It's a sunny day. The sun will again
It's a sunny day. The sun will again blind you when you go out. You can close RS gold your eyes partially and keep them that manner or put on sunglasses. Whatever you decide to do, you'll always keep back some of the light that's shining in your eyes.
In the preceding example, depending on the situation the eyes could be open cheap RuneScape gold or closed. The amount of light you filter is contingent upon the amount of sunlight available. This is a concept I call dynamic filtering, and it is a concept that can be recognized throughout the world.
