Too much screen time linked to myopia epidemic among young people

Too much screen time is linked to myopia epidemic among young people. Ask anyone about the benefits of technology and it probably won’t take long for them to come up with a list of examples:
it helps expand your knowledge, connect with new and old friends, and allows you to see things you’ve never seen before.

But what about the downside? Here is the main one:

Increased screen time is hard for your eyes.

Indeed, more and more young people are wearing glasses to correct their nearsightedness. This trend has prompted eye health experts to investigate whether the use of electronic devices such as computers, tablets, and smartphones is causing disease-related vision loss. Take Pauline as an example, although she could easily be David or Jason. She is 10 years old and is a studious, good student. Like any young person her age, she likes to use her tablet for study or entertainment. She works there two hours a day, plus weekends.

However, Pauline can change. She was recently diagnosed with nearsightedness and her ophthalmologist advised her and her parents to limit their use of electronic devices and spend more time playing outdoors.

Pauline is not happy. She thinks it’s not fair.

But his case begs the question:

What is the link between the use of electronic devices and the onset of myopia?

A public health problem
Forty percent of North Americans are nearsighted. The number of cases doubled between 1972 and 2004 and continues to grow at a rate that qualifies the phenomenon as an epidemic.

In Europe, myopia is common in 42.2% of adults aged 25-29, almost twice that of adults aged 55-59.

This shows that there is a real public health problem we are facing – not just a common problem of refractive error in the eye that manifests as blurred vision when looking at long distances.

In fact, severe myopia significantly increases the risk of major eye disorders such as retinal tears (21 times), glaucoma (40 times) or cataracts (6 times).

A nearsighted eye will lengthen. Stretching is proportional to the increase in myopia. The more stretched the eye, the thinner the retina located inside the eye. Symptoms such as fissures, abnormal growth of blood vessels under the retina, and bleeding may be present.

Finally, patients with severe myopia have a more than 50% chance of being completely blind for the rest of their lives, i.e. living with a 60% reduction in vision. This means their eye length exceeds 28mm (normal length is 23mm) or the degree of myopia exceeds six diopters. (Diopter is a unit of measurement used to calculate vision – further from zero indicates impaired vision.) It is important to intervene before this happens to avoid these levels.

(In Canada, legal blindness is defined as visual acuity below 20/200 in the eye that is better with glasses or contact lenses. Therefore, a legally blind person sees 20 times worse than someone with normal vision 바카라사이트.
