Can someone please trade me eyes?

It's unknown how they still have sight 
Every since I was 6 the sense have witnessed gruesome events 
Now my eyelids flicker past them very seldom 
My lacrimal glands have trouble producing saline 
I find it nearly impossible for beatitude to gleam from my eyes
And I cannot search for something that my eyes feel sorrow for 

Let me at least borrow yours? 
Please 
So I can see how it feel to grieve 
So that tears of joy can travel down my cheeks 
I want humor to cause me to wink 
I want my reflexes to cause me to blink 

Pleeeeeeaaassseeee?
I stand there in the face of danger 
When I should be aware 
Instead I just stare 
...
No glare 
Just dispirited 
The statical behavior that my eyes inherited 
Suppress me from all charity 

I'm begging you 
No one looks me in my face and feels warmth and comfortability 
All that they see is two white igneous rocks
When I wish that they can see marshmallows 

That's why I need your help 
The optometrist said there's nothing that he can do 

That's why I'm coming to you 
I just wanna be inspired by life 
Can you show me how the world look again just for one day?
