the included studies is the disparity in the designs and methods utilized,” he said.

“The quality of included epidemiologic studies varied significantly within and among the reviews, ranging from high to low risk of bias.”
There is also a possibility of “uneven distribution of data” among countries within any given continent, Chen said.
“As a result, our reported findings might be biased because they were mainly influenced by data from a limited number of countries.”
Studies included in the analysis also varied in terms of criteria and procedures for assessing nearsightedness, Chen noted.
Bringing solutions into view
Creating a supportive environment at home and in schools can encourage children to adopt healthy habits that protect their vision, the researchers said.

Experts offered the following interventions to help reduce the prevalence of myopia among youth.
1. Promote outdoor activities
Families should prioritize outdoor playtime, Chen recommended.
“Schools can organize outdoor activities and encourage sports, creating a culture that values physical engagement and natural light exposure,” he said.
2. Manage screen time
For very young children who haven’t started school yet, Willingham recommends only allowing screen time when video-chatting with friends and family.

“For school-aged children, matching screen time one-to-one with outdoor time and limiting screen sessions to no more than 20 minutes at a time are good rules of thumb,” he told Fox News Digital.
“Also make sure screen time is done ergonomically, with screens held at least 12 inches away and done while maintaining good posture.”
3. Schedule regular eye exams

“Early detection and intervention is crucial, as untreated myopia can lead to more severe vision problems later in life,” he said.
“It’s also beneficial to stay informed about new treatments and technologies aimed at slowing myopia progression, such as specialized contact lenses and eye drops.”
It’s important to choose an eye care provider who understands visual development, according to Willingham.

“Developmental optometrists have more training and experience in this area, and are typically affiliated with OVDRA, the Optometric Vision Development and Rehabilitation Association,” he said.
“If your child is at high risk of developing nearsightedness or is already nearsighted, consider finding a myopia management specialist through organizations like TreeHouse Eyes.”
4. Participate in community initiatives
Engaging with community programs aimed at preventing myopia, such as vision screening events or educational outreach, can help reduce the prevalence, according to Chen.
“Prolonged indoor living reduced outdoor activity for children and adolescents while increasing screen time, potentially exacerbating the ocular burden on this population and worsening the myopia crisis,” one eye doctor said. (iStock)
Integrating vision education into school curricula and supporting public health campaigns focused on myopia prevention can also be effective, he added.
“By taking these proactive steps, everyone can contribute to reducing the prevalence of myopia and promoting healthier vision for children and adolescents,” Chen said.
Over the two and a half years following the 2022 rollout of the 988 national suicide prevention hotline, the rate of suicides among young people in the United States dropped 11 percent below projections, decreasing most sharply in states with a higher volume of answered 988 calls, a new study has found.
The findings, published today as a research letter in JAMA, compared suicide deaths from July 2022 to December 2024 with sophisticated mathematical projections that were based on historical trends. This yielded good news, with 4,372 fewer suicides of adolescents and young adults, ages 15 to 34, than had been projected.
To ensure that the decline was related to the use of the hotline, researchers at Harvard Medical School teased out the trends in states with high and low usage of the hotline. The findings were striking: The 10 states with the largest increases in 988 calls experienced an 18.2 percent reduction in observed suicides compared with expected suicides; in the 10 states with the lowest uptake, the reduction was smaller, 10.6 percent.
The results suggest that the government’s investment in the 988 rollout has translated into “a measurable reduction of deaths,” said Dr. Vishal Patel, a resident physician at Brigham and Women’s Hospital and one of the authors of the study.
“What our study has added,” he said, “is evidence for the deeper benefit of the program, and that is, that at the population level, among young people at least, suicide mortality is lower than it would have been without the program.”
Tips for Parents to Help Their Struggling Teens
Are you concerned for your teen? If you worry that your teen might be experiencing depression or suicidal thoughts, there are a few things you can do to help. Dr. Christine Moutier, the chief medical officer of the American Foundation for Suicide Prevention, suggests these steps:
He added, “The implication of that is that sustained funding for this program matters.”
The United States rolled out the three-digit hotline with bipartisan support in July 2022, replacing a 10-digit hotline number, and augmented it with a $1.5 billion investment in crisis center capacity. Since its inception, the service has fielded more than 25 million contacts, according to the Department of Health and Human Services. The agency has asked Congress for $534.6 million to fund the program for 2027.
Last summer, the Trump administration terminated one element of the hotline, the Press 3 option for L.G.B.T.Q.+ callers. The Substance Abuse and Mental Health Services Administration said that the Press 3 option was being discontinued because it had exhausted its funding from Congress and that the hotline would “focus on serving all help seekers.”
But advocacy groups and policymakers protested the decision, and in testimony before the Senate on Tuesday, the health secretary, Robert F. Kennedy Jr., said his agency was planning to restore the Press 3 option.
Dr. Patel said his group had become curious about measuring the program’s effectiveness after Press 3 was eliminated. While call volume and satisfaction surveys suggested that 988 was succeeding, he said, the harder question was, “Did the creation of this 988 program, the transition from the old hotline to this hotline, actually move the needle on suicide mortality?”
Experts said it was difficult to tease out the beneficial effect of 988 from other things that changed in 2022, the year that the new hotline was created. Around that time, suicide prevention programs were being introduced in schools, in faith communities and on social media, but more important, the pandemic was ending.
“We were finally out of this crazy time, and there was a sense of optimism and hope,” said Jonathan B. Singer, a professor of social work at Loyola University Chicago and a co-author of “Suicide in Schools.” He called the downward trend in youth suicides “encouraging, but it is tempered by the fact that we don’t have a good explanation as to why.”
The authors acknowledged that their findings could not account for the influence of social and economic changes, changes in mental health services or public awareness about services.
But they did make comparisons to exclude other possible explanations. The authors looked for similar effects among American adults over 65, who are less likely to use the hotline. In that group, there was a reduction in suicides that exceeded expectations, but it was smaller, at just 4.5 percent.
To ensure the decline in suicides did not reflect a general improvement in young-adult mortality, the researchers tracked cancer deaths, and found there was no change. They also looked at the rates of suicide among young people in England, where no change had been made to the national crisis line in that time period; they found no reduction in youth suicides there.
Hannah Wesolowski, chief advocacy officer for the National Alliance on Mental Illness, said she was persuaded that the hotline had contributed to the improvement in suicide rates, in part because it did not appear among English youths or in older Americans.
“To me, that really helps hone in that this might really be the differentiator,” she said. “We are seeing potentially a pretty significant decline in suicides among young people. For public policy, this is strong evidence to double down on that we are doing.”
Emily Hilliard, a senior press secretary at the Department of Health and Human Services, said H.H.S. and SAMHSA are “committed to ensuring that all Americans have access” the 988 line, which she said “clearly provides lifesaving support, helping millions of people every year.”

