# 20/20 rule of eyes # Due to access use of gadgets, our coming generation are losing their eye sights. Actually, mobile screens don't hamper our eyes but the way we see them will effect much. Before, in our times this problem was seen with those who used to study much. When we continuely focus on objects that are some centimeters away, our eyes gets habits of seeing at that distance and we go on loosing our long sight and thus we get into shortsightness. And there is some precautions for this and it is 20/20 startegy. It says, if you see something continuously you must break twenty second and at that time one should focus on far away distant things. Focus can be done to anything. So, regardless of our age we must always be aware of 20-20 strategy. Thank you, Lawa1988
