Excessive screen time is changing our eyes faster than we can blink

Published

 on

Pedram Mousavi’s work is all about detail, so his vision must be sharp. The luxury auto detailing studio owner says in addition to looking at glossy reflective paints, he spends hours staring at his computer and phone screens.

That’s why he became concerned when he began experiencing vision problems.

At first, he said, it just felt like he had dust in his eyes.

“There was something wrong with my eyes. They were reddish and dry, dry, dry,” said the 43-year-old Toronto business owner, one of more than 10 million Canadians with evaporative dry eye disease.

Eye health experts say research now links overuse of computer and smartphone screens to several progressive, irreversible eye disorders, such as dry eye disease and myopia, at rates not seen before.

By 2050, 50% of people will have myopia: WHO

“There has been an exponential increase in screen time since the pandemic,” said Dr. Rana Taji, owner and medical director of Toronto Medical Eye Associates. She is one of many eye specialists who have issued online warnings about how screen overuse is changing people’s eyes.

Over time, staring too long at screens can change the structure of the eyeball and lead to atrophy of the glands that keep it moist. Research is now pointing to excessive screen time for the rise in eye disorders, such as dry eye and myopia, which are becoming more common and affect more young people.

In a 2022 Statistics Canada survey, Canadians reported looking at screens an average of about 3.2 hours per day. But Canadian research released in April 2023 shows that occupational and recreational screen time averages among participants were much higher than pre-pandemic levels, with people often reporting six to seven hours per day. Participants in this study reported spending between zero and 12.5 hours per day on screens for recreation alone.

By 2050, more than half of the world’s population is expected to be myopic, meaning one in every two people will be nearsighted, a finding backed by the World Health Organization.

What are myopia and dry eye disease?

Myopia occurs when the eyeball elongates from front to back. This affects its ability to bend light, which enables sharp vision. This elongation increases nearsightedness, making distant objects blurry.

While myopia or nearsightedness has a genetic component, it has been shown to progress faster in people who overuse screens.


Human eyes can also become chronically dry if the meibomian glands — a sebaceous gland that helps create protective tear film — become obstructed or atrophy. Meibomian glands secrete meibum, which is a specialized substance containing lipids that protects the eye surface.

It’s different than the watery tears that flush the eye. Without a healthy tear film, eyes become dry, sensitive to light and irritated. Research has linked staring at digital devices for long periods without proper blinking to degraded gland function, even in some children.

When humans stare at screens, their blink rate decreases. Blinking activates the meibomian glands. If the eye does not blink enough, this can clog the glands and, over time, damage them.

Dr. Vivian Hill, a Calgary-based pediatric ophthalmologist and surgeon who chairs the Council on Advocacy of the Canadian Ophthalmological Society, said it’s critical to give eyes a break and lubricate them by blinking.


“Whenever we’re staring at a screen, our blink rate goes down to about 10 per cent of normal. So that means we’re blinking once instead of 10 times,” she said.

“The eyelids are little windshield wipers that have oil glands in them that basically smooth the oily tears, the moisturizing tears, over the eyeball.”

Hill said when it comes to how long it’s safe to stare at a screen, there’s no magic number.

”No great answer exists on the exact number of hours,” she said. “If your eyes feel dry, take more frequent breaks with blinking.”

And keep screen time to two hours for children between the ages of five and 17, she said.

No screen time in 1st year of life, experts recommend

Dr. Harry Bohnsack, president of the Canadian Association of Optometrists, said research also shows that the more time children spend looking at screens, the more likely they are to develop nearsightedness.

“In that first year of life, children ought not to be spending any time staring at screens,” said Bohnsack, who has a practice in Fredericton.

 

Optometrists see worsening myopia in kids, as screen time increases amid pandemic

 

Eye doctors say they’re seeing the effects of a big increase in childrens’ screen time over the past year. It’s showing up in worsening myopia — or nearsightedness. Philip Lee Shanok has the details.

“We think that it’s the lack of eye movement and refocusing from far too close … interfering with the normal functional development of the child’s eyes.”

Bohnsack said this includes all screens, even television.

“We really want our children to get off the screens, especially at that younger age,” he said.

How screen use affects young eyes

Taji, of Toronto Medical Eye Associates, said she treats children with vision problems made worse by screen use.

“There is an explosion of a faster progression of myopia in children. Just the other day I had a patient who was nine or 10 years old, and we’ve been watching him,” she said. “His prescription has progressed at an alarming rate, faster than the average. We’ve had multiple discussions about reducing screen time and increasing outdoor activity.”

