Is there a way to reduce the particle opacity when the particle itself is getting closer to the camera ? ( like snow or rain)

Hey guys !

Im working on a snow particle system and there is something wrong with it …

I want the snow to be clearly visible from far away and thats fine but i want the snow to become less visible the closer its getting to the camera, so you cant see the particle details… I dont know if im searching for reducing opacity or if im more looking for getting it blur when its closer …

I just want something to cover the details of my particle… So by reducing the opacity or by getting it blur the more its getting close to the camera.

I searched for it but never found anything… Anyone may have an idea how it can do that ?

Sorry if my question is not clear. Thanks ^^
