Why your vision, view, change since you become over 18-22, it becomes kinda clear and not that bright as be4?

I dont mean change in vision in fact of deffects of eyes or other medical reasons, there is the thing I realized, as well as some other people agreed with me, that you start seeing everything more clearly since your off your teen age, view of the world and its colors became kinda darker and not that bright and ';sunny'; as in childhood or teen age. What cause this change?Why your vision, view, change since you become over 18-22, it becomes kinda clear and not that bright as be4?
probably environment.


As an 18+ I don't get to sit around in happy sunny places. Preschool places and children's classroom are decorated with pretty bright things. There's a naptime and recess time.


Now I have no recess, I go from place to place, buildings are not bright colors, roads are black, my car is gray. An office building is void of colors or happy posters.





Think it's just a matter or where people are. Actually my dorm is quite pretty. I have colorful sheets and stuff. Also matter of fact, grey or primer colored paint is cheaper than a brighter one. Which is why most adult places are painted like that. Kiddy rooms are colorful cos they need some mental stimulation to grow. Adults, not so much. Done growing.
