Kitten eye discharge

Alyssa

I just adopted my Hemi baby from a licensed rescue about a week ago. He is approximately 3 months old and UTD on shots. But I noticed when we got home that he has bad eye discharge... it comes out clear but crusts up under his eyes, i wipe it off about once a day. Some days it's worse than others and doesn't seem to bother him much, he's still very playful and full of energy. But i was wondering if this is normal? Should I take him to the vet?
