That is a pretty broad question but yes the effect is called bokeh and the BF effect simulates light glare on the camera. To get a similar effect you’ll need a simple semi-transparent GUI Texture and some very basic script.

  1. Using Photoshop start by creating your GUI Texture with the bokeh effect. A series of semi-transparent, slightly blurred circles work well. Ensure they’re set with a transparency and save your final image with an alpha channel.

  2. In Unity place your GUI Texture in the scene and apply a transparency shader. You should see the bokeh texture on screen and be able to see through it.

  3. With script we want the bokeh to only show when a light source is in view. You could do this by placing a script on the GUI Texture which checks for items with a specific tag. If “tag” is visible, turn on bokeh. Alternatively you could attach your script to the light itself, so when visible the GUI Texture is enabled. Example:

    function OnBecameVisible() {
    guiTexture.enabled = true;
    }

    function OnBecameInVisible() {
    guiTexture.enabled = false;
    }

You can create a simple similar looking effect by placing a plane in front of the camera, which contains a texture with desired ‘dirt’, then you could use a particle shader such as multiply altough that would give a very static effect. There are youtube tutorials how to get better results with this technique.
