I know on the website it says the worst your eyesight can be is +/- 8.00 diopters. But what is that for? Because my prescription had a measure for "OD/OS Sph" and "OD/OS Cyl". Which category is that 8.0 for? My eye doctor said it might be for BOTH the Sph and Cyl added up but he doesn't know for sure. I will upload my prescription if needed. I was hoping someone who knows these terms/had a child with bad eyesight can help me out. This is possible the only thing holding be back from the academy. Thank you guys!
