Raindrops are falling on my... glasses?

Question

I live in the UK, where it rains. A lot. I also have the unfortunate necessity to need to wear glasses to see, which means that when it rains (as it is now), I can barely see out of them. This challenge is so that you can all experience the same!

Task

Output ASCII art glasses with a drop of water added each second.

Input

None

Output

A pair of glasses with drops of water on them.

Glasses

Raindrops

A raindrop is denoted by a .. A raindrop is randomly placed on the glasses' lenses. So when a raindrop is placed, the glasses might look like this

 ________________________
|          /__\          |
|    .    /    \         |
|        /      \        |
\_______/        \_______/

If it is placed on a blank space (), an . is placed on the image. If it is placed on a square which already has a raindrop, the drop graduates.

The steps on drops are

• no drops placed:
• 1 drop placed: .
• 2 drops placed: o
• 3 drops placed: O
• 4+ drops placed: @

Rules

• The image should look as though it stays in place. This means that you can either clear the screen or print enough newlines to "clear" the screen. You cannot return a list of steps. Sorry about this, but you should be able to work around that.
• When outputting newlines to "clear" the screen, you must have at least 3 newlines between the glasses.
• The code runs until the glasses are full of fully graduated drops i.e. until the output looks like this:

     ________________________
    |@@@@@@@@@@/__\@@@@@@@@@@|

-1 byte thanks to @ceilingcat.

Explanation:

Try it here. (Thread.sleep is removed so you instantly see the result.)

v->(){                      // Method without empty unused parameter and no return-type
  String q="########",g=" ________________________\n|##"+q+"/__\\##"+q+"|\n|#"+q+"/    \\#"+q+"|\n|"+q+"/      \\"+q+"|\n\\_______/        \\_______/\n\n\n";
                            //  The glasses (with inner spaces replaced by '#')
  for(int t=0,n,x;          //  Index integers
      g.matches("(?s).*[#\\.oO].*");
                            //   Loop (1) as long as the glasses still contain "#.oO"
      Thread.sleep(150)){   //   And sleep 150ms after each iteration to give the animation
    for(;                   //   Inner loop (2)
         (x=g.charAt(n=(int)(Math.random()*g.length())))!=35&x!=46&x!=111&x!=79;
                            //    To find the next '#', '.', 'o' or 'O' randomly
    );                      //   End of inner loop (2)
    g=t++>0??               //   Flag so it prints the initial glasses without a raindrop
      g.substring(0,n)+(x<36?".":x<47?"o":x<80?"@":"O")+g.substring(n+1):g;
                            //    Add a raindrop on this random position
    System.out.println(g    //   And print the glasses
        .replace('#',' ')); //   After we've replaced '#' with spaces
  }                         //  End of loop (1)
}                           // End of method

The above link uses 30 lines instead of 3, but you can see it with 3 if you resize your browser window to be small enough vertically. Change time.sleep(1) to time.sleep(.1) for 10x speed.

Needs to be golfed down quite a bit;

c;f(r,q){for(char*m=" ________________________\n|**********/__\\**********|\n|*********/    \\*********|\n|********/      \\********|\n\\_______/        \\_______/\n";c<216;r=rand()%144,m-=135)for(system("clear");*m++;putchar(*m^42?*m:32))q=--r?*m:*m^42?*m^46?*m^111?*m^79?*m:64:79:111:46,c+=q!=*m,*m=q;}

I run it with the following test stub

main()
{
    srand(time(0));    
    f();
}

Previous answer was wrong, it did not take into account a raindrop falling on a @. Apparently not a requirement. Some bytes saved.

This terminates with an error thrown, but this definitely terminates as soon as the full glasses are printed.

• Saved 13 bytes by putting the printing into a lambda, and changing the assignment to use tr (duh)
• 8 bytes loss with the 1 second requirement.
• 10 bytes gain by using the gsub trick instead of interpolation (seen & adapted from mbomb007's Python answer).
• 12 bytes gain by removing the lambda printing now that the print is written only once >.>
• 1 byte gain by making all the \\ be a, then changing back inside the tr
• 7 byte gain by putting the changing the spaces on the last line with another x (duh). In case some of you guys are wondering why this doesn't affect the main loop : the main loop doesn't consider the last line to determine its x.
• 1 byte gain by removing the at the end of the top of the glasses

Yay < 200 bytes :D
