I have some glares on my spectacles will that cause any rejection for neet 2020..?and what happens if we get rejected!?

If you have uploaded an image which has you wearing glasses, ideally it might not be accepted. NTA will notify you to upload the image once again during correction window from January 15th to January 31st. You will receive a notification either at your regisrered email or mobile no#. You can change it then. But if you do not get any notification, you are good.
