Particles Blurry At Distance?

Hey everyone! I’m working on particles and I’m really new to this but I have followed quite a few tutorials.

I do have a recurring problem where particles look really blurry far away and clean and clear up close. I have a gif here Screen capture - e1cc524bd9a13f78c9029dcf895c44d2 - Gyazo

Does anyone have any tips to make it not so blurry at a distance?

Thank you!
