Can I actually observe the curvature of the earth with my eyes? When I look out towards the horizon, specifically a large body of water, it appears to me that it's very slightly curved. Is this possible or are my eyes acting like small fish eye lenses?

Yes, you can. If you were to stand on the shore and watch ships sailing directly away from you with binoculars, you would notice that they slowly disappear over the horizon. This is because of the curvature of the planet.