A highly contagious digestive virus is surging across the U.S., experts warn.
Rotavirus, a double-stranded RNA virus, causes acute gastroenteritis — inflammation of the stomach and intestines — which can lead to severe diarrhea, vomiting, fever and stomach pain.
The virus primarily affects infants and young children, but there have also been outbreaks in elderly populations, such as nursing homes.
AT LEAST 46 CHILDREN DEAD AMID MEASLES OUTBREAK AS VIRUS SPREADS GLOBALLY
Data from the Centers for Disease Control and Prevention shows that in the week ending April 4, out of 2,329 rotavirus tests, 7.3% were positive for the infection. Last year’s highest infection rate was 6.77% as of the week ending April 19.

“We’re seeing a lot of rotavirus in the wastewater right now,” Dr. Marc Siegel, Fox News senior medical analyst, confirmed to Fox News Digital. “Testing for rotavirus is way down, but the percentage of positive tests is up.”
While the virus typically peaks in the spring, it is not currently slowing down, he noted.
Why cases may be rising
Patricia Pinto-Garcia, M.D., a medical editor at GoodRx who is based in California, said there are several possible reasons for the rotavirus spike.
“Vaccine rates are down overall among young children, as they decreased during COVID,” she told Fox News Digital. “This means there’s a growing number of infants and young children who are vulnerable to infection.”
The rotavirus vaccine series must be completed by the time a child is 8 months old, she noted.
HEALTH ALERT ISSUED FOR DENGUE OUTBREAKS SPREADING IN TRAVEL HOTSPOTS
As a result of the declining vaccinations, herd immunity isn’t protecting vulnerable children, according to Pinto-Garcia. “Children who haven’t finished the vaccine series yet, are too young to get vaccinated, or can’t get the vaccine due to medical illness are more likely to get exposed to the illness because other children aren’t vaccinated,” she said.
Siegel noted that before the vaccine became available, rotavirus resulted in 55,000 to 70,000 in the U.S. per year.
“Vaccine rates are down overall among young children, as they decreased during COVID,” a doctor told Fox News Digital. “This means there’s a growing number of infants and young children who are vulnerable to infection.” (iStock)
“I am concerned that the vaccination rate has been declining over the past seven years and is continuing to decline in the current climate of vaccine skepticism,” he said.
Surveillance methods are also much better than they used to be, Pinto-Garcia noted, which means public health experts are able to pick up and track cases better than ever before.

