Today, more than half of the people in the world will have trouble seeing things far away by 2050, this is a big deal. It is because of something called myopia, or short-sightedness. It affects lots of people, from young to old, and it is getting worse.

The reasons for this are many. First, more people are living in cities. This change in lifestyle has a big impact on eye health and the number of people with myopia is increasing. This is especially true for those with high myopia, which can lead to serious eye problems.  Scientists have seen that the age when people first get myopia is getting younger. This is a problem because it means more people will have myopia for a longer time. And as myopia gets worse, the risk of serious eye problems goes up.

The landscape of the world is changing, and so are the reasons for myopia. Urbanisation is one of the causes of myopia and climate change is causing a major change in how we live.  People spend more time indoors, and less time outside. This change in lifestyle might make myopia worse. People are also living longer, which means more people will have myopia for a longer time.

But it is not all bad news. We can do something about it. If we understand more about myopia and how to stop it, we can help people see better for longer.  Lots of people are working on this. Doctors, scientists, and even companies are trying to find ways to stop myopia from getting worse. Some of these ways include changes in lifestyle, new treatments, and even special glasses.

The good news is that there are things people can do to help.  For example, spending more time outside can help. This is because natural light helps the eyes. Also, limiting screen time can help. This is because staring at screens for too long can make myopia worse. And finally, eating a healthy diet can help. This is because certain foods have nutrients that are good for the eyes.

But there is still a lot we don't know. There are still questions about myopia that we need to answer. For example, why does it get worse over time? And what can we do to stop it? The answers to these questions could help us find new ways to treat myopia and prevent it from getting worse. So, we need to keep learning more about myopia and how to stop it.
