I don't know if your Betadine contains alcohol. Just want to remind you that it can not contain alcohol which will damage your eyes. You can first try the one you brought on some sensitive mucus on your body or cut on your body to see if there is any irratation. The right one does not hurt the cut at all. In China we don't have the povidone Iodine for the eye, so the Chinese eye doctors make publications on using diluted chinese made povidone Iodine 0.5% to compare with the eye povidone Iodine in 5% made in US, and it works and people would tolerate it using for 5min then wash it out. But povidone iodine without alcohol should be much more expensive than the ones with alcohol. The names are confusing. You need to be careful.
