Myopia on the rise: The link between devices and eye strain in children


Myopia, or nearsightedness, is a common eye condition that makes it difficult to see distant objects clearly. Myopia is becoming increasingly common, especially in children. Studies show that the prevalence of myopia has doubled in the past 50 years, and it is now estimated to affect over 2 billion people worldwide.


There are a number of factors that contribute to the development of myopia, including genetics, environment, and lifestyle. However, research suggests that the increased use of digital devices is a major risk factor for myopia in children.


When we look at a screen, our eyes have to focus on a close object for a long period of time. This can cause eye strain and lead to changes in the shape of the eyeball. Over time, these changes can lead to myopia.


There is a growing body of evidence to support the link between devices and myopia in children. For example, a recent study found that children who spend more than two hours per day on digital devices are twice as likely to develop myopia as children who spend less than two hours per day on devices.


Another study found that children who use smartphones for more than two hours per day are more likely to have progressive myopia, meaning that their myopia gets worse over time.


The good news is that there are a number of things that parents can do to help protect their children from developing myopia. These include:


Limiting screen time to two hours or less per day


Encouraging children to spend time outdoors


Taking breaks from screens every 20 minutes to look at something distant


Getting regular eye exams


If your child is already myopic, there are a number of treatments available to help slow the progression of their condition. These treatments include special contact lenses and eyeglasses.


What parents can do to protect their children from myopia


Here are some specific tips for parents on how to protect their children from myopia:


Set a good example by limiting your own screen time.


Establish clear rules for screen time use in your home.


Create a screen-free zone in your home, such as the bedroom or dinner table.


Encourage your child to spend time outdoors in natural light.


Make sure your child takes breaks from screens every 20 minutes to look at something distant.


Take your child for regular eye exams.


If you are concerned about your child's risk of myopia, talk to your pediatrician or eye doctor. They can help you develop a plan to protect your child's vision.

chemo

  The chemo cocktail churns, a metallic serpent coiling in my gut, its venom rising, a bitter tide. The sterile air, a canvas for the symphony of beeps, a haunting counterpoint to the hollowness inside. My reflection mocks from the steel embrace of the chair, a gaunt caricature, eyes hollowed, skin the hue of despair. Each breath a labored rasp, a dry leaf skittering on stone, as the serpent writhes, promising oblivion's unknown. Sleep, a fragile escape, crumbles into a twisted dream. A figure cloaked in midnight strides across the barren plains, his scythe a crescent moon, casting an inky sheen on the cracked and thirsty earth, mirroring my ravaged veins. The Grim Reaper, eyes smoldering embers in the gloom, a silent judge, his gaze a pronouncement of impending doom. His skeletal hand reaches, cold and sure, to claim my soul, but a spark of defiance flares, a flicker to regain control. I lunge, a frail wisp against the night's cold embrace, but the figure fades, leaving on...

My wife was only 32 when she died of metastatic breast cancer

Image
It was only 5 years after we found a lump in her breast.  She was a laboratory technologist in the hospital lab at the time and our medical insurance was good.  To give her the best chance, they gave her both chemotherapy and radiation to the area where the tumor had been found after surgery.  Our son was 1 1/2 years old at the time of the diagnosis and spent a lot of time at his grandmother's house during her treatments.  I went with her each time she received chemo and went through her nausea and vomiting with her after each course. In time they tattooed a tiny dot on her breast in order to guide the radiation to the right area and completed the radiation treatments.  She began recovering and within months had returned to her job at the lab. We both raised our son and went about our lives, hopeful. They did tests for tumor markers monthly without apparent return of the cancer.  One day, 5 years from the beginning she felt bad and was hospitalized. The tum...

Magic Carpet Ride

Image
 Let me take you on a magic carpet ride No silken carpet, stitched by hands unknown, But woven moonlight on a phoenix's down. With whispers of magic, we'll ascend the sky, Where stars like diamonds dance and planets sigh. Through emerald valleys, where dragons sleep, And crystal rivers secrets keep. On winds of laughter, past castles untold, With stories blooming, braver than gold. We'll chase shooting stars across the night, Their fiery whispers our guiding light. Past hidden waterfalls, where sirens sing, And wishes take flight on gossamer wing. No jeweled palace, but a moonlit bower, Where fireflies light each fragrant flower. With hearts entwined, beneath the Milky Way, We'll write our own love story, come what may. This magic we create, unseen, unheard, A tapestry woven with every shared word. So let us dance on stardust, wild and free, For the truest magic lies in you and me. With brushes dipped in dreams, we'll paint the sky, Our souls entwined, as colors dan...
