If you look around you, you will notice that most people you know probably wear spectacles and prescription lenses. In fact, you will find children as young as 4 years wearing them as well. It almost seems like the norm at this point, and while you will find everyone blaming technology and computer screens for causing this to happen, there are other reasons as well.
Yes, using our screens for long periods of time, especially in the darkness is known to weaken our eyesight, but other factors like genetics also play a role, and interestingly, our diets as well. People who have poor diets are also likely to ruin their eye health, resulting in weak or poor vision. Some researchers noted that children with poor eyesight usually had unhealthy diets as well, and that makes sense. Our entire body essentially runs on nutrients and it is because of the benefits provided by these nutrients that our body is able to grow, and if you deprive your body of those said nutrients, it will end up getting weak.
If you are interested in learning more about what foods you can take for improving your eye health, then you can visit http://www.dietoflife.com/diet-foods-and-eye-health/ for more information on that matter. However, to put things simply, your eyes also require nutrition and important vitamins in order to stay healthy, and if you are unable to provide said nutrients in a sufficient amount, then your eye health will end up suffering. Now, if you already have glasses, you should still work on improving your diet, because your eyesight is still at risk of growing progressively worse, so avoid long exposures to different screens, and try to have a more healthy diet at least for the sake of your eye’s health.
