Imbunatatirea vederii in mod natural
Focusing your vision on a particular object one after the other may cause more strain on the eye than any other thing. It is better to have your sight moving from one object to another than having it fixed on an object. Making sure your sight move from one end to another causes them to relax even more.
Another tip on how to see better without glasses is through is to have our sight focused on a centralized area of any picture we are looking at. This is quite contrary to the method where some people just have their sights focused on a wider picture.
