How to make a makeup tutorial if I wear glasses?

I wear glasses, and I do not have contacts or anyone else to put makeup on. I film with an iphone and do makeup at a vanity. Without glasses, I have 20/100 (if someone can see something from 100 ft away I have to be 20 ft away to see it) vision and am very nearsighted. How do I film a makeup tutorial.

If I was you I would set up the Iphone at face level on the vanity or some kind of surface with the phone's screen quite close to the mirror, just so you can have a rough picture of if you're in the view of the camera lens while recording, and the benefit about doing a makeup tutorial is that the camera can be quite close to your face so I would get as close to the camera as possible while doing the tutorial since it won't look weird because you would just be giving people a better view of whets going on (dulce candy places the camera right at her eyes when she does her eyes on camera!) So, with the camera nice and close you would be able to not only slightly see the video's reflection in the mirror as you record, but you'd also be able to grab a hand held mirror and hold it right beside the camera (or closer if its a face shot) and be able to see quite well while applying makeup! I think being able to see things better when they're close up is more beneficial with makeup tutorials, and though you may not be able to see perfectly clear, as long as you can put makeup on without glasses you can do a tutorial no problem! Its just all about camera placement.
