It is believed that to avoid developing or worsening myopia, we must rest your eyes every 30-40 minutes. The general advice is to look out of the window or take a break outside.Does this really help?

Maybe it won't cure myopia but it will definitely give your eyes the well deserved rest they need, especially after a long day of staring at computers etc. Personally, I practice something similar, I would look out into the distance after every hour and I don't know if it helps to improve my eyesight but it sure does offer much needed relief.
