Health habits do not divide the age, if you have some good health habits, you will have a good body. Even if you're an "old people", the good habits should also be developed.
I list all these health habits in the order from head to foot. Avoiding so much content that you will forget it soon, so I just list one point when I update every time.
NO.1 The Hygiene Of Using Eyes.
Looking at green, setting a screensaver will not reduce the damage to the eye with the eye of high load.
The best way to relax your eyes is to relax your eyes in time. The "20-20 rule" is still useful: take eyes for 20 minutes, move your eyes off, and look outside of 20 feet.
At the same time, do not randomly use eye drops, especially the eye drops that claim to be able to remove eyes blood silk, cool and clear eyes. Only artificial tears are the only kind of non-prescription eye drops that you can safely buy from a drugstore.
Of course, resting the eyes is better than any eye drops!
