Don't sweat it man, I'm sure it'll be fine! I know a few other pilots who had similar issues with their eyesight and they all ended up getting their medical cert no problem. As long as your optometrist gives you a clean bill of health then I can't see why the assessor wouldn't be satisfied. Just be honest about your prescription and exam results and emphasize that your eyes are healthy otherwise. They're mainly concerned about any underlying conditions or risks, not just your prescription numbers. Trust the doc's assessment.