“But we see that rotavirus-related healthcare visits are also up, so improved detection is not the only reason we are seeing this spike,” she said.
The COVID pandemic also disrupted the pattern of infections, according to Pinto-Garcia, so it’s “tricky” to compare the current levels against older cycles.
“It’s possible that what we are seeing is still some post-pandemic rebound, but it’s unlikely that this year’s pattern is fully explained by just this factor,” she added.
Transmission and risk
Dr. Zachary Hoy, a pediatric infectious disease specialist at Pediatrix Medical Group based in Nashville, Tennessee, often sees young patients with rotavirus.
“Rotavirus is spread via the fecal-oral route, meaning that a person comes into contact with virus droplets from contact with other children or adults, or from contact with objects such as toys that have been contaminated with the virus from someone who is sick,” he told Fox News Digital. “This can lead to outbreaks, especially at schools where many young children share the same toys.”
“It’s possible that what we are seeing is still some post-pandemic rebound, but it’s unlikely that this year’s pattern is fully explained by just this factor.”
Rotavirus is associated with many dehydration cases in the hospital due to the degree of diarrhea, according to Hoy.
In some severe cases, the virus can lead to seizures due to electrolyte imbalances from dehydration and loss of electrolytes in the stool.

“Younger children do not have the reserves that older children and adults have, so they can become more dehydrated quicker and develop more severe electrolyte imbalances, leading to more severe infections,” Hoy said.
“Patients with problems with their immune systems or on medications that can decrease their immune systems can have more severe and prolonged infections, too.”
Treatment and care
Because rotavirus is a viral infection, antibiotics are not effective against it. There is no specific antiviral treatment for the condition, with doctors typically recommending supportive care.
“The mainstay of treatment is hospitalization for rehydration via intravenous (IV) fluids,” Hoy told Fox News Digital. “Sometimes it can take up to two to three days of IV fluids to help get patients rehydrated.”

Blood draws are often necessary to evaluate patients’ electrolyte levels, such as sodium, potassium, calcium and magnesium, according to the doctor.
“If these electrolyte levels are significantly low, sometimes patients need special IV solutions or individual electrolyte medications,” he added.

Dr. Daniel Park, medical director of the Pediatric Emergency Department at UNC Health in Chapel Hill, North Carolina, noted that most children recover with supportive care, but parents should seek medical attention if a child shows signs of dehydration. Those include decreased urination, lethargy or inability to keep fluids down.
“While rare, rotavirus can be life-threatening in vulnerable populations, especially very young infants or children with underlying medical conditions,” Park told Fox News Digital.

Prevention strategies
Given the lack of antiviral medications for rotavirus, doctors emphasize the importance of prevention, primarily the vaccine.
There are two rotavirus vaccines – Rotateq (a three-dose series) and Rotarix (a two-dose series). They are given starting at age 2 months as oral drops, not injections, according to Hoy.

“It’s important to get the rotavirus vaccines on schedule, because these younger infants are at greatest risk if they get rotavirus,” he advised.
Other recommended prevention methods include handwashing with soap and water.
Every day we’re faced with a zillion small choices: Go to sleep early, or watch one more episode of that Netflix drama. Call an old friend to catch up, or cruise social media. Of course, no single action will guarantee a long, healthy life or doom you to an early grave. But those little daily decisions do add up, and over the long term they can make a difference when it comes to both your longevity and your health span, the amount of life spent in relatively good health.
Scroll through this theoretical “day in the life” and select the option that best fits your typical day. Not every situation will apply perfectly, but think about which choice you’d be most likely to make. This isn’t a formal scientific assessment. The goal here isn’t to assign you a “good” or “bad” score, but to help you understand the central factors that shape the way we age and how long we live.
