Leaf Miner Defense on Tomatoes?

Leaf Miner Defense on Tomatoes?

I'm seeing signs of leaf miner damage on my tomato plants. Doesn't look major at this point, but I'd like to fend them off if possible and get a yield from the plants. Any suggestions for plant defense against the 'miners? The simpler the better; this is my first garden so advanced techniques will be way beyond my skill level. Tomato variety is Cherokee Purple, if that makes a difference.