When the eye is forced to stare at something too close, the brain and eye adjust or “accommodate” to increase close-up vision. Over time, the squeezing of muscles can change the shape of or elongate the eyeball. This can cause dramatic changes in eye function, especially in a child’s eye that’s not fully developed, Taji and other specialists said.

Dry eye disease also shows up in children.

Taji said she often sees it present in children as styes — bacterial infections in the glands at the base of eyelashes — that swell and redden. It’s a tell-tale sign of gland dysfunction in children, a condition exacerbated by excessive staring at screens.

Impact of the pandemic on our eyes

When the COVID-19 pandemic arrived, people were cooped up inside — often reliant on screens for work, school and entertainment. But too much screen time harmed vision, Hill said.

She calls the pandemic the “worst” thing for myopia, as rates spiked worldwide. She also said she’s seeing more cases of crossed eyes and double vision.

Slowing the progression of myopia in children is critical, as it puts the eye at risk for issues down the road, from retinal detachment to glaucoma, Hill said.

“I tell it to all the children, even the little ones: Please go outside at recess. Please go outside at lunch. Play. If you’re going to be reading or on screen, make sure you take a break. Make sure that you have some exposure to natural daylight.”

How do we treat these diseases?

Myopia is irreversible, but its progression can be slowed in most cases. It’s usually treated with eyeglasses or contact lenses. There are also corrective surgeries, including corneal laser or intraocular lens implants. Topical drops are often used to slow the progression of childhood nearsightedness.

Meibomian gland atrophy is treated with intense pulsed light therapy, or IPL, or the use of a special needle to probe each gland to clear the 25 or 30 glands of scar tissue or obstructions.

Prevention

  • Limit screen use and take breaks.
  • Go outside.
  • Move the screen to an angle where you are not straining to look up and keeping your eyes open wider.
  • Use lubrication drops with no preservatives, especially adults.
  • Use the 20/20/20 rule: Every 20 minutes take 20 seconds to fully blink 20 times.

Here is how to prepare your online accounts for when you die

Published

 on

 

LONDON (AP) — Most people have accumulated a pile of data — selfies, emails, videos and more — on their social media and digital accounts over their lifetimes. What happens to it when we die?

It’s wise to draft a will spelling out who inherits your physical assets after you’re gone, but don’t forget to take care of your digital estate too. Friends and family might treasure files and posts you’ve left behind, but they could get lost in digital purgatory after you pass away unless you take some simple steps.

Here’s how you can prepare your digital life for your survivors:

Apple

The iPhone maker lets you nominate a “ legacy contact ” who can access your Apple account’s data after you die. The company says it’s a secure way to give trusted people access to photos, files and messages. To set it up you’ll need an Apple device with a fairly recent operating system — iPhones and iPads need iOS or iPadOS 15.2 and MacBooks needs macOS Monterey 12.1.

For iPhones, go to settings, tap Sign-in & Security and then Legacy Contact. You can name one or more people, and they don’t need an Apple ID or device.

You’ll have to share an access key with your contact. It can be a digital version sent electronically, or you can print a copy or save it as a screenshot or PDF.

Take note that there are some types of files you won’t be able to pass on — including digital rights-protected music, movies and passwords stored in Apple’s password manager. Legacy contacts can only access a deceased user’s account for three years before Apple deletes the account.

Google

Google takes a different approach with its Inactive Account Manager, which allows you to share your data with someone if it notices that you’ve stopped using your account.

When setting it up, you need to decide how long Google should wait — from three to 18 months — before considering your account inactive. Once that time is up, Google can notify up to 10 people.

You can write a message informing them you’ve stopped using the account, and, optionally, include a link to download your data. You can choose what types of data they can access — including emails, photos, calendar entries and YouTube videos.

There’s also an option to automatically delete your account after three months of inactivity, so your contacts will have to download any data before that deadline.

Facebook and Instagram

Some social media platforms can preserve accounts for people who have died so that friends and family can honor their memories.

When users of Facebook or Instagram die, parent company Meta says it can memorialize the account if it gets a “valid request” from a friend or family member. Requests can be submitted through an online form.

The social media company strongly recommends Facebook users add a legacy contact to look after their memorial accounts. Legacy contacts can do things like respond to new friend requests and update pinned posts, but they can’t read private messages or remove or alter previous posts. You can only choose one person, who also has to have a Facebook account.

You can also ask Facebook or Instagram to delete a deceased user’s account if you’re a close family member or an executor. You’ll need to send in documents like a death certificate.

