Trouble with UV Texture

I’m new to Blender and I’ve been working on this eye. I see my UV map in texture paint and in the UV editor but, when I render the image, it’s invisible.

In the blend file you supplied:
Mistake 1 - You didn’t pack your textures so cannot recreate your scene exactly because only you have the eye texture. Please always include textures in the future (File / External Data menu)
Mistake 2 - In the outliner window you have set the Sphere.001 object not to be renderable (greyed out camera icon)
