Half the world will need glasses by 2050 because of screens

New research has shown that by 2050, half the world’s total population could be short-sighted and require corrective glasses.

Currently, thirty-four percent of the world’s population have difficulties with their vision.

New research about digital eye strain

According to the research, published by in the Ophthalmology journal, the reason behind this increase in vision problems is a result of too much time spent looking at screens on devices and not enough time spent outside.

The journal stated that the changes “are widely considered to be driven by environmental factors, principally lifestyle changes resulting from a combination of decreased time outdoors and increased near-work activities,” which is a term that is used for time spent looking at screens.

The research also showed that those who are more likely to be short-sighted come from countries with high incomes, e.g. North America, Europe and specific parts of Asia, as these are countries that are likely to have high amounts of time spent looking at screens.

Digital eye strain

Digital eye strain, also known as computer eye strain, is an increasingly common problem in modern life. More and more of us are spending longer and longer staring at screens and this is having a negative impact on our lives.

The symptoms of digital eye strain can be varied, but they are typically reminiscent of eye fatigue. You can get either extremely dry or watery eyes, and can become sensitive to light after a couple of hours in front of a screen.

Protect yourself from digital eye strain

In modern life there are often few ways that you can reduce your exposure to screens. Many of us require them for work, and many day to day tasks now would be next to impossible to complete without the aid of a computer or phone.

However, there are a few ways that you can reduce the effects of digital eye strain.

You can implement the 20-20-20 rule. This involves spending 20 seconds looking at an object 20 feet away for every 20 minutes spent looking at a screen. Simple and effective, but this can take time to develop into a habit.

Another alternative is to invest in glasses that block harmful blue light from  screens, and effectively reduce the effects of digital eye strain.