TikTok

The video-sharing platform says that if a user has died, people can submit a request to memorialize the account through the settings menu. Go to the Report a Problem section, then Account and profile, then Manage account, where you can report a deceased user.

Once an account has been memorialized, it will be labeled “Remembering.” No one will be able to log into the account, which prevents anyone from editing the profile or using the account to post new content or send messages.

X

It’s not possible to nominate a legacy contact on Elon Musk’s social media site. But family members or an authorized person can submit a request to deactivate a deceased user’s account.

Passwords

Besides the major online services, you’ll probably have dozens if not hundreds of other digital accounts that your survivors might need to access. You could just write all your login credentials down in a notebook and put it somewhere safe. But making a physical copy presents its own vulnerabilities. What if you lose track of it? What if someone finds it?

Instead, consider a password manager that has an emergency access feature. Password managers are digital vaults that you can use to store all your credentials. Some, like Keeper,Bitwarden and NordPass, allow users to nominate one or more trusted contacts who can access their keys in case of an emergency such as a death.

But there are a few catches: Those contacts also need to use the same password manager and you might have to pay for the service.

Pediatric group says doctors should regularly screen kids for reading difficulties

Published

 on

 

The Canadian Paediatric Society says doctors should regularly screen children for reading difficulties and dyslexia, calling low literacy a “serious public health concern” that can increase the risk of other problems including anxiety, low self-esteem and behavioural issues, with lifelong consequences.

New guidance issued Wednesday says family doctors, nurses, pediatricians and other medical professionals who care for school-aged kids are in a unique position to help struggling readers access educational and specialty supports, noting that identifying problems early couldhelp kids sooner — when it’s more effective — as well as reveal other possible learning or developmental issues.

The 10 recommendations include regular screening for kids aged four to seven, especially if they belong to groups at higher risk of low literacy, including newcomers to Canada, racialized Canadians and Indigenous Peoples. The society says this can be done in a two-to-three-minute office-based assessment.

Other tips encourage doctors to look for conditions often seen among poor readers such as attention-deficit hyperactivity disorder; to advocate for early literacy training for pediatric and family medicine residents; to liaise with schools on behalf of families seeking help; and to push provincial and territorial education ministries to integrate evidence-based phonics instruction into curriculums, starting in kindergarten.

Dr. Scott McLeod, one of the authors and chair of the society’s mental health and developmental disabilities committee, said a key goal is to catch kids who may be falling through the cracks and to better connect families to resources, including quicker targeted help from schools.

“Collaboration in this area is so key because we need to move away from the silos of: everything educational must exist within the educational portfolio,” McLeod said in an interview from Calgary, where he is a developmental pediatrician at Alberta Children’s Hospital.

“Reading, yes, it’s education, but it’s also health because we know that literacy impacts health. So I think that a statement like this opens the window to say: Yes, parents can come to their health-care provider to get advice, get recommendations, hopefully start a collaboration with school teachers.”

McLeod noted that pediatricians already look for signs of low literacy in young children by way of a commonly used tool known as the Rourke Baby Record, which offers a checklist of key topics, such as nutrition and developmental benchmarks, to cover in a well-child appointment.

But he said questions about reading could be “a standing item” in checkups and he hoped the society’s statement to medical professionals who care for children “enhances their confidence in being a strong advocate for the child” while spurring partnerships with others involved in a child’s life such as teachers and psychologists.

The guidance said pediatricians also play a key role in detecting and monitoring conditions that often coexist with difficulty reading such as attention-deficit hyperactivity disorder, but McLeod noted that getting such specific diagnoses typically involves a referral to a specialist, during which time a child continues to struggle.

He also acknowledged that some schools can be slow to act without a specific diagnosis from a specialist, and even then a child may end up on a wait list for school interventions.

“Evidence-based reading instruction shouldn’t have to wait for some of that access to specialized assessments to occur,” he said.

“My hope is that (by) having an existing statement or document written by the Canadian Paediatric Society … we’re able to skip a few steps or have some of the early interventions present,” he said.

McLeod added that obtaining specific assessments from medical specialists is “definitely beneficial and advantageous” to know where a child is at, “but having that sort of clear, thorough assessment shouldn’t be a barrier to intervention starting.”

McLeod said the society was partly spurred to act by 2022’s “Right to Read Inquiry Report” from the Ontario Human Rights Commission, which made 157 recommendations to address inequities related to reading instruction in that province.

He called the new guidelines “a big reminder” to pediatric providers, family doctors, school teachers and psychologists of the importance of literacy.

“Early identification of reading difficulty can truly change the trajectory of a child’s life.”
