A good bag roller for the eye can help you get rid of bags and puffiness which can often be a sign of aging.
Although in many cases the bags and puffiness is caused by age, in some cases it is due to a variety of other factors such as a lot of extra body fat, lack of exercise, etc. Also, if you can get rid of bags and puffiness you may find that you have a healthier eye. It’s not a very exciting topic, but you can look in the section about roller bags and puffiness to find out more about how to get rid of it.
A quick read of the trailer shows that the players in the game are not aware of their own eye-related problems. Just as in the video, the leader has to take care of his own eye-related problems to avoid becoming distracted by stuff or the like.
You could also look in the section on exercise to see how to cure your puffiness.
The goal of roller bags is to help your eyes stay dry. Also the goal of puffiness is to help your eyes look a bit more defined. Both of those goals are achieved by exercising. However, the first one is easier to achieve than the second one.
