Get your eyes checked to make sure there isn't a medical issue with your eyes. Most orbs are the result of light reflecting off dust particles in the air.
The spiritual answer, depending on the colour these orbs could be spirits, faeries, or any number of spiritual creatures. However, the way you describe it I'm inclined to belief it's dust or an eye condition. You could try meditating when you see these orbs, or try skrying or another divination technique to try and communicate. But, again, rule out anything medical first.
