Staring at the sky naturally cures myopia, the study says


At least one person in your group of friendsis sure to wear prescription glasses.You might actually wear them yourself!Among the most common problems that affectyour vision is nearsightedness, meaning that you can't see objects that are far away.This happens when your eye grows too much.Specialists say that we're in the midst ofa worldwide epidemic, because the number of people who suffer from this problem has doubledwithin the last 50 years.Genetics are normally considered to be themain cause of the appearance of nearsightedness,but a study published in the medical newspaper“The Lancet” says that there may be anothercause—one that is easier to prevent: sunlight.

This study observed the relationship betweentime spent in the sun and outdoor activities and the appearance of nearsightedness.´For example, the children in East Asia normallyspend more time inside with very little sunlight,and almost 90% of them suffer from nearsightedness.According to researchers, sunlight stimulatesthe release of dopamine directly into the eyes.This neurotransmitter appears to prevent oureyes from growing too much.Another explanation presented in a study performedat Queensland University in Australia is thatsunlight somehow nurtures our eyes.Sunlight also stimulates the production ofvitamin D, which is responsible for our brain and immune system's health, and regulatesour eye health.It might also be due to color.Green and blue light waves tend to focus onthe front of the retina, while red light hitsthe back part.When we're indoors with artificial illumination,the light's color pattern may be altered,and it could confuse the mechanisms that controlour eyes.Whatever the reason, sunlight, under the correctcircumstances, is beneficial not only for our physical health, but also our mental health.

It can even help improve problems such asdepression.And, on top of this, it might help you nothave to wear glasses anymore...
